Switchboard Upgrade Shenton Park: Old Boards in Timber and Iron Cottages

A cottage board is usually a small panel on a verandah wall or in a hallway, with a few ceramic fuses or a handful of older breakers. It was sized for a time when a house ran lights, a radio and an iron. Today it carries a fridge, a microwave, a toaster, a heat pump and sometimes a car charger.

An electrician starts by opening the board and looking at the wiring behind it. They look at the age and condition of the cables, how many circuits there are and whether any are overloaded. Then they recommend the smallest job that fixes the problem. Sometimes that is adding safety switches. Sometimes the whole board needs to come out.

Timber framing changes how the work is done. The electrician takes care with cable runs through wall cavities and roof spaces, because old cable insulation can be brittle. The new board goes on a fresh backing, and each circuit is labelled so you know what every switch controls.

The change you notice first is how the board copes with a busy kitchen. A circuit breaker is a switch that trips when a circuit draws too much current. Unlike a ceramic fuse, you reset it by flicking it back on, with no fuse wire to replace in the dark. If the microwave and toaster overload the same circuit, the electrician can check whether a separate circuit is needed alongside the new board.

The second change is protection. An RCD, also called a safety switch, cuts the power quickly when current leaks to earth, which lowers the risk of a serious electric shock. Old fuses do not do this job at all.

A new board also leaves spare room. If you are planning solar, air conditioning, an EV charger or an extension at the back of the cottage, the board can be sized for those circuits now, so you are not paying to rework it later.

Old boards from the era of timber and iron houses sometimes have a flat backing panel that contains asbestos. Suspected asbestos should be assessed before work starts and must not be drilled, cut or disturbed, so an electrician who suspects it stops and arranges proper handling before going further.

Fire risk is the other reason an old board matters. Loose connections, overheated fuse holders and cables that have been patched over the years can run hot inside a wall. Burn marks, a smell of hot plastic, buzzing or a switch that is warm to touch are signs that the board needs attention soon.

If you see smoke or flames, call 000 straight away.

The power is off while the old board comes out and the new one goes in, and the electrician confirms the finish time once they have seen your board. In a timber cottage most of the time goes on the cable runs behind the board. A few circuits with tidy cables go quicker than an extended home with newer circuits added to the original wiring.

When the work reaches the meter side of the supply, Western Power may need to disconnect it first, which can affect when the job is booked.

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

In WA, any home that is sold or newly leased needs at least two RCDs protecting its power and lighting circuits. An original cottage board may have none, so a pre-sale or pre-lease job often starts with fitting them. If the board is also old and crowded, replacing it in the same visit can cost less than doing two separate jobs.
