R.C.D. Testing

What are RCD'S ?

An RCD is an acronym for Residual Current Device. They can sometimes be called ELCB's (Earth Leakage Circuit Breakers) or Safety Switches.

An RCD monitors the flow of electricity through the circuit it is attached to. Should any abnormalities associated with the delivery of an electric shock or fatal electrocution be detected by the RCD, the unit will shut off the power to the circuit immediately to minimise injury.

An RCD is a life saving device, but it does not completely eliminate the risk of electric shock. It must be tested to ensure it is working within the safety standards.

What is an RCD test ?

RCD testing is the process of safely "tripping" your RCD to ensure it will operate quickly should there be an electrical incident. This is also known as safety switch testing. Your RCD is designed to trip, or switch off all the power to that circuit. Australian and New Zealand standards detail the maximum "trip times" for various RCD's and the competent technician testing your RCD will be able to determine whether your RCD is tripping quickly enough. The quicker a RCD trips, the smaller the electric shock sustained by an individual.

Push button testing of your RCD is also required under Australian Standards on a 6 monthly basis.
