Abstract
A multiple pole arc-fault circuit breaker includes a first pole assembly, a second pole assembly, a microprocessor, and a single test button. At least one of the first pole assembly and the second pole assembly has a trip mechanism. The microprocessor is electrically coupled to the first pole assembly and to the second pole assembly, and, in response to receiving a single test signal, is operative to perform electrical tests for both the first pole assembly and the second pole assembly. In response to successful completion of the electrical tests, the microprocessor is further operative to actuate the trip mechanism. The single test button is mounted to the housing and includes a single test position which causes the sending of the single test signal for initiating the electrical tests.
