Switchboard Upgrade South Perth

The electrician starts by looking at the board you have now. That means the fuses or breakers, the wiring behind them, the main switch and how many circuits the house really runs.

From there the advice is plain. Sometimes a few safety switches fixed to the existing board solve the problem. Sometimes the board is too old or too full, and a full replacement is the sensible option. You should hear which one applies and why, with a price for that job alone.

A full upgrade removes the old board and fits a new one with a circuit breaker for each circuit. A circuit breaker is a switch that trips when a circuit draws too much current, and unlike a ceramic fuse it can be reset without replacing a part. Each circuit is then wired back in and labelled, so you know which switch controls the kitchen and which controls the bedrooms.

If you are adding solar, air conditioning or an EV charger, the new board is built with spare room for them, so later work does not mean another board change.

The power is off only while the old board comes out and the new one is wired in. The aim is to have it back on the same day once the new board is in.

That window stretches when the job has extras. A house with many circuits takes longer to rewire onto the new board. An old board with tired cables can need repairs before it will accept breakers. And if the meter side needs work, Western Power handles disconnecting the supply, so the timing then depends on that step as well.

It helps to plan the day around the outage. Fridges and freezers cope with a few hours without power, but a home office, a medical device or a sleep-in shift worker may need arrangements. Mention these when you ask for the quote so the electrician can plan the work around them.

The main switch cuts power to the whole house in one move. It is the first thing an electrician reaches for in a fault and the last thing switched on once the work is done.

On an older board the main switch may be missing, worn or sized for a house that ran fewer appliances. A new one is matched to the board and the incoming supply, so the whole system works as one unit.

Beside it sit the safety switches, also called an RCD (residual current device). An RCD shuts power off in a fraction of a second if current leaks, for example through a person or a damaged appliance cord. In WA, a home that is sold or newly leased needs at least two RCDs protecting power and lighting circuits, so a board without them can hold up a sale or a new tenancy.

Older boards were sometimes mounted on a panel that contains asbestos. Left undisturbed it is a low risk, but drilling, cutting or removing it is not.

If the electrician suspects the panel is asbestos, the sensible step is to stop and have it handled properly rather than drill into it. That can add a step and some time, and it is better known before the day than discovered halfway through.

An asbestos panel that is intact is not a reason to put off the upgrade. It just means the removal is planned with the right precautions.
