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, if an open neutral condition exists or if the device is reverse wired. Methods for ensuring a reset lock out state before shipment are provided.

Circuit interrupting device with reset lockout and reverse wiring protection and method of manufacture

A bi-directional fault circuit interrupter system having mis-wiring protection via numerous different poles. There are at least three different transformers wherein at least two of the transformers are differential transformers and at least one transformer is a neutral transformer. There is also at least one actuator which is used to switch the switches back and forth to selectively connect the electrical current to the fault circuit.

Fault circuit interrupter with bi-directional sensing

The present invention is directed to current interrupting devices with overcurrent protection. In one embodiment, a ground fault circuit interrupter (GFCI) is disclosed having both ground fault and overcurrent protection. The GFCI has a current detection circuit that includes a switch connected across the load phase terminal and the line neutral terminal of the device. A comparator compares a predefined threshold voltage to a sensed voltage based on a current through the line and load neutral terminals of the device. If the sensed voltage exceeds the predefined threshold, the comparator causes the switch to conduct thereby tripping the device, disconnecting the load from the line terminals and preventing the overcurrent condition from causing damage to the device and/or load.

Overcurrent protection for circuit interrupting devices

The present invention relates to a family of resettable circuit interrupting devices that eliminates the need to rewire a resettable circuit interrupting device after it is installed and powered up to correct for a reverse wiring conditions.

Bi-directional ground fault circuit interrupter

A leakage current monitor device suitable for use in or with a Relocatable Power Tap. The device includes a leakage current detector circuit and an alarm circuit coupled thereto. The leakage current detector circuit is configured to detect leakage current from one or more loads connected to the RPT. The alarm circuit activates an alarm device when a detected leakage current exceeds a defined threshold.

Resettable circuit interrupting devices using a center latch are provided. The circuit interrupting devices include those with a reset lockout, reverse wiring protection, and/or an independent trip portion.

Reset lockout for sliding latch GFCI

The present disclosure relates to resettable circuit interrupting devices and apparatus capable of being tested and reset from remote locations, and in particular to portable circuit interrupting devices and apparatus capable of being tested and reset from remote locations.

Single lamp holder with ground fault circuit interrupter receptacle

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 SWand SWwill open, and line power will be disconnected from the interrupting device.

In the present invention the basic detection and interruption components of an Immersion Detection Circuit Interrupter (IDCI), in combination with the line, neutral and shield conductors of an extension or appliance cord provides a new improved type of detector, a Leakage Current Detector Interrupter (LCDI) which interrupts current to a load when current leakage is detected between the line or neutral conductors of the cord and the shield conductor. The new improved LCDI detector provides, either singularly or in combination, the following advantages: Prevents the LCDI from being reset should the device become inoperative (reset lockout); Provides an indication of the integrity of the shield in the extension or appliance cord; Tests the integrity of the shield within the extension or appliance cord, in addition to testing the functionality of the LCDI; Interrupts current to the load if an electrical connection is detected between the shield and neutral, or the shield and ground, in addition to the existing detection of leakage current from the phase conductor; Allows the LCDI to trip during an open neutral condition by utilizing the ground connection as a return wire for the trip coil; and/or Provides immersion detection at the receptacle end of the extension cord in addition to protection from leakage faults.
