Abstract:
A fault indicator for indicating the occurrence of a fault in an electrical conductor and for indicating an overload condition on said electrical conductor, said fault indicator comprising:a housing; a fault sensor for sensing the occurrence of a fault on said electrical conductor; a fault display for indicating that a fault has occurred, said fault display viewable from the exterior of the housing; a current sensor for sensing the current load in said conductor; an overload indicator for indicating that the current load on the conductor is above a predetermined overload value but less than the current load that causes the fault sensor to determine that a fault has occurred, said overload indicator viewable from the exterior of the housing, and a microprocessor in communication with said fault sensor to determine when a fault has occurred on said electrical conductor and to activate the fault display to a fault displaying condition, in communication with said current sensor to determine if the current load in the electrical conductor is above the predetermined overload value, to activate the overload indicator to an overload displaying condition if the current load is above the predetermined overload value, and to cease activating said overload indicator at a predetermined time after determining that the current load is below the predetermined overload value.
