Abstract
An arc fault/ground fault circuit interrupter for a power circuit includes a line terminal; a load terminal; and separable contacts electrically connected between the line and load terminals. An operating mechanism opens the separable contacts and has a closed position for closing the separable contacts. A trip mechanism cooperates with the operating mechanism to trip open the separable contacts. A ground fault protection circuit is operatively associated with the power circuit. An arc fault protection circuit is also operatively associated with the power circuit. A circuit tests the ground fault protection circuit, tests the arc fault protection circuit, and restores the operating mechanism to the closed position responsive to sequential activation of test and reset buttons.
