As we settle into 2025, there’s never been a better time to talk about home safety — particularly when it comes to your electrical system. Whether your home is decades old or only a few years new, one essential device that can protect your family and property is the safety switch.
A safety switch, also known as a Residual Current Device (RCD), is designed to cut off electricity within milliseconds if it detects a fault — like a person receiving an electric shock or a live wire coming into contact with a conductive surface.
Unlike circuit breakers, which are designed to protect appliances and wiring from overloads or short circuits, safety switches are designed to protect people.
No safety switch in place is a big contender for house fires!
Here’s why:
Loose connections, overloaded power boards, or even damaged cords are all common in homes — especially older ones.
A normal circuit breaker will not detect a fault current — so if an appliance fails or a cable is damaged, the breaker may not trip.
That means electricity continues flowing, creating heat, sparks, and eventually fire — especially when left undetected for long periods.
This is why so many electrical house fires happen overnight or when people are away from home.
If your home was built before the early 2000s, there’s a good chance your switchboard:
Has minimal or no safety switches
Was designed for far fewer appliances and power demands than we use today
An upgrade ensures your home can handle everything from dishwashers to air fryers safely.
Modern safety switches react within 0.03 seconds of detecting a fault. That’s fast enough to potentially save a life, and certainly fast enough to prevent an electrical fire from starting.
If you’re planning a renovation or selling your property, Queensland law now requires safety switches to be installed on all final sub-circuits in residential homes. Upgrading now saves hassle later.
Whether it’s kids using hair dryers in the bathroom, a powerboard full of devices under a desk, or heaters running in winter — safety switches give you confidence that your family is protected.
