Abstract: Self-test circuitry for testing a circuit interrupter includes an active element coupled to an operating mechanism, a first sub-circuit for temporarily disabling the active element, a second sub-circuit structured to generate a simulated ground fault condition, and a processing unit coupled to the ground fault detection circuitry. The first sub-circuit and the second sub-circuit, the processing unit being structured and configured to control the first sub-circuit to temporarily disable the active element and to control the second sub-circuit to generate the simulated ground fault condition when the active element is disabled. Also, self-test circuitry that includes a sub-circuit structured to generate a simulated ground fault condition and a processing unit structured and configured to control the sub-circuit to generate the simulated ground fault condition only during a predetermined portion of a half cycle of energy passing through the circuit interrupter.

Abstract: A power system is for a facility. The power system includes a load panel powered from a split phase electrical distribution configuration having a first line, a second line and a neutral. A two-pole circuit interrupter in the load panel receives power from the first line, the second line and the neutral, and protects an unbalanced load. The two-pole circuit interrupter is structured to trip open or open responsive to an input. A circuit in the load panel is structured to determine that the neutral is broken or missing and responsively output to the input to cause the two-pole circuit interrupter to trip open or open.
