Residual Current Device. Protects the user against short circuit (earth faults) and earth leakage caused by damaged cable or faulty equipment. A RCBO is a combined MCB and RCD, protecting against earth leakage/short circuit and overload.
Residual Current Device. A type of fuse which monitors the flow of electrical current through the live and neutral wires of a circuit. When an RCD detects an imbalance caused by earth leakage, it cuts off the supply of electricity as a safety measure.
Residual Current Device. A safety device (a modified circuit breaker), usually installed within a distribution board which monitors the circuit that is is serving. In the event of a earth fault or "earth leakage" contacts will open and the supply will be isolated. Used to enhance protection where the adequacy of the earth return path may be suspect.
Residual Circuit Detector
Residual Current Device. This device is designed to detect low current leakages to earth and trip the mains power to the cable or machine. If your home is not protected by one of these and you use mains electricity to cut the lawn, they are a must.
Residual Current Device. A safety device designed to break the electrical circuit in the event of a fault or leakage.
Residual Current Device, a protective device on an electric circuit.
Residual Current Device. Part of the motorhome's electrical system which will 'trip' if there is a fault
