Can Possums Chew Through Electrical Wires?

Can Possums Chew Through Electrical Wires?

If you’re experiencing random power cuts, can see bite marks on electrical wires, and hear noises coming from your roof, chances are you have possums chewing through your cables. We as electricians see it all the time, and it is a massive inconvenience for homeowners across Sydney.

Pesky possums have a habit of chewing through electrical cables, leading to exposed wires, short circuits, power outages, and even fires.

To rub salt in the wound, most wiring is hidden behind walls or in the roof, and this makes it difficult to spot whether a possum is active before it’s too late.

Here is our guide to recognising whether possums are chewing on your electrical cables and the steps you can take to stop rodents from getting to your electrical work.

Why Do Possums Chew Electrical Wires?

Possums are curious animals and chew on things to maintain their teeth and in search of food. 

They also chew cables if they are blocking their way as they seek out holes inside your walls or roof to nest.

Is It Dangerous for a Possum to Chew Electrical Wires?

A possum, rat, or mouse nibbling through your cables can be very dangerous. They may chew a cable all the way down to the copper wire which has the potential to cause electric shocks or fires.

If you think you have possums chewing through your cables, you should get the problem sorted sooner rather than later to avoid more extensive and costly damage.

Signs a Possum Has Been Chewing Cables

As we mentioned, it can be tricky to recognise whether you have possums chewing through your cables because most of their activity occurs inside the walls of your house, or in the roof. They are also most active at night when us humans are asleep.

Here are the signs you should look out for:

  •        – Bite marks on cables
  •        – Frayed wires
  •        – Droppings near cables
  •        – Running, scratching, or banging noises coming from your roof, particularly at night
  •        – Seeing possums near your home
  •        – Flickering lights
  •        – Blown fuses
  •        – Random power outages
  •        – Burning smell from exposed or overheated wires

If you’re wondering whether it could be rodents like rats or mice chewing your cables, you can usually tell whether it’s a possum because they are much larger animals – about the size of a cat – and they make loud banging sounds. Rodents are smaller and tend to be quicker as they scurry through your walls and roof.

How Can I Stop Possums Chewing My Electrical Wires?

Unfortunately, once you have possums living inside your walls or roof, they can be very difficult to get rid of and you’ll need to call in professional pest removal. 

Before you get to that point, here are some DIY steps you can take as a precaution: 

  •        – Cover wires in chew-resistant cable covers so possums can’t gnaw through
  •        – Spray possum repellent in areas where they can get into your home, such as holes in your roof or fences
  •        – Fill holes in your roof and walls
  •        – Get possum guards for your gutters
  •        – Trim trees away from your gutters so possums can’t climb on your roof
  •        – Install motion activated lights to scare them off

If possums have already made your roof their home, you should hire a possum catcher who can remove and relocate them in a humane way. A possum catcher will also seal any entry points in your home to prevent them coming back.

As a native animal, possums are protected in Australia and only licensed possum catchers are able to remove them. You should not try to remove them yourself.

What Should I Do if My Cables Are Damaged?

If you have damaged electrical wires, or suspect that the cables inside your walls or roof have been damaged, call an electrician and we can come and check it out.

It’s better to act sooner rather than later as the longer possums are left, the more costly and extensive the damage will be.

When to Call a Professional

You should never attempt to repair, replace, or install any electrical wires yourself because exposed or damaged wiring can cause safety hazards like electric shocks or fires. 

Instead, give our team at Radiance Electrical a call and we can inspect the issue. Our 24/7 emergency electricians can quickly address wiring problems across Sydney’s North Shore and Northern Beaches to keep your home safe and running effectively.

Why Do My Lights Flicker When the AC Comes On?

Why Do My Lights Flicker When the AC Comes On?

Why Do My Lights Flicker When the AC Comes On?

Have you noticed your lights flickering when you turn your AC on? Probably. The truth is that it is a very common occurrence and usually something that you don’t need to be worried about. But sometimes it could be a sign of a more serious problem with your electrics. So, why are your lights flickering when your AC starts, and how can you prevent it from happening? 

What Happens to Your Lights When the AC Turns On?

Air conditioning (AC) units require a huge amount of energy to start up and often use more electricity than other household appliances.

Your home’s electrical system has a limited amount of energy and can only be used to power a certain number of things at one time. 

So, when you turn on your AC, the sudden heavy load on the electrical system may mean some power is temporarily taken from elsewhere. In this case, it could be taking power from your lights which will cause them to briefly flicker.

Starting up your AC can also cause a short voltage drop on the rest of the house. This is because the AC compressor draws a large amount of electricity to start – called an inrush current – and this sudden surge of power causes a temporary dip in the voltage supplied to the other appliances in the home.

Is This a Problem?

Lights flickering when your AC turns on is normal, typically only last for a fraction of a second, and should only dim your lights slightly (around 3-5%). If this is the case for you, it’s probably nothing to worry about and you can easily live with it.

However, there are certain signs to watch out for which signal that flickering lights when your AC turns on is the byproduct of a bigger problem. These include: 

  •         – Lights rapidly turning on and off for a prolonged period
  •         – Buzzing and crackling sounds
  •         – Lights losing half or more of their brightness

If you notice any of these things, it may be time to call an electrician. They could be a sign of:

  •         – Damaged wires – this is a fire hazard and can cause more severe damage to your electrical system
  •         – An overloaded circuit – can cause fires or electric shocks
  •         – A weak or broken AC capacitor – An AC capacitor supplies energy to the air conditioning once it is up and running. If your capacitor is weak or broken, it can cause your electrics to trip or prevent your AC from working altogether
Causes of flickering lights when the AC is on

How Do I Stop Lights Flickering When AC Turns On?

Your lights flickering slightly and only for a few seconds when you switch your AC on is generally not a problem. But if it is impacting you, you may need to have the AC capacitor or entire unit replaced.

Another option could be to install an AC soft starter which will reduce the initial surge of electricity when you turn your AC on. This could be particularly beneficial for households powered by solar energy or homes with older electrical systems.

In some homes with older electrical systems, the system may not be able to cope with high power surges and could be more prone to overloaded circuits. In this case, the whole circuit may need re-wiring.

Are Surge Protectors Really Worth It?

Are Surge Protectors Really Worth It?

Are surge protectors really worth it cover

There are two types of surge protectors – whole-house surge protectors defend the entire property against electrical overload, while power strips with built-in surge protectors prevent damage to connected appliances. 

Surge protection devices are a worthwhile investment for ensuring electrical safety of a home. However, are they truly necessary? As electricians, this is a question that comes up a lot. Let’s breakdown how important surge protection is for your home.

How Do Surge Protectors Work?

Surge protectors act as a safety net against electrical surges for connected electrical systems and devices. 

An electrical surge is a sudden spike in voltage in a power line or circuit. Surges can come from lightning hitting an open power line, faults in the power line, or internal issues in the home’s electrical system. When a device is exposed to a voltage higher than its rated capacity, it can become damaged beyond repair. 

Surge protection devices either block or short the power current in the event of a surge, preventing electrical damage to connected devices. The excess current flow is either diverted into the ground (for whole-house surge protectors) or dissipated as heat. 

Most modern appliances and devices include built-in surge protectors in line with modern electrical safety standards. A built-in surge protector stops the appliance from overheating or catching fire – but once it activates, the appliance will no longer work. External surge protection devices stop electrical surges from damaging appliances. 

Types of Surge Protectors

Whole-House Surge Protectors

Whole-house surge protectors are installed at the point of connection between the electrical system and the main power supply, typically within the switchboard. Whole-house surge protectors stop the home’s electrical systems from being damaged by blocking power surges from the main line. Whole-house surge protectors have a high capacity to handle larger electrical surges and must be installed by an electrician.

Power Boards With Surge Protection

Power boards with surge protection protect devices and appliances that are plugged into the circuit. No professional installation is required – plug the power board into a household socket and use it like any other power strip. Power boards with surge protection have a lower capacity than whole-house surge protectors and offer limited protection.

types of surge protectors

How Long Do Surge Protectors Last?

The lifespan of a surge protection device depends on the number of surges it is designed to withstand over its lifetime. A cheap surge protector is usually single-use; after absorbing a surge, it will need to be replaced. Higher-quality surge protection devices are designed to defend against multiple surges over a few years, automatically resetting after a surge has passed.

Quality surge protectors have a visual indicator, like an LED light, that shows whether it’s still working or has expired. A cheaper surge protector may not have the light indicator, which makes it difficult to know whether it’s still working or not.

With no surges, the devices can work for up to 3-5 years and then will need to be replaced.

Should You Install Surge Protectors In the Home?

Yes, surge protectors should be installed in the home. Surge protectors will protect your appliances, devices and the overall electrical system of your home from a power surge. It’s much cheaper and easier to replace a surge protection device than to replace a damaged appliance or rewire your home. 

Homes with overhead power lines are more at risk of external surges from power line disruptions or lightning strikes. A 2023 study in the International Journal of Electrical Power & Energy Systems found that lightning strikes on high voltage power lines had a higher probability of causing electrical surges and damage to homes in the surrounding area.

How Long Do Hot Water Systems Last?

How Long Do Hot Water Systems Last?

How long do hot water systems last?

Like all home appliances, hot water systems are not built to last forever and will eventually need to be replaced. If you’ve noticed inconsistent temperatures or long waits for hot water to come through, it may be a sign that your hot water system is reaching its end of life and will need to be upgraded.

Whether you’re thinking of upgrading an ageing hot water system or weighing the costs involved in installing a new one, here’s what you should know about average hot water system lifespan based on the different types.

How Long Does A Hot Water System Last On Average?

The average operational lifetime for a hot water system is between 8 and 20 years – most systems will become less efficient after 10 years. As the storage tank naturally degrades, it starts to lose more heat through the walls, resulting in higher energy costs to keep the water heated. 

Problems in the heating element of the system can also cause a hot water system to fail or lose efficiency. Gas systems use a pilot light, while electric systems use two or more heating elements to heat water. If the heating elements are no longer in working order, the hot water system will need to be replaced. However, if the issue lies in connectivity issues (such as a tripped electrical breaker), repairs may be enough to get the hot water system back on. 

Hot water system manufacturers provide separate warranties for both the storage tank and the heating elements. These warranties can give you an idea of how long each component will last — storage tanks have warranties ranging from 7-12 years, while warranties for heating elements last between 1-2 years. 

Lifespans for Different Types of Hot Water Systems

As you might have guessed, different types of hot water systems have varying lifespans. Generally, a gas-heated hot water system will have a shorter lifespan compared to an electric-heated system. 

Electric hot water systems also come in the form of solar-powered water heaters and heat pumps. Both solar and heat pump hot water systems are more energy efficient to run, and can last up to 20 years with proper care and maintenance. Heat pump water heaters use 30% of the energy of a conventional electric hot water system, and solar hot water systems make use of generated electricity to offset the power requirements of heating water. 

Continuous flow or tankless hot water systems have the longest lifespan, with most models lasting 20 years on average. Continuous flow systems can be either electric or gas heated and provide hot water on demand without requiring water to be heated up in a tank. 

 

Type of hot water system

Average lifespan in years

8 – 12

Electric heated tank 

10 – 15

Solar powered 

10 – 20

Heat pump

10 – 15

Continuous flow (tankless)

15 – 20



What Affects How Long Hot Water Systems Last?

There are 3 main factors that impact how long a hot water system will last — the material, type, and usage of the system. 

Material

The storage tank of a hot water system can be made using different types of insulating material to minimise heat loss from water. Stainless steel coated with vitreous enamel is the most common material, but there are also copper and glass-lined tanks on the market. 

Stainless steel tanks tend to last up to 12 years before requiring replacement, while glass or enamel-lined tanks will last about 10 years. Copper tanks have the longest lifespan of up to 20 years.

Type

Hot water systems that use storage tanks will have a shorter lifespan compared to a tankless system. Stored water in the tank will gradually corrode the walls of the tank over time, which may result in greater heat loss or even leaks. Continuous flow systems only heat water as it flows, which reduces the rate of degradation.

Usage

Heavy usage of a hot water system will place more stress on its heating components, which accelerates wear and tear. A large family household with high hot water usage can cause the hot water system to have a shorter lifespan.

Considerations for Replacing A Hot Water System

When it’s time to replace a hot water system, it’s worth weighing up the estimated lifespan of each model against the needs of the household. Gas hot water systems can supply high volumes of hot water but have shorter lifespans, while electric hot water systems are more energy efficient in meeting lower hot water demand and tend to last longer. If the home has a solar system, choosing to install a compatible hot water system can result in significant cost-savings in the long run. 

The installation of the hot water system should also be factored into the decision. Switching from a gas hot water system to an electric-heated one will be more complex due to the need for rewiring the necessary connections. Installation for electric hot water systems must always be carried out by licensed electricians who will ensure safe and proper operation.

Circuit Breaker vs. Fuse Box: What’s the Difference?

Circuit Breaker vs. Fuse Box: What's the Difference?

Circuit Breaker vs. Fuse Box: What's the Difference?

Both circuit breakers and fuse boxes serve the same purpose – to supply power from the main electrical grid and protect against electrical overload. While shared in purpose, a circuit breaker and a fuse box differ in how they protect against electrical faults. 

What Is A Circuit Breaker?

A circuit breaker is a device that controls the distribution of electric supply to the home while protecting it from electrical hazards. Circuit breakers use a switch mechanism that automatically cuts off the flow of electricity when an electrical fault is detected, preventing wiring from overheating and causing damage to appliances. Affected switches can be switched back to restore power to the circuit once the issue is addressed.

What Is A Fuse Box?

A fuse box is a device that distributes electrical power to different circuits in the home – similarly to a circuit breaker. However, a fuse box consists of a series of fuses rather than automatic switches to protect against electrical overload. When the circuit overloads, the respective fuse melts and breaks the circuit. Once a fuse is “blown”, it will need to be replaced with a new one to restore power to the circuit.

How To Determine If A Home Has A Circuit Breaker Or A Fuse Box

Look for an electrical panel or box within the home – it will usually be located close to the entrance of the house, either outside the front door or in the main hallway. Examine the inside of the panel:

• A circuit breaker has a row of plastic switches that may be labelled with areas of the home, like the kitchen or lights. Most modern homes in Australia (from the 1980s onward) are equipped with circuit breakers.

• A fuse box will have round ceramic or plastic holders that contain fuses, which are either screwed or plugged in. Older homes in Australia (those built before the 1980s) may still be equipped with a fuse box.

Comparing Circuit Breaker Vs Fuse Box

Load Handling and Capacity

Circuit breakers are better equipped to handle the electrical needs of modern homes. The maximum load of a circuit breaker ranges from 100 to 160 amps. Fuse boxes, on the other hand, have a significantly lower maximum load handling between 40 and 60 amps. 

To put this into perspective, a modern electric oven draws between 20 and 60 amps, depending on the make and model. Homes equipped with a fuse box may struggle to support the electrical needs of a family.

In terms of circuit capacity, advanced circuit breaker models can support up to 24 individual circuits at a time, which provides more safety and convenience for the home by isolating different electrical areas and appliances. When one circuit trips, the others remain unaffected. In comparison, a household fuse box can only support up to 6 circuits.

Repair And Replacement

A circuit breaker can be easily reset after an electrical overload. To restore power, simply flip the tripped switch back into the “on” position. Flipping a circuit breaker switch can be done without the help of an electrician and is easier to use than a fuse box. 

With a fuse box, however, a blown fuse cannot be used any longer and will need to be replaced. Replacing a blown fuse is a complex process that requires an electrician’s expertise to install the fuse safely and correctly.

Safety Standards

Circuit breakers have been the standard for electrical systems in Australian homes since the early 1980s. During this period, safety devices like Residual Current Devices (RCDs) were installed in switchboards to detect electrical imbalances and cut power.

According to the AS/NZS 3000 Wiring Rules, circuit breakers are required for new homes to ensure a high standard of electrical safety and minimise the risk of electrical fires. 

Fuse boxes in older homes are not compatible with RCDs and have a higher risk of undetected electrical faults, increasing the likelihood of hazards like electrical shocks and fires.

What If My Home Still Has A Fuse Box?

Having a fuse box in the home is not against the law, but it offers less protection and convenience compared to a circuit breaker. If your home still has a fuse box, it’s generally advised that you replace it with a circuit breaker – not only for enhanced safety, but also to provide the home with a more reliable source of power to meet your electrical needs.

Hot Water System Repairs & Servicing Costs: 2025 Guide

Hot Water System Repairs & Servicing Costs: 2025 Guide

hot water system repairs and services 2025 guide

When your hot water system stops working or is taking too long to heat up for a shower, it’s time to call in a professional to take a look at what’s causing the problem. A hot water system can last anywhere between 8 to 20 years (depending on the make and model), during which it may need routine servicing or spot repairs to keep the system in good working order. 

If your hot water system simply needs repairs and is not due to be replaced, a qualified electrician or plumber will be able to identify the problem and address the issues directly –  whether it be a faulty pressure relief valve or burnt-out wiring. So, how much can you expect to pay for hot water system repairs? Here’s a guide to the costs involved.

Average Cost of Hot Water System Servicing

Hot water system repairs in Australia generally cost between $140 and $200. The costs will also change depending on who you book, and the extent of repair work. Hot water system servicing will require the expertise of a licensed plumber or electrician (for electric hot water systems). 

Additional costs may be involved for emergency call-out services or replacement parts needed to complete the repair.

Factors Affecting Hot Water System Repair Costs

The cost of hot water system repairs can vary based on a range of factors, including labour costs, the type of hot water system, and the components that need replacement.

Cost of Labour

The labour costs for hot water system repairs will come down to the provider you choose. Each plumber or electrician has their own hourly rate. On average, electricians in Sydney charge between $80 and $130 per hour.

Hot water system services usually don’t take long; most repair jobs can be completed in 1 to 2 hours. Taking the median hourly rate of $100 for an electrician’s services, a typical repair job for a hot water system will cost $100-$200 based on labour charges alone.

Model and Type of Hot Water System

Hot water systems are either electric, solar or gas-powered – the work required in repairing each system will depend on the type. Electricians are required for repairing an electric hot water system, as they have the requisite experience to identify and rectify electrical issues. 

In addition to the type of hot water system, the specific model of the hot water system will also affect the cost of repairs. Replacement parts may not be as readily available for less-popular or older models, which can drive up the price of parts. In some cases, servicing technicians may have to look for replacement parts from aftermarket sources, which can add to the cost of labour and time for repairs.

factors affecting hot water system repairs

Replacing Hot Water System Components

The cost to replace each hot water system component will also affect the overall cost of repairs. Here’s a list of the costs for hot water system components that often need replacement:

   • Heating Element: $20 – 30

   • Anode rod: $40 – $140

   • Thermostat: $30 – $120

   • Dip tube: $50 – $150

   • Pressure relief valve: $150 – $200

   • Electric wiring upgrades: $300-$800 (often needed for older homes)

   • Pilot light (gas-powered systems): $120 – $200

Location of Hot Water System

Hot water systems located in easily accessible areas (usually on the outside side passage of the property) will not incur any additional fees. However, if the hot water system is located in an area that is more difficult to access or requires permission (such as in a strata property) it may result in additional fees from the electrician or plumber.

Should You Repair or Replace a Faulty Hot Water System?

Repairing a hot water system will almost always be more cost-effective than replacing the system outright. However, there are instances where the hot water system may be too outdated or in such poor condition that it is not worth repairing. 

As a general rule, a faulty hot water system will require replacement after 10-15 years, especially if it consistently requires repairs. Replacing a hot water system will involve a higher upfront cost, but it will be more reliable in the long run.

How Many Downlights Per Room? LED Downlight Guide

How Many Downlights Per Room? LED Downlight Guide

How Many Downlights Per Room? LED Downlight Guide

LED downlights are now the standard for new homes and modern renovations. LED downlights are energy efficient, come with a long lifespan, and are better for the environment. Unlike traditional light fixtures that extend from the ceiling, downlights are installed from inside the ceiling, resulting in a narrower beam of light with a 35-degree angle. As a result, each room must have the right amount of downlights to ensure sufficient lighting. 

We’ve created this guide to help homeowners like you determine the right number of downlights for each room and provide tips for downlight placement to avoid pockets of overlap or poor lighting conditions. 

How Many Downlights Do You Need Per Room?

Generally, there should be at least one downlight for every 1.5 m² of the room’s area. Using this rule, you can calculate how many downlights are needed in a room using this simple formula:

(Length of the room in metres X Width of the room in metres) ÷ 1.5 = Number of downlights

For example, a room that is 4 metres long and wide will need (4×4) ÷ 1.5 ≈ 10 or 11 downlights. This formula is only a rough guide, however, as there are other factors to consider when placing downlights in a room. 

Factors Affecting the Number of Downlights Needed

Type of room

The number of downlights in a room will depend on its lighting needs. The kitchen requires a higher level of brightness than the bedroom — cooking demands much more precision than reading in bed. Higher-brightness rooms typically need one downlight for every 2.0 m² of space; these include rooms like the kitchen, home office or study, dining room, and the bathroom. Parts of the home that require less intense lighting are the areas of relaxation, such as the living room and bedrooms, as well as transitory areas, like staircases and hallways. 

Height of the ceiling

Standard Australian homes have a ceiling height of 2.4m. Homes with ceiling heights greater than 2.4m have more space, which leads to a need for additional downlights to light up a larger area. As downlights are placed at the same height as the ceiling, the light beams are spread out over a longer distance, softening the overall brightness of the light.

Colour of the walls

Lighting principles include the colour of the walls in each room. Dark wall colours absorb more light, while light wall colours reflect light. The darker the colour of the walls in a room, the more downlights will be needed to ensure that the space does not feel too dim. The opposite is also true — rooms with brightly coloured walls (ie., white walls) generally need fewer downlights to feel sufficiently lit. 

Even/specific lighting

Downlights shine a narrow beam of light from the ceiling, ideal for lighting up specific areas of the home for an aesthetic effect. Placing a downlight just above a reading corner of a living room while keeping the surrounding area dim can create a cozy atmosphere. Homeowners who want dynamic lighting in the home may not necessarily opt for evenly spaced-out downlights; instead choosing to place downlights at selective locations. 

factors influencing How Many Downlights Per Room

Considerations for LED Downlight Placement

After working out the number of downlights needed per room, it’s also important to consider placement for adequate lighting. When planning for downlight placement, keep these tips in mind:

1.   Ensure sufficient distance from walls—Downlights emit light in a narrow cone; positioning them too close to the wall will cause shadows to form near the top of the wall, which can make a room appear gloomy. Avoid this by placing downlights at least half a metre from adjacent walls or corners. 

2.   Avoid placement directly over workstations — Placing downlights directly over a table or kitchen countertop can cast a shadow on the work area when it is used. Instead, place downlights on the side of workstations to prevent the body from blocking light.

 

LED downlights are available in various colours and intensities. Warmer LED downlights are ideal for creating a cozy atmosphere (best for bedrooms), while white downlights tend to create a more vibrant feel that suits a home office or living room. Some downlight systems also feature dimming to adjust the brightness level in the home, offering greater flexibility for different times of the day. 

A good rule of thumb for downlight installation is to estimate the number of downlights needed for each room, and then plan for placement based on the needs of the room. Whatever your plan, you’ll ultimately need a licensed electrician to carry out downlight installation and, if necessary, provide the LED bulbs. 

At Radiance Electrical, we can provide advice on the number of downlights you need for each room and carry out downlight installation for homes in Sydney. We also go above and beyond to perform a free electrical inspection for your home with every job we complete. Contact us to get a free quote for downlight installation for your home.

Circuit Breaker Tripping? Here’s Why & What to Do

Circuit Breaker Tripping? Here's Why & What to Do

why is circuit breaker tripping

When a circuit breaker is overdrawn, it can cause all power to be suddenly cut off or ‘trip’. Tripping circuit breakers are both an inconvenience and a hazard. So, why do your circuit breakers keep tripping, and how can you prevent it from happening?

How does a circuit breaker work?

A circuit breaker is an essential part of a property’s electrical system.

The circuit breaker is the main connection point between the property and the main power supply — it routes and manages the power supply to different parts of the home, including lighting and power outlets. A circuit breaker prevents electrical overload in the home by immediately cutting off the connection when too much power is drawn by an appliance. Electrical overloads in appliances can result in overheating, which in turn can cause electrical fires to occur.

Essentially, a circuit breaker is what protects the property from electrical faults and emergencies.

What Causes A Breaker To Trip?

There are several potential causes of a circuit breaker tripping. In some cases, the root cause may not be the breaker but the wiring system of the house or a faulty appliance.

1. Overloaded circuit

An overloaded circuit is the most common reason for frequent breaker tripping. When the system is demanding more than a ‘safe’ limit of power within the home, the circuit breaker will automatically cut off power. This can happen if several high wattage appliances that are connected to the same circuit are used at the same time, causing the circuit to heat up and trigger the breaker. 

2. Faulty appliance

A damaged or defective appliance can draw more power than necessary, overloading the circuit and tripping the circuit breaker. If the breaker constantly trips during the usage of a specific appliance (especially when no other appliances in the same circuit are being used), it is most likely that the appliance may be the cause. You can also usually tell when the appliance becomes unusually hot when in use.

3. Short circuit

Short circuiting can occur when two or more live wires come in contact with each other, causing the circuit to rapidly heat up. Short circuits will cause the circuit breaker to trip to avoid the risk of an electrical fire.

4. Ground fault

A ground fault occurs when a live wire comes in contact with a ground wire or a conductive material that is connected to the ground. This causes the circuit to flow on an unintended path into the ground, causing a surge in electricity that trips the breaker. 

What To Do When The Circuit Breaker Trips

When a circuit breaker trips, most of us simply flip the affected switch back into position to restore power to the circuit. However, while it will fix things temporarily – this action is not always advisable, as it can result in damage to the circuit breaker after repeated attempts.

The first thing to do after a circuit breaker trips is to turn off recently used appliances in the room and check for any signs of electrical hazards. Appliances that feel hot to the touch may be a sign of faulty internal wiring that is causing the breaker to trip.

Signs of electrical fire include blackened power outlets, melted wires, or a burning smell in the air indicate a high risk of an electrical fault in the circuit.

If there are no signs of an electrical fire, consider rearranging the location of connected appliances. Generally, high-wattage appliances like heaters or hairdryers should be plugged into separate circuits in the home to avoid overloading issues.

When To Seek Professional Electrical Services

If the circuit breaker continues to trip unexpectedly, it’s time to call out an electrician. You should never attempt to repair or replace any part of the circuit breaker on your own due to the risk of electrocution. Instead, call an electrician to inspect the condition of the circuit breaker and the electrical system of the home. Get the help of a licensed electrician when:

  •       –   The circuit breaker trips regardless of the number or arrangement of appliances used
  •       –   The lighting in the home flickers or dims before the circuit breaker trips
  •       –   There is a burning smell or evidence of an electrical fire near outlets after a circuit breaker trips

An electrician can identify the cause of frequent breaker tripping and offer the appropriate solution, whether it involves repairing the circuit breaker or replacing it with a modern model. In some cases, the problem may lie with a fault in the electrical wiring between the main power line and the property — this will require the expertise of a level 2 ASP electrician.

Circuit Breaker Replacement Costs

Circuit Breaker Replacement Costs

circuit breaker replacement costs

A circuit breaker will play a crucial role in ensuring the safety and functionality of a building’s electrical system. The circuit breaker is designed to protect an electrical system against damages like an overcurrent, overload, or short-circuiting, which can cause serious hazards like fires.

Just like any piece of electrical equipment, a circuit breaker can wear out over time and must be replaced every 15-20 years. Circuit breaker replacements can cost between $200 and $500. As a property owner, it’s important to recognise when your circuit breaker may need replacing and the factors determining circuit breaker replacement costs.

What is a Circuit Breaker?

A circuit breaker is an electrical switch that controls the flow of electricity and power into a building. The primary function of a circuit breaker is to detect any faults, like overcurrent/overload or short circuits, and protect the electrical circuit from damage caused.

When a building has too much current or experiences overload issues, a circuit breaker will cut the power until the problem is fixed. Both a circuit breaker and a surge protector work to protect the electrical system from a sudden power surge. 

Generally found in the garage, basement, or laundry, circuit breakers are an essential safety mechanism for every home. Particularly with the increased demand for electricity and appliances in a modern home, circuit breakers must operate seamlessly to prevent the risk of electrical hazards and fires.

Types of Circuit Breakers

Different circuit breakers are available to suit different needs and requirements in a home’s electrical system. The most common types of circuit breakers include:

Single-pole​

The most common type, single-pole breakers protect one wire and typically rate for 15-30 amps. Single-pole breakers supply electricity for most devices and small appliances in a home.

Double-pole​

Made of two single pole breakers to protect two wires and generally supply electricity for larger appliances like clothes dryers and water heaters – rating for 15-200 amps.

Residual Current Device (RCD)​

An RCD is a specialised circuit breaker that detects any power current leakages and immediately cuts off the electricity supply.

Ground Fault Circuit Interrupters (GFCI)​

A GFCI is suitable for potentially wet areas, like the kitchen or bathroom. A GFCI breaker has the same functions as a standard circuit, in addition to cutting the power when electricity flows to a grounded element.

Arc Fault Circuit Interrupters (AFCI)​

More sensitive than regular circuit breakers, an AFCI breaker detects when there is a sudden surge, or “arc”, in electricity and cuts the power current immediately. 

Signs Your Circuit Breaker Needs Replacing

Most modern circuit breakers last 15 to 20 years. However, areas with frequent outages or power surges may need replacing sooner – it is vital to observe and note any signs that your circuit breaker may need replacing. 

Signs that a circuit breaker needs replacing include frequent tripping of the breaker, flickering lights, bulbs burning out often, burning smells, the breaker won’t reset, or visible damage to the breaker. It’s essential to check your circuit breaker after any external factors like heavy storms, lightning strikes, and water damage to see if any damage to the breaker may have occurred. 

If you’ve noticed any of the above signs contact a licensed electrician to assess and fix the electrical issues safely. 

factors influencing the cost of circuit breaker replacements

Factors Influencing the Cost of Circuit Breaker Replacement

Not all circuit breaker replacement jobs are the same; some are simple, whereas others are more complex. The variable factors that go into replacing a circuit breaker will influence the overall cost considerably. 

Type of circuit breaker

Some circuit breakers are more expensive than others – the type of circuit breaker you need will significantly impact the overall cost of the replacement. It’s also worth noting that replacing main circuit breakers, like GFCI, AFCI, and RCD, will cost more than replacing individual breaker circuits, like single-pole or double-pole. 

For example, a single-pole or double-pole circuit breaker generally costs ~$150, while a main or speciality circuit breaker can cost up to $300 to replace. 

Number of breakers

Generally, most buildings have at least 20 circuit breakers and 1 to 2 circuit breaker panels. An average-sized residential building has between 20 and 30 circuit breakers – usually including single-pole, double-pole, and Ground Fault Circuit Interrupter (GFCI) breakers. Electricians can charge less per breaker when installing or replacing multiple circuit breakers at the same time. 

Additional materials

Circuit breaker replacements can require additional materials, like new wiring, connectors, fasteners, and junction boxes – increasing the overall costs of replacing your circuit breaker. 

Permits and inspections

In Australia, we have to comply with your local electrical codes for all electrical work – this can include potential permit requirements and regular inspections. Depending on the building, permits and inspections ensure the job is done safely and aligns with your area’s code. Permits and inspections come with an added fee, contributing to the overall costs of the electrical job. 

Cost of electrician

We’ve also got to do the manual work! Labour costs/general costs of hiring an electrician will include call-out-fees and travel fees. You’re also paying for someone who knows what they are doing – as electricians, we follow stringent electrical regulations to ensure all electricians can safely and effectively work with residential and commercial circuit breakers. 

At Radiance Electrical, our electricians are level 2 certified – which means we have the skills, knowledge, and training to not only fix and replace all circuit breakers and switchboards, but we can also deal with more complex electrical work related to connecting power to mains.

Kitchen Range Hood Installation Costs: 2025 Guide​

Kitchen Range Hood Installation Costs: 2025 Guide

Kitchen range hood installation 2025 cost guide

Whether your building a kitchen, renovating, or updating your appliances – a kitchen range hood is crucial for improving the air quality and ventilation in your kitchen.

A range hood is not required by the Building Code of Australia (BCA), but is installed in most new properties – houses and apartments. Designed to capture smoke, steam, and other particles produced in cooking, a kitchen range hood will increase the value of a home and keep your kitchen cleaner, for longer. So, for new and existing properties, how much does it cost to install a range hood?

Who can install a range hood in Australia?

A range hood is an electrical appliance – it will need to be installed into your home’s electrical wiring system by a licensed electrician.

Installing a range hood generally involves electrical and ducting work, which can be extremely dangerous if not completed correctly. A licensed electrician will have the experience and knowledge to install range hoods safely, comply with local building codes, and ensure proper ventilation.

It’s important to note that in Australia some manufacturers may void warranties if the range hood is not installed by a licensed electrician. Therefore, hiring a professional to install the range hood will also ensure entitlement to warranties if any issues arise in the future.

Factors that affect range hood installation prices

Hiring an electrician to install a range hood can cost between $500 to $2,000, depending on the following factors:

Type of Range Hood

There are different types of kitchen range hoods including under-cabinet, wall-mounted, island, built-in, and downdraft range hoods. Each type of range hood has its own unique features, and some may be more complicated than others to install.

Electrical Work

Unless you’re replacing a range hood with an existing like-for-like system, installing a range hood will often require additional electrical work to link up with the home’s electrical system. The cost of electrical work varies depending on the scope of the project, such as the installation of circuits or upgrading an electrical panel.

Ductwork

A ducted range hood refers to an external ventilation system that must be connected to a duct in the wall, ceiling, or floor in order to work. This external ventilation system will help to move any smoke, odours, and grease from inside the home to outside. Installing ductwork can cost between $150 to $1,000+ depending on the complexity of the project.

Permit and/or Inspection Fees

Some Australian states may require permits or inspections for a kitchen range hood to be installed. Check with your local building council to make sure you are following the requirements for your area.

average range hood installation costs depending on the type of range hood

Types of kitchen range hoods and installation costs in Australia

As mentioned, the type of kitchen range hood will have an influence on the overall installation costs. 

Under-Cabinet Range Hoods

Under-cabinet range hoods are ideal for kitchens with limited space as they are mounted under cabinets and over a stove. Installation of an under-cabinet range hood is typically more affordable and will cost between $700 to $1,000.

Wall-Mounted Range Hoods

Wall-mounted range hoods are installed on the wall above the cooking range. These range hoods are generally easier to install, making the average cost lower at $700 to $1,000 for installments.

Island Range Hoods

Designed for kitchens with an island stove, island range hoods are mounted from the ceiling and generally require ductwork to vent outside. Island range hood installation costs will be between $500 to $1,400.

Built-In Range Hoods

Built-in range hoods are available in different sizes and styles that may require customisation to fit the space properly. For this reason, the cost of installation can be higher – costing between $1,000 and $1,500.

Downdraft Range Hoods

Downdraft range hoods work by drawing smoke and steam downward as opposed to upward like other range hood options. Costing between $1,500 to $3,000 to install, downdraft range hoods are the most expensive range hood option to install.

Cheapest type of range hood to get fitted

Wall-mounted and under-cabinet range hoods are generally the cheapest type of range hood to be fitted. Both range hoods offer different styles and sizes that can be fitted to the kitchen’s existing aesthetic and layout, with no customisation needed. 

The average cost to install wall-mounted and under-cabinet range hoods is between $700 and $1,000. The price is dependent on whether the project requires additional electrical or ducting work, and the size of the range hood. 

Most expensive type of range hood to get fitted

Downdraft range hoods are the most expensive option to get fitted. As they have specific fitting requirements, planning is essential to ensure the downdraft range hood is fitted property.

For example, downdrafts are fitted behind or beside the cooking range – which makes it impossible to use standard installation specifications. Instead, electricians must undergo previous planning to adjust and fit the downdraft range hood specific to the kitchen space to avoid improper ventilation in the future.

Depending on the amount of work needed prior to installation, downdraft range hoods cost between $1,500 and $3,000.

Do range hoods need to be serviced or require safety checks?

Servicing and safety check requirements change between residential and commercial buildings. 

Residential

The Building Code of Australia (BCA) does not have any mandatory requirements to service or safety check range hoods in residential buildings. That being said, every manufacturer will recommend how long to leave between servicing the specific range hood to optimise the ventilation system, check for any electrical issues, and keep it clean. 

Commercial

The rules are different for range hoods in commercial buildings. Under the Work Health & Safety (WHS) regulations, Australian Standards do require regular inspections, maintenance, and record-keeping documents for range hoods in commercial buildings.

Fixed fee vs. paying electrician by the hour – which is most economical?

In Australia, electricians can charge by the hour or provide a quote with a fixed fee. To get the most out of your money, it’s important to weigh up which option is the most economical to install a kitchen range hood.

A licensed electrician will generally charge between $80 to $140 an hour for their services. Initially, electricians will charge a service, or call-out, fee for their time and effort when responding to an issue – usually costing between $50 and $150. The service fee can sometimes contribute to the first 30 minutes to an hour of work.

As electricians, we can also estimate the cost of a project. Some electricians will provide estimations for free, some will charge in addition to the installation cost.

Economically, paying an electrician by the hour for a smaller job would be best. For a bigger job, however, a flat fee can ease stress and hidden costs – making it an ideal option for your wallet.

When installing a new range hood, it’s important to work with an electrician you can trust – rather than hiring the cheapest sparky on the block. Radiance Electrical are the North Shore’s leading electricians – we’ve helped hundreds of locals in the area to hook up new range hoods and other electrical projects.
