  • Remote operated ground fault circuit breaker
    Patent number: 10950403
    Abstract: A circuit interrupter electrically connects a line terminal to a load terminal in a closed condition and electrically disconnects the line terminal from the load terminal in the open condition. A controller includes a fault detector configured to detect a fault in an electrical signal in a load circuit, such that when a fault is detected on the load circuit, the fault detector causes actuation of the interrupter to the open condition. The controller is adapted to receive an off command, and in response to the off command, generate a simulated fault in the load circuit, such that the fault detector causes actuation of the interrupter to the open condition, such that one and the same interrupter is employed for both fault tripping and commanded tripping.
