A circuit for powering a load, comprising: an output connector adapted for connecting the circuit to the load; a first relay (22A 1,22A 2) selectively connecting the output connector to a source of AC power, the first relay (22A 1,22A 2) being responsive to a disabling signal to disconnect the output connector from the source of AC power; a first latch adapted to maintain a first fault signal once emitted until it receives a rearm signal; and a logic combiner adapted to generate the disabling signal when it receives at least one of the first fault signal and a second fault signal; characterized in that the circuit further comprises: a first sensor adapted to sense a level of power delivered to the load via the output connector; a first detector adapted to: receive the sensed power level from the first sensor, and emit the first fault signal when the sensed power level exceeds a fixed power limit; and a controller adapted to: receive the sensed power level from the first sensor, emit the second fault signal when the sensed power level exceeds a configurable power threshold, receive a user command to rearm the circuit, and in response to receiving the user command, emit the rearm signal and cease the emission of the second fault signal. an output connector adapted for connecting the circuit to the load; a first relay (22A 1,22A 2) selectively connecting the output connector to a source of AC power, the first relay (22A 1,22A 2) being responsive to a disabling signal to disconnect the output connector from the source of AC power; a first latch adapted to maintain a first fault signal once emitted until it receives a rearm signal; and a logic combiner adapted to generate the disabling signal when it receives at least one of the first fault signal and a second fault signal; characterized in that the circuit further comprises: a first sensor adapted to sense a level of power delivered to the load via the output connector; a first detector adapted to: receive the sensed power level from the first sensor, and emit the first fault signal when the sensed power level exceeds a fixed power limit; and a controller adapted to: receive the sensed power level from the first sensor, emit the second fault signal when the sensed power level exceeds a configurable power threshold, receive a user command to rearm the circuit, and in response to receiving the user command, emit the rearm signal and cease the emission of the second fault signal. a first sensor adapted to sense a level of power delivered to the load via the output connector; a first detector adapted to: receive the sensed power level from the first sensor, and emit the first fault signal when the sensed power level exceeds a fixed power limit; and receive the sensed power level from the first sensor, and emit the first fault signal when the sensed power level exceeds a fixed power limit; and a controller adapted to: receive the sensed power level from the first sensor, emit the second fault signal when the sensed power level exceeds a configurable power threshold, receive a user command to rearm the circuit, and in response to receiving the user command, emit the rearm signal and cease the emission of the second fault signal. receive the sensed power level from the first sensor, emit the second fault signal when the sensed power level exceeds a configurable power threshold, receive a user command to rearm the circuit, and in response to receiving the user command, emit the rearm signal and cease the emission of the second fault signal.
