Embodiment Construction

[0036] The present invention contemplates different types of disconnecting devices that can detect ground faults and reverse wiring. At least one conducting path is arranged in the device according to the invention. The conduction path is typically split between a line side connected to a power source and a load side connected to one or more loads. As mentioned above, different devices in the same family of resettable circuit breakers include: Ground Fault Circuit Interrupter (GFCI), Arc Fault Circuit Interrupter (AFCI); Immersion Detection Circuit Interrupter (IDCI); Equipment Leakage Circuit Interrupter (ALCI); circuit breaker (ELCI).

[0037] For the purposes of this application, the structure or mechanism for the circuit breaker shown in the drawings and described hereinafter is incorporated in a GFCI device suitable for installation in, for example, a single group used in a residential wiring system. inside the junction box. However, the mechanism of the present applic...

Abstract

A resettable circuit interrupting device having a switch and timer circuit connected to the line side of the interrupting device to cause a leakage current to flow for a defined interval of time when power is applied. The timer and switch circuit comprises a timer powered by current from the phase leg of the device which is designed to operate for a defined interval of time. The timer starts operating when power is applied to the circuit interrupting device and normally continues to operate for the defined interval to time. Upon completion of the timed interval, the timer turns itself off and stays off until power is again applied to the device after an interruption. When power is first applied to the interrupting device, the timer is energized from the phase leg and causes the switch to close which connects the neutral leg on the line side of the interrupting device to a ground terminal. If the device is not reverse wired, the timer continues to operate and the switch remains closed until the timer completes its cycle, at which time the switch opens and the neutral leg of the device is no longer connected to the ground terminal. If the device is reverse wired, then at some instant after the switch is closed the device will sense a reverse wired fault, the switches SW1 and SW2 will open, and line power will be disconnected from the interrupting device.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. 119(e) to U.S. Provisional Patent Application Serial No. 60 / 444,577, filed February 3, 2003. technical field [0003] This application relates to a family of resettable circuit breakers and systems, including: Ground Fault Circuit Interrupters (GFCI); Arc Fault Circuit Interrupters (AFCI); Immersion Detection Circuit Interrupters (IDCI); Equipment Leakage Circuit Interrupters (ALCI); ELCI); breakers; contactors; latching relays and solenoid mechanisms. More specifically, the present application relates to a circuit breaking device that includes a circuit breaking portion that interrupts a conductive path at both the line side and the load side of the circuit breaking device. Background technique [0004] Many wiring devices have a line side connected to a power source, a load side connectable to one or more loads, and at least one conductive path arranged between the li...
