What a safety switch does

It cuts power in milliseconds when it detects electricity leaking to earth — through a person, for example. It is the difference between a scare and a tragedy.

Test them quarterly

Press the TEST button — power should cut instantly. If it does not, the device is not protecting you and needs attention now.

One shared switch is not enough

Older homes often have one safety switch covering a few circuits, or none. Per-circuit RCBOs are the modern standard.

What an electrical safety check finds in Adelaide

Electrical problems almost never announce themselves. Deteriorated insulation, undersized circuits, dodgy past DIY and tired switchboards sit quietly behind the walls until something trips, smells or stops working — often at the worst possible time. A proper inspection is how you find that before it finds you.

A real safety check isn't a glance at the board. It's testing the safety switches, checking earthing and bonding, looking at the condition of visible wiring and accessories, and flagging non-compliant work from previous owners or trades. You come away knowing exactly where the house stands.

When a safety inspection is worth it

• Before buying an older home — know what you're inheriting
• Rentals, so landlords meet their safety obligations
• After noticing tripping, flickering or warm fittings
• Homes that have had unknown DIY or trade work
• Properties that haven't been checked in 10+ years
• Before a renovation, to plan the electrical properly

A few hundred dollars of inspection routinely saves people from a five-figure surprise after settlement, or a fault that becomes a fire. It's cheap certainty about the most hidden system in the house.
