Patent ID: 7098761

Claim:
A circuit interrupting device comprising: a housing; a phase conductive path disposed at least partially within said housing between a line side and a load side, said phase conducive path terminating at a first connection capable of being electrically connected to a source of electricity and a second connection capable of conduction electricity to at least one load; a circuit interrupting portion disposed within said housing and configured to cause electrical discontinuity in said phase conductive path between said line side and said load side upon the occurrence of a predetermined condition; and a reset portion disposed at least partially within said housing and configured to reestablish electrical continuity in said phase conductive path, wherein said reset portion further comprises a reset lockout portion having a spring biased reset button coupled to a shaft of a first diameter having an end section of a second diameter larger than said first diameter to form a shoulder, the end section having a conical tip and a flat section which extends from said conical tip toward said shoulder to provide a step between said tip and said shoulder, said shoulder and step being provided for separately engaging a sliding plate and a spring, and a test button coupled to a shaft to urge, when depressed, said sliding plate and spring to cause a test to determine if the circuit interrupting device is operational, if an open neutral condition exists or if a reverse wiring condition exists and, if said test is not successful, said reset lockout portion prevents reestablishing electrical continuity in said phase conductive path.
