A circuit interrupter is structured to protect a protected circuit. The circuit interrupter includes a ground fault current sensor structured to sense a ground fault current in the protected circuit and a processor including a routine structured to perform a ground fault output self-test. The ground fault output self-test includes to output a trip signal within a predetermined phase angle of a zero-crossing of current flowing through the protected circuit, to stop outputting the trip signal before the zero-crossing, to determine whether the trip signal caused a pulse in the ground fault current, and to determine whether the circuit interrupter passed the ground fault output self-test based on whether the trip signal caused a pulse in the ground fault current.
A circuit interrupter structured to protect a protected circuit, the circuit interrupter comprising:
A method of performing a ground fault output self-test in a circuit interrupter structured to protect a protected circuit, the circuit interrupter including a ground fault current sensor structured to sense a ground fault current in the protected circuit, the method comprising:
A non-transitory computer readable medium storing one or more programs, including instructions, which when executed by a computer, causes the computer to perform a method of performing a ground fault output self-test in a circuit interrupter structured to protect a protected circuit, the circuit interrupter including a ground fault current sensor structured to sense a ground fault current in the protected circuit, the method comprising:
