This is one of those jobs nobody thinks about until either something goes wrong or someone tells them they should. Here's how to actually answer the question for your own house, rather than guessing.
The Two-Minute Check
Open your switchboard and look at what's actually in there.
- Round ceramic fuse holders, the kind with a wire or fuse element inside — that's the old system, and it's the clearest single sign an upgrade is worth considering.
- No switch labelled "safety switch," "RCD," or with a "test" button — if you can't find one, you probably don't have one, regardless of how modern the rest of the board looks.
Either of those on their own is worth a conversation. Both together means it's overdue.
Why the Safety Switch Part Matters More Than People Think
A fuse or circuit breaker protects your wiring — it stops a circuit from overheating and starting a fire. A safety switch protects people — it cuts power in a fraction of a second if it detects current leaking somewhere it shouldn't, which is what actually prevents electrocution. You can have a perfectly good set of modern circuit breakers and still be missing this specific protection if the board predates it.
Signs Beyond the Visual Check
- Fuses that blow more than they used to — not a coincidence, usually a sign the board's being asked to do more than it was built for.
- Adding a higher-load appliance — an EV charger, a heat pump, a second air conditioner — and wondering if the board can actually take it.
- The board looks visibly old, scorched, or has been patched over time with mismatched parts.
- You're renting the property out — safety switches are a compliance requirement for rental properties in Victoria, not just a nice-to-have.
What the Upgrade Actually Involves
A standard upgrade replaces the old board with a modern one fitted with circuit breakers and safety switches, sized for what the property actually needs — including headroom for anything you're planning to add later. Power's off to the property for part of the day, and it's usually done in one visit.
