A residual current device (RCD), or safety switch, protects you from the most frequent cause of electrocution – a shock from electricity passing through the body to the earth. It can also provide some protection against electrical fires.
RCDs are electrical safety devices designed to immediately switch off the supply of electricity when electricity leaking to earth is detected at harmful levels. They offer high levels of personal protection from electric shock.
RCDs must be tested regularly by a competent person to make sure they are working effectively.
