Abstract
A miniature circuit breaker incorporating ground fault protection and arc fault protection includes a test mechanism including a ground fault test circuit for testing a ground fault detector trip mechanism, and an arc fault test circuit for testing an arc fault detector trip mechanism. A state machine circuit automatically controls the test mechanism to sequentially test both of the ground fault and arc fault detector trip mechanisms. A test push button is interconnected with the state machine circuit and, when pressed, initiates sequential testing of both of the ground fault and arc fault trip mechanisms.
