  • a housing;

    a battery at least partially internal to the housing;

    a display for indicating that a fault condition has occurred;

    a current sensor for sensing the load current in said conductor, and for providing a load current signal that is related to the load current;

    a data processor drawing power from the battery, and that is in communication with said load current signal from said current sensor to determine the load current in said conductor, to program the fault indicator to one of a plurality of trip settings and to determine that a fault condition has occurred when the load current exceeds the programmed trip setting.
