1. A fault indicator for indicating the occurrence of a fault in an electrical conductor, comprising:

  • a housing;

    a battery;

    a fault sensor for sensing the occurrence of a fault on said electrical conductor;

    at least one light emitting diode operable from said battery and viewable from the exterior of the housing;

    a microprocessor in communication with said fault sensor to determine when a fault has occurred on said electrical conductor, to enable the supply of power from said battery to said at least one light emitting diode upon determining that a fault has occurred, to cease enabling power from said battery to said at least one light emitting diode at a predetermined time after determining that a fault occurred and to reset said fault indicator around said predetermined time; and

    inrush restraint circuitry for sensing an inrush condition on said electrical conductor.
