Residual Current Devices (RCDs), commonly known as safety switches, are life-saving devices that protect people from electric shocks and prevent electrical fires. They monitor the flow of electricity through circuits and immediately cut off power if they detect leakage caused by faults or accidents.
Why RCD Safety Switches Are Essential
- Protect People: RCDs safeguard against electric shocks by disconnecting power within milliseconds of detecting an issue.
- Prevent Fires: By stopping current leakage that could lead to overheating, RCDs reduce fire risks.

FAQ – RCD Safety Switch Installation
An RCD (Residual Current Device), also known as a safety switch, is a life-saving device that continuously monitors the flow of electricity in your circuits and instantly cuts off power if it detects leakage or a fault, protecting against electric shocks and reducing the risk of electrical fires. Installing RCDs is crucial for ensuring the safety of occupants in both homes and businesses.
Yes, under current Victorian regulations and the AS/NZS 3000:2018 Wiring Rules, RCD safety switches are mandatory on all final sub-circuits in new domestic and residential installations, as well as during switchboard upgrades or alterations to existing circuits. Rental properties and homes for sale must also comply with these requirements to ensure comprehensive protection.
Australian standards require at least one RCD for every final sub-circuit, which typically means a minimum of two RCDs for most homes—one for power circuits and one for lighting circuits. However, more may be needed depending on the number of circuits and appliances in your property. A licensed electrician will assess your switchboard and install the correct number and rating of RCDs to ensure full compliance and optimal safety.
RCDs should be tested every three months using the built-in test button (marked ‘T’) to confirm they trip immediately and restore power safely. Regular professional inspections and maintenance are also recommended to ensure ongoing effectiveness and compliance with safety regulations.
