Abstract
An arc fault circuit interrupter (AFCI) module includes a plug portion, a probe receiving portion and an AFCI test actuator for initiating a test of an AFCI protected circuit. More specifically, the plug portion includes a plurality of prongs configured to matingly engage with a standard three-prong receptacle. With this construction, upon engaging the plug portion with a AFCI protected receptacle, manipulation of the AFCI test actuator will cause a properly operating AFCI device to trip, i.e., terminate power to the AFCI protected receptacle. The module can also be provided with an AFCI circuit. The module can then be employed to protect an electrical device that is plugged into an unprotected circuit. The probe receiving portion is adapted to interconnect and expand the testing capabilities of a standard receptacle tester or, alternatively, be interconnected with various test probes associated with standard voltage testers.
