Abstract

A system for evaluating at least one tripping stimulus for a ground-fault circuit interrupter includes: a sensing circuit configured to measure a leakage current from a voltage line to ground, wherein the sensing circuit is capable of generating a leakage signal including a voltage representative of the leakage current; and an evaluating circuit configured to evaluate the leakage signal to generate an indication signal, wherein the indication signal includes information corresponding to the at least one tripping stimulus. The sensing circuit may include a circuit substantially similar to at least a portion of a ground-fault circuit interrupter, and the evaluating circuit may include a peak hold circuit. The system may further include an indicator circuit for receiving the indication signal and displaying a status of the tripping conditions.
