Protecting Your Home Against Power Surges
Power surges are one of the most common causes of electrical damage in Brisbane homes. From severe storms and lightning to heat-related grid overloads and transformer faults, voltage spikes can enter your home without warning and quietly damage appliances, solar systems, and wiring.
At Precision Electrical & Air, we install professional surge protection designed to protect your home at the switchboard, not just at the power point.
What Causes Power Surges in Brisbane?
Brisbane’s electrical network is exposed to a wide range of surge events, including:
- Electrical storms and nearby lightning strikes
- Extreme summer heat causing grid overloads and brownouts
- Power being restored after outages
- Transformer failures or explosions
- Vehicle accidents damaging power poles or substations
- Voltage instability in areas with high solar penetration
Even small or repeated surges can shorten the lifespan of air conditioners, televisions, computers, and solar inverters over time.
Why Plug-In Power Boards Aren’t Enough
Many homes rely on plug-in surge-protected power boards. While these offer limited protection for individual devices, they do not protect your entire electrical system.
Surges often enter through:
- The main power supply
- Solar inverter connections
- Sub-boards or long cable runs
Without switchboard-level protection, surge energy can still travel through your wiring and damage fixed appliances and safety systems.

Professional Surge Protection at the Switchboard
We install surge protection devices (SPDs) directly into your switchboard, where they can respond instantly to voltage spikes.
When a surge occurs, the surge arrestor diverts excess voltage safely to earth before it reaches your circuits. This happens in microseconds, far faster than circuit breakers or safety switches can respond.
Homes with solar need layered protection:
- One surge arrestor protecting the incoming grid supply
- A separate surge arrestor protecting the solar inverter supply
Surges don’t just come from outside the home — solar inverters can also introduce voltage spikes during switching, shutdowns, or grid disturbances. Installing protection on both sides ensures your home and solar equipment are properly shielded.

What Surge Protection Helps Protect
A properly installed surge protection system helps protect:
- Air conditioning systems
- Televisions and home entertainment
- Solar inverters and batteries
- Computers and networking equipment
- Kitchen appliances and refrigeration
- Safety switches and smart home systems
It also reduces nuisance tripping and helps maintain stable power throughout the home.
Do Surge Arrestors Need Maintenance?
Yes. Surge arrestors are sacrificial devices: they absorb damage so your equipment doesn’t.
After major storms or surge events, they may no longer provide protection. Many devices include a visual indicator to show when replacement is required.
We recommend:
- Inspection after severe storms
- Checks during switchboard servicing or electrical safety inspections
- Replacement when indicators show the device has been exhausted

What Our Electrical Customers Are Saying
Surge Protection Questions, Answered
01Why are power surges common in Brisbane homes and businesses?
Power surges are common in Brisbane due to frequent electrical storms, extreme summer heat, grid overloads, and power being restored after outages. Transformer faults and car accidents damaging power poles can also send sudden voltage spikes through the local network.
02Can Brisbane storms damage appliances even if the power doesn’t go out?
Yes. Many surge events happen without a full blackout. A nearby lightning strike or grid disturbance can send a voltage spike through your wiring in milliseconds, damaging air conditioners, TVs, solar inverters, and electronics without cutting power completely.
03Does surge protection help with brownouts and heat-related power issues?
Yes. During Brisbane heatwaves, high demand on the grid can cause unstable voltage and brownouts. Surge protection devices help limit voltage fluctuations and protect sensitive equipment from damage caused by repeated power instability.
04Is surge protection recommended for homes with solar in Brisbane?
Yes. Homes with solar systems in Brisbane are at higher risk of surge damage because surges can enter from both the grid and the solar inverter. Installing surge protection on both the mains supply and the solar side helps protect inverters, batteries, and connected appliances.
05Do surge protection devices need replacing after Brisbane storms?
They can. Surge protection devices absorb damage to protect your electrical system. After major storms or surge events, they may no longer provide protection and should be checked by an electrician. Many devices include indicators showing when replacement is required.
