Abstract: A power distribution box is provided with built in surge suppression capabilities that can be service without interrupting power to downline circuits powered from the power distribution box. A socket is wired directly to the busses supplying power to the circuit breakers in the power distribution box. The socket is designed to accept a surge suppression module that can be removed and replaced while the electrical connections in the socket are "hot." To prevent accidental electrocution the electrical contacts of the socket are place below the surface of the socket. Additionally, the stab-in connectors of the socket and the corresponding stabs of the surge suppression module are arranged in such a way as to ensure that the module is properly polarized when inserted into the socket.
