Coastal Test & Tag delivers RCD testing in Coffs Harbour for workplaces, worksites and homes that need to confirm their safety switches will trip within the limits set by Australian Standards. Whether you've got fixed RCDs in a switchboard, portable RCDs on tools or RCDs built into power boards, we can test the lot in the one visit.
An RCD, or residual current device, cuts power the moment it detects current leaking to earth, which is what stops a live wire from becoming a fatal shock. The faster it trips, the smaller the shock, so trip-time is the number that actually matters.
Our technicians use a calibrated RCD tester to measure the trip time at the rated current, confirm the device is operating within AS/NZS 3760 limits, and tag each switch with the result and the next test due date. Slow or failed devices are flagged on the spot.
We are based in Coffs Harbour, but we look after the whole Mid North Coast and further afield, down to Newcastle and even out to Western NSW.
We often try to run our RCD tests in conjunction with our regular test and tag rounds, and if a worn lead or damaged plug turns up along the way our team can handle the repair on the same visit rather than tagging it out.
