    Abstract: A system includes a circuit interrupter including a light source structured to output light and a first processor structured to obtain information associated with the circuit interrupter and to control the light source to output light in a pattern representing the information. The system also include an adapter structured to detect light output by the light source, convert the detected light to another form, and to output the converted form of the light and an electronic device structured to receive the converted form of the light. The electronic device includes a second processor structured to convert the converted form of the light into the information.

    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 circuit interrupter including a first set of separable contacts, a second set of separable contacts, a first operating mechanism structured to open the first set of separable contacts, a second operating mechanism structured to open and close the second set of separable contacts, and an electronic trip unit including a routine structured to detect a fault condition and a type of the fault condition, to control the second operating mechanism to open the second set of separable contacts in response to detecting a first type of fault condition, and to control the second operating mechanism to close the second set of separable contacts a predetermined amount of time after controlling the second operating mechanism to open the second set of separable contacts.
