Circuit interrupting device with reverse wiring protection
DCFirst Claim
1. A circuit interrupting device comprising:
- a first electrical conductor capable of being electrically connected to a source of electricity;
a second electrical conductor capable of conducting electrical current to a load when electrically connected to said first electrical conductor;
a third electrical conductor capable of being electrically connected to user accessible plugs and/or receptacles where the first, second and third electrical conductors are electrically isolated from each other;
at least one movable bridge electrically connected to the first electrical conductor, said at least one movable bridge capable of electrically connecting the first, second and third electrical conductors to each other;
a circuit interrupting portion configured to cause electrical discontinuity between said first, second and third electrical conductors upon the occurrence of a predetermined condition; and
a reset portion configured to reestablish electrical continuity between the first, second and third electrical conductors after said predetermined condition occurs.

Abstract
Resettable circuit interrupting devices, such as GFCI devices, that include reverse wiring protection, and optionally an independent trip portions and/or a reset lockout portion are provided. The reverse wiring protection operates at both the line and load sides of the device so that in the event line side wiring to the device is improperly connected to the load side, fault protection for the device remains. The trip portion operates independently of a circuit interrupting portion used to break the electrical continuity in one or more conductive paths in the device. The reset lockout portion prevents the reestablishing of electrical continuity in open conductive paths if the circuit interrupting portion is non-operational or if an open neutral condition exists.
