<p>An apparatus for testing an arc fault detector comprises a housing (30) having an ac power input plug (32) and an ac power output socket (34), the plug being connected to supply ac power to the socket via electrical supply conductors (L, N) inside the housing. The socket (34) allows connection of an external appliance (36) to the housing for receiving power from the plug (32) through the internal supply conductors. An arc generator (100) inside the housing is connected between the plug (32) and the socket (34). The arc generator comprises at least one pair of contacts and means to vibrate the contacts alternately open and closed.</p> |
