In Australia, RCD testing is a legal requirement for all electrical contractors. This type of testing is designed to protect people and property by ensuring that all electrical circuits are safe. RCDs (residual current devices) are essential in preventing electrocution and fires caused by faulty electrical wiring.

Testing RCD’s involves a simple process of connecting an RCD tester to the circuit and measuring the current flowing through the device. If the current is above the specified level, it means that there is a problem with the circuit and it needs to be repaired or replaced immediately. RCD testing should be carried out on all circuits at least once every six months, and more often if they are subject to high levels of use.
