Abstract:
A ground fault circuit interrupter for use on a circuit including an AC power source and a load electrically connected via hot and neutral lines, comprising a current sensor for sensing current on both the hot and neutral lines and for generating a differential current signal based on any differential between the current flowing in the hot line relative to the current flowing in the neutral line, and a switching component forming part of the circuit for opening the circuit when said differential current signal exceeds a threshold value, said switching component being a pair of MOSFET switching components which permit substantially instantaneous switching and which comprise a single channel of said interrupter, a first of said pair of said MOSFET switching components being connected in series across its drain and source to the hot line of the circuit, and a second of said pair of said MOSFET switching components being connected across its drain and source adjacent and in series with said first MOSFET switching component in the hot line of the circuit.
