Abstract
A combined ground fault and arc fault detector includes interrupting contacts which are opened when either an arc fault or a ground fault is detected. The detector includes a test circuit which creates a simulated fault and momentarily de-energizes the coil to test the detector and re-energizes the coil before the interrupting contacts open.
