Do You Actually Need a Safety Switch Upgrade?

If your home still has just one safety switch covering the whole switchboard, you’re not alone — a lot of older homes on the Mornington Peninsula were wired well before current safety standards existed.

A safety switch (also called an RCD, or residual current device) is what cuts the power in a fraction of a second if it detects current leaking somewhere it shouldn’t — like through a person. It’s one of the simplest, cheapest pieces of electrical safety equipment there is, and it’s the difference between a nasty shock and a fatal one.

The problem with older boards isn’t that they don’t have a safety switch at all — most do. It’s that one safety switch often covers every circuit in the house. If a fault trips it, everything goes dark at once: lights, fridge, everything. Modern switchboards split circuits across multiple safety switches, so a fault in one area doesn’t take out the whole house.

An upgrade usually means fitting a new switchboard with safety switches on every circuit, rather than one shared across the lot. It’s not a big job compared to most electrical work, and it’s one of the highest-value safety upgrades you can make to an older home.

If you’re not sure what’s behind your switchboard cover, it’s worth a quick look — or a quick call. Get in touch and we’ll tell you straight whether an upgrade makes sense for your place.
