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 that 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.
Layered Surge Protection for Homes with Solar
Many modern Brisbane homes now require layered surge protection, especially when solar is installed.
This means:
- 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 systems
- 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
