1. A circuit interrupting device comprising:

  • a first electrical conductive path having two or more conductors capable of being electrically connected to a source of electricity;

    a second electrical conductive path having two or more conductors capable of conducting current to a load when electrical continuity between said first and second electrical conductive paths is made;

    a fault detector coupled to monitor voltage and/or current in the first and/or second electrical conductive paths and produce a fault signal when a fault is detected;

    a first relay interposed between said first and second conductive paths; and

    a second relay interposed between said first and second conductive paths having its current carrying path coupled in parallel with the current carrying path of said first relay.
