  • Reset lockout mechanism and independent trip mechanism for center latch circuit interrupting device
    Patent number: 7098761
    Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include a reset lockout mechanism, an independent trip mechanism and reverse wiring protection. A conical reset plunger is notched to force a successful test before reset.
    Type: Grant

    Date of Patent: August 29, 2006
    Assignee: Leviton Manufacturing Co., Inc.
    Inventors: Frantz Germain, Stephen Stewart, Roger M. Bradley, David Y. Chan, Nichalas L. DiSalvo, William R. Ziegler
  • Circuit interrupting device with reset lockout and reverse wiring protection and method of manufacture
    Patent number: 7049910
    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, 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 system with independent trip and reset lockout
    Patent number: 6944001
    Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include an independent trip mechanism and a reset lockout mechanism are provided. The trip mechanism operates independently of a circuit interrupting mechanism used to break the connection, and the reset lockout mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism is non-operational or if an open neutral condition exists.
