Choosing a safety switch for your home
Safety switches detect small amounts of constant electrical fault current leaking to earth and quickly switch off the electricity, minimising electric shock and reducing the risk of fire.
Safety switches wired into power and light circuits give reliable protection against serious shock. Other equipment, apparatus and circuits of an electrical installation may not have safety switch protection.
There are three types of approved safety switches.
Switchboard safety switches provide protection on electrical circuits connected to it throughout the house, and for those electrical appliances and extension cords connected to earth leakage protected power points.
Power point safety switches that replace an existing power point, protect extension cords and electrical appliances plugged into the outlet, and the electrical wiring and power points downstream from the safety switch on the same circuit.
Portable safety switches protect portable electrical appliances and extension cords plugged into the safety switch. If using power tools or electrical appliances outdoors that are not protected by a switchboard or power point safety switch, these safety switches are essential.
