Surge Protection for Your Home in Perth: 6 Things to Know
Surge protection for your home is one of those things people think they have because there is a surge-protected power board behind the television. That covers one device, not the house. Here are six things to know about surge protection for your home in Perth.
1. What a surge actually is
A surge is a brief spike in voltage, far above normal, lasting a fraction of a second. Surge protection for your home exists because modern electronics are sensitive to those spikes in a way that older appliances were not, and the damage is often permanent.
2. Where surges come from
Lightning is the dramatic cause, but most surges are more mundane: switching on the electricity network, large appliances cycling, or work on nearby infrastructure. Surge protection for your home matters because the small, frequent spikes degrade equipment quietly over time.
3. Board-level versus point-of-use
There are two layers. A device installed at the switchboard provides surge protection for your home as a whole, while surge-protected boards protect individual devices. They complement each other, and relying only on the power board leaves everything hardwired unprotected.
4. What it protects
Surge protection for your home covers what a power board never reaches: the oven, the aircon, the hot water system, hardwired electronics and increasingly a home battery or EV charger. Those are also the expensive items, which is where the value sits.
5. What it cannot promise
Being honest about limits matters. Surge protection for your home reduces risk substantially, but no device guarantees protection against a direct lightning strike. It is risk reduction rather than a guarantee, and it should be described that way by anyone selling it.
6. It needs installing at the board
A whole-home device is installed in the switchboard by an electrician, which means it needs space on the board and a compatible setup. Surge protection for your home is therefore often discussed at the same time as an upgrade, when the board is open anyway.
Worth it in some homes more than others
A home full of connected devices, a home office, solar, or an EV charger has more at stake than a house with a fridge and a television. Weighing surge protection for your home against what is actually connected to it is a sensible way to decide.
Devices have a working life
Surge protection devices absorb energy, and they wear out doing it. Many have an indicator showing whether they are still functional. Checking that occasionally matters, because a device that has done its job and expired is no longer protecting anything.
It is not a substitute for safety switches
Worth being clear: surge devices protect equipment, RCDs protect people, and circuit breakers protect wiring. They do different jobs and none replaces the others. A home should have proper RCD protection regardless of whether surge protection is fitted.
Check what your insurance says
Some policies treat surge damage differently from other electrical faults, and a few offer better terms where protection is fitted. It is worth a look at your own cover before deciding, since the answer varies between insurers and can change the value of installing it.
After a suspected surge
If a storm or network event has knocked out several appliances at once, or left anything scorched, hot or smelling of burning, do not simply reset and carry on. That warrants an Emergency Electrician Perth checking the installation before everything goes back into use.
Why use a licensed electrician
Fitting surge protection for your home means working inside the switchboard, which is licensed work. A licensed electrician confirms the board suits it and installs it correctly. The state’s Building and Energy sets the requirements involved.
