Install at least two residual current devices to stay safe

A residual current device (RCD) is a safety switch that helps protect you and your family.

When an RCD detects a problem with your power supply, it switches the power off within 10 to 50 milliseconds to prevent electric shock.

Under RCD regulations, all residential homes sold or leased in Western Australia must have a minimum of two RCDs protecting all power point and lighting circuits.

All RCDs have a test button that should be pressed every three months. Pushing the test button simulates a fault and indicates whether or not the RCD is operating correctly. Electric clocks and timers will require resetting after each test.

Report any electrical incidents or faults to Horizon Power immediately on 13 23 51.
In an emergency situation, call 000.

 

Electrical inspectors monitor homes which are sold or leased to ensure compliance with the regulations. Breaches attract penalties of up to $15,000 for individuals and up to $100,000 for body corporates.

If you own a residential property and do not intend to sell or lease it, you are not required to have RCDs installed. However, Horizon Power strongly recommends that you consider this potentially life-saving investment.

Remember to use a licensed electrical contractor when installing new or additional RCDs.
