Abstract
A self-testing arc fault or ground fault detector includes arc fault detecting circuitry and components. The detector includes a testing circuit which tests at least part of the circuitry and components and generates a recurring signal when the test completes successfully. If the test does not complete successfully, the signal is lost. This loss of signal is signaled by an indicator connected to the testing circuit. In one version, the loss of signal activates a circuit interrupter which disconnects the load side of the detector from the line side.
