Abstract

The aircraft applicable ground fault circuit interrupter interrupts a circuit when a current imbalance is sensed. The circuit interrupter includes a power supply, a sensor for sensing a current imbalance at the line side of the circuit, a logic controller, and a power controller. The power supply provides power to the sensor, logic controller, and the power controller. The logic controller receives input from the sensor, and the power controller receives input from the logic controller, and interrupts power to the load side of the circuit when the sensor senses a current imbalance. Power interruption due to a sensed current imbalance is maintained until the power source is cycled. The circuit interrupter is preferably autonomous, requiring no additional signals, imputs, or sources of power.
