Patent ID: 6960916

Claim:
An apparatus for testing a circuit breaker having an overcurrent interrupt capability and a ground fault interrupt capability, the circuit breaker providing electrical power to a three conductor electrical circuit outlet wherein the three conductors are electrically active, neutral and ground, the apparatus comprising: a) a double pole normally open switch having a first pole connected to the electrically active conductor, a second pole connected to the neutral conductor, and a common pole connected to the ground conductor, and having a first position wherein the first pole is momentarily in electrical contact with the common pole, and having a second position wherein the second pole is momentarily in electrical contact with the common pole; b) a light emitting diode having an anode and cathode, said anode being electrically connected to the electrically active conductor and the first pole of said normally open switch, said cathode being electrically connected to the ground conductor and the common pole of said normally open switch; c) when said switch is operated in the first position said switch causes the electrically active conductor to be momentarily short-circuited to the ground conductor, thereby causing said overcurrent interrupt capability of said circuit breaker to cause said circuit breaker to open and said light emitting diode to cease emitting light; and d) when said switch is operated in the second position said switch causes the neutral conductor to be momentarily short-circuited to the ground conductor, thereby causing said ground fault interrupt capability of said circuit breaker to cause said circuit breaker to open and said light emitting diode to cease emitting light.
