Switchboard Upgrade in North Perth

Yes, in nearly every case. A rewire replaces the cable running to your power points and lights. The switchboard is where each of those circuits starts, so the board has to suit the new work.

A circuit breaker trips when a circuit draws too much current. A safety switch, also called an RCD, cuts the power quickly when electricity leaks to earth, which lowers the risk of a serious shock.

The electrician checks an old fuse board for missing safety switches and space for new protection. Connecting fresh cable to that board would leave the new work only partly protected.

The electrician looks at the board on site and confirms what it needs. Sometimes that is a full new switchboard. A newer board may only need extra safety switches. Either way, the quote sets out the scope before work starts.

Homes from the early 1900s may still carry original wiring in places. One older insulation type is Vulcanised Indian rubber, a rubber coating on the copper that hardens and cracks with age. Once it cracks, bare copper can touch timber or other wires. That is why rewiring and board work are usually planned together.

There may also be a panel behind the old fuses made from asbestos-containing board. Drilling or cutting it releases fibres, so a licensed electrician stops and has it handled safely. That can add a step to the job, and the electrician explains it on site.

Solid brick also shapes the rewire. Cable has to run through ceilings, roof spaces and floor cavities, or sit in channels cut into the brick. The route affects the labour, and labour is a large part of what drives the price.

A new board replaces fuses with circuit breakers and adds safety switches across the power and lighting circuits. The everyday result: a tripped breaker resets with a flick instead of a fuse wire swap, the safety switches cut power fast when a fault leaks to earth, and each circuit is labelled so you know what has gone off.

It also leaves spare room. Air conditioning, solar and an EV charger each need their own breaker, and they tend to arrive after the walls are closed up. A board with space for them is far easier than squeezing them into a full one later.

If the work reaches the meter side, Western Power may need to disconnect the supply, and the electrician explains how that affects timing. For work on your own circuits, the electrician isolates them and swaps the board, so the house is without power while that happens.

After installation work in WA, the contractor must give you an electrical safety certificate within 28 days. Keep it with your house papers.

If you plan to sell or lease, homes sold or newly leased in WA need at least two RCDs protecting power and lighting circuits. A new board with safety switches fits that rule.
