- We Fully Guarantee All Work
There’s no warning with a power surge – suddenly an instant your everything is operating like usual and the next appliances are hit with a voltage that can inflict harm. Furthermore it is not merely the storms and the lightning. As simple as a restart of a power source following an interruption or the activation of a huge appliance might introduce a sudden burst of power through the wiring of the household.
At Stuart Johnston Electrical, we install surge protection across Wollongong and the Illawarra, so you’re never the one explaining to your insurer why half the house stopped working overnight.
Electrical surge protection is a set of devices, fitted at your switchboard and (if needed) at individual power points, that catch a voltage spike the moment it happens and steer the excess current away before it fries anything.
Here’s what usually causes a surge in the first place:
Honestly, it’s usually your own appliances doing the damage, not the weather. Your switchboard works harder than you’d think.
A surge only needs a split second to wreck something expensive:
A proper surge protector installation follows a clear process:
No guessing – everything’s sized to your actual home, not a generic box off a shelf.
We provide a range of surge protection solutions, from whole-home protection and point-of-use devices to solar and EV protection, switchboard upgrades, fault finding, testing and compliance checks.
If you’re concerned about power surges or protecting sensitive equipment, contact Stuart Johnston Electrical today for professional advice and surge protection solutions.
If you’ve got solar, this matters even more — inverters are pricey, sensitive, and sitting right on your roof.

No – safety switches protect people from shocks, not appliances from voltage spikes. You need both.
Not at all. Most inverter manufacturers actually recommend surge protection, since inverters are one of the most exposed parts of your system.
Usually 5–10 years, though one big surge can use up the protection in a single hit. Worth getting checked if you’re not sure.
No, but any home on the grid benefits from it – it’s cheap insurance against an expensive problem.
Nope. Most surges come from inside your own home – appliances switching on and off, grid rerouting, that sort of thing.
A power surge can happen without warning. Contact us today to make sure your home is protected before it does.
