RCD / Safety Switch
Professional RCD and safety switch testing to ensure life-saving protection works correctly. Compliant trip-time testing across Melbourne and Victoria.
A residual current device (RCD) or a residual current circuit breaker (RCCB) commonly know as a safety switch is designed to isolate power when it detects an in-balance commonly of 30 mA (milliamps) between the active and neutral conductor.
These in-balances are commonly caused by current leakage through earth. This leakage can be caused via a faulty appliance or through the body of a person accidentally touching an energized piece of equipment.
RCD/RCCB's are designed to disconnect power to the circuit when a difference of 30mA is detected. This disconnection or tripping of these breakers should happen without due delay, if the RCD takes too long to trip the results could be fatal.
Testing RCD's using the correct equipment ensures that the protective device will do its job within the correct allowable time frame, if it is required to do so.
Our technicians test both portable and fixed RCD devices using calibrated testing instruments that verify trip times are within the allowable safety limits. Each device is tested at multiple current levels to confirm reliable operation under real fault conditions.
Regular RCD testing is a critical part of workplace electrical safety. Australian standards recommend that portable RCDs be tested every three months in hostile environments. Our team provides detailed test reports and barcode tagging for every device tested, ensuring full compliance documentation for your records.
It is important to note that pressing the test button on an RCD only confirms the mechanical trip mechanism works — it does not verify that the device will trip within the required time frame. Professional testing with calibrated instruments is the only way to confirm your RCD will provide adequate protection in a real fault situation.
