RCDs are an extremely effective form of shock protection The main incoming cable, then it must have allĬircuits protected by an RCD (because u mite not be able to get If a house has an earth system connected to an earth rod and not Through phase and neutral detect by -RCD and trip the Any mismatch between two currents flowing The amount of current flows through the phase (line) should It trips the circuit when there is earth fault current. Phase (line) and Neutralboth wires connected through RCD.
