7 signs your switchboard needs upgrading

Your switchboard is the one part of the house that protects everything else in it. When it's out of date, the protection either isn't there or doesn't work fast enough. Here's what to look for, and what's genuinely urgent versus what can wait.

1. Ceramic fuses instead of switches

If you replace a fuse by pulling out a porcelain holder and rewiring it, your board predates modern safety standards by decades. Rewireable fuses don't protect people from electric shock, only circuit breakers with RCD protection do that. This is the big one.

2. No safety switches (RCDs)

Safety switches detect current leaking to earth, through a faulty appliance, damaged cable, or a person, and cut power in under 30 milliseconds. Victorian rentals legally require them. Owner-occupied homes often still don't have them, and it's the single cheapest life-safety upgrade available.

3. Breakers that trip regularly

An occasional trip is the system doing its job. A breaker that trips weekly is telling you something: an overloaded circuit, a failing appliance, or moisture in an outdoor point. Repeatedly resetting it without finding the cause is the electrical equivalent of taping over a warning light.

4. Warm or discoloured powerpoints and switches

Heat means resistance, and resistance at a connection means arcing. Brown scorch marks around a socket, or a plate that's warm to touch, needs looking at promptly, this is how electrical fires start.

5. Lights dimming when appliances start

If the lights dip when the kettle, aircon or washing machine kicks in, the supply or the board is struggling to deliver. Sometimes it's a loose connection (fixable), sometimes it's genuinely undersized supply.

6. No room for more circuits

Planning solar, a heat pump, induction cooking or an EV charger? Every one needs its own circuit. If the board is full, you're upgrading anyway. And doing it once, planned properly, beats three separate visits.

7. It's over 25 years old

Boards installed before the early 2000s generally predate current RCD requirements. If nobody's touched yours since, an inspection is cheap peace of mind even if nothing's obviously wrong.

What does a switchboard upgrade cost?

A typical domestic board replacement runs $1,100 to $2,200 inc GST depending on the number of circuits, whether the enclosure needs replacing, and how tidy the existing wiring is. Older homes where the cabling has been added to over decades sit at the top of that range because the work is genuinely more involved.

What that gets you: individual circuit breakers, RCD protection on every circuit, a labelled and legible board, capacity for what you're planning next, and a Certificate of Electrical Safety.

Which of these are urgent?

Burning smells, scorch marks, hot fittings and sparks. Call someone today. Ceramic fuses and missing safety switches, important, but you can plan it properly rather than panic. Everything else, get it assessed and make an informed decision.
