Switchboard Upgrades Keswick: Replace an Old Board Safely

A board needs replacing when it can no longer protect the home or carry the load you put on it. One loose breaker is often a repair. A board that is crowded, scorched, warm to the touch or built around ceramic fuses is usually past repairing.

Circuits that keep tripping are the first sign. A breaker cuts out because something is wrong. It might be an overloaded circuit, a faulty appliance or a worn board, and the electrician tracks down which one.

A missing safety switch is the second. A safety switch cuts the power very quickly when current leaks, which lowers the risk of a serious shock. Boards that only have old fuses often lack them.

No spare room is the third. Solar, a battery, an EV charger, ducted heating and induction cooking each need their own circuit. A full board has nowhere to put them.

A burning smell, buzzing or hot power points near the board is more urgent. If you see smoke or flames, call 000. Otherwise switch off what you safely can and get an electrician to look at it promptly.

The electrician removes the old board, fits a new one and rewires each circuit into it. New breakers go in for each circuit, along with safety switches, and the board is laid out with spare space for what you add later.

Before starting, the electrician looks at the existing wiring, the meter box and the load of the house. That tells them what size of board you need and whether any circuits are in poor shape. Old wiring behind the board sometimes needs attention too, and the electrician tells you about it before the work, not after.

The power goes off while the board is swapped, so a fridge, a work-from-home setup or medical equipment is worth mentioning early so the shutdown can be managed around it.

In South Australia this work needs an electrician registered with CBS and working under an Electrical Contractor's Licence. After the upgrade the electrician lodges a Certificate of Compliance, and you should receive your copy within 30 days.

Older boards were sometimes mounted on backing panels that contain asbestos. It is not dangerous while it sits undisturbed, but cutting or drilling it releases fibres. If the backing may contain asbestos, it is treated as asbestos and removed intact under the handling rules, not cut or drilled on site.

Old ceramic fuses and the board they came from are also removed and disposed of as part of the job. If the backing looks suspect, the electrician stops and says so before anything is cut.

Cost depends on the size of the board, how many circuits it carries, the state of the wiring behind it and how easy the meter box is to reach. A small home with a tidy board is a smaller job than a house with several additions and tangled wiring.

You get a clear price before work starts. A quote sets the agreed scope, though a hidden fault behind the old board can still change the job, and the electrician tells you if that happens. Adding safety switches and spare capacity for solar or an EV charger at the same visit usually costs less than coming back later.
