An electrical apparatus comprises an earth input (10a) for connection to an earth wire (10) of an electrical supply from a distribution network, an earth interface for providing an earth connection from the earth input (10a) to an appliance (2') and current sensing means (40) for sensing a current flow through the earth input (10a). The electrical apparatus further comprises earth-wire disconnection means (48) for disconnecting the earth interface from the earth input (10a) when a sensed current flow through the earth input (10a) satisfies an earth-wire disconnection condition and live-wire disconnection means (42) for initiating a disconnection of a live wire (4) of the electrical supply to the appliance (2') before or at the same time as the disconnecting of the earth interface.
