Switchboard Upgrade Subiaco: Older Homes, Clear Quotes

The electrician starts by looking at what your board does now. They note how many circuits it runs, whether the wiring behind it is in good shape, and how much load the house puts on it.

Then they recommend the smallest job that fixes the problem. Sometimes that is a few safety switches added to a board that is otherwise sound. Other times the board is full, cracked or built around ceramic fuses, and a new one makes more sense.

A new board uses a circuit breaker for each circuit. A circuit breaker is a switch that cuts power when a circuit draws too much, and you flip it back on instead of rewiring a fuse. Safety switches, also called RCDs (residual current devices), cut the power quickly when they detect electricity leaking, which lowers the risk of a serious shock.

If an electrician has told you the whole board must go, a second look at the board is reasonable. A clear explanation of why repair will not hold should come with the quote.

Often it can. An older house tends to sit at the higher end because the work behind the board takes longer than the board itself.

Old wiring may need extra time to reconnect neatly. Cables can be short, brittle or run in a way that does not suit a modern layout. Circuits that were added over the decades may be hard to trace, and each one has to be identified and labelled before it goes onto a breaker.

A newer home with tidy cabling is usually quicker. That does not make an older house a bad candidate. It means the quote should show what is being done to the wiring as well as the board, so you can see where the money goes.

Four things move the number most. The first is how many circuits the board must carry, since each one needs its own breaker. The second is the condition of the existing wiring. The third is whether the board must move, for example out of a cramped cupboard. The fourth is how much spare room you want for future circuits.

Planning for solar, air conditioning or an EV charger now is cheaper than reopening the board later. A good quote lists these items separately and states the total before anyone touches the board.

Selling or leasing is another reason people upgrade. In WA, homes that are sold or newly leased need at least two RCDs protecting power and lighting circuits, and an old fuse board often cannot take them.

A board from an earlier era may have a backing panel that contains asbestos. Its condition is hard to judge by eye, so a suspect panel is best left alone, with no opening, drilling or sanding. A qualified electrician stops work and has it assessed first.

If the panel does contain asbestos, a licensed asbestos removalist deals with it safely before the electrical work carries on. Your quote should say if that is likely, so you know the plan from the start.

Your quote should say roughly how long the power will be off for your house. Extra wiring work, asbestos or a disconnection on the meter side can all stretch the time.

If the work reaches the meter side, the supply may need to be disconnected through Western Power, and your electrician will explain whether that applies to your property.

After installation work in WA, the contractor must give you an electrical safety certificate within 28 days. Keep it with your house papers, because a buyer, tenant or insurer may want to see it.
