What is an RCD?
An RCD is commonly referred to as a safety switch. RCD testing is the compliance testing of a Residual Current Device that is a sensitive life-saving component of your electrical board, which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire or from a faulty electrical appliance. It also provides protection from electrical fires. RCD’s offer a level of protection and reassurance that ordinary fuses and circuit breakers cannot.
