CA 2184652

An electrical extension cord with built-in safety protection includes an electrical cable formed with insulated phase, neutral and ground conductors surrounded by abraided sensing shield. An electrical receptacle is electrically connected to the cable at first ends of each of the phase, neutral and ground conductors, and theshield is electrically connected to the ground conductor. A ground fault circuitinterrupter (GFCI) is electrically connected to the cable at second ends of the phase, neutral and ground conductors, within which the ground conductor is electrically coupled to the shield through a predetermined impedance such that leakage current is collected by the shield and detected by the GFCI.
