Residual Current Device (RCD) Testing Services
Residual Current Devices, commonly known as safety switches, are one of the most important electrical safety devices in any workplace. They detect imbalances in electrical current and disconnect the power within milliseconds, preventing potentially fatal electric shocks. Aussie Test & Tag provides professional RCD testing to ensure your safety switches are working correctly when you need them most.
Under Australian/New Zealand standards AS/NZS 3760 and AS/NZS 3000, regular testing of RCDs is mandatory in all workplace environments. Our qualified technicians carry out both push-button and time-current testing to verify that each RCD operates within the required trip time and current thresholds.
Our RCD Testing Process
Our RCD testing service includes the following:
- Visual inspection of the RCD unit for damage, corrosion or incorrect installation
- Push-button test to verify the mechanical trip mechanism operates correctly
- Time-current trip test using a calibrated RCD tester to measure disconnection time
- Testing at both rated and half-rated trip currents as required by AS/NZS 3760
- Verification that the RCD disconnects all active conductors on trip
- Labelling with test date, results and next due date
- Detailed digital report of all RCD test results
How Often Should RCDs Be Tested?
RCD testing frequency depends on the operating environment. Fixed RCDs in workplaces should be tested every 12 months using the push-button method, with full time-current testing conducted annually. Portable RCDs used on construction sites require testing before each day of use. Our team will help you establish the correct testing schedule for your workplace.
