  • Circuit interrupting device with reverse wiring protection
    Publication number: 20040196600
    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.

  • Circuit breaker with independent trip and reset lockout
    Publication number: 20040184207
    Abstract: Resettable circuit breakers having an independent trip mechanism and a reset lockout are provided. The trip mechanism operates independently of the fault protection operations, and the reset lockout prevents the resetting of the circuit breaker if the fault protection is non-operational or if an open neutral condition exists.

  • Pivot point reset lockout mechanism for a ground for fault circuit interrupter
    Patent number: 6771152
    Abstract: Resettable circuit interrupting devices, such as GFCI devices that include a reset lockout mechanism, are provided. The reset lockout comprises a member coupled to swing from a pivot which moves with a reset button to permit the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism used to break the connection is non-operational or if an open condition exists.

  • Self heating thermal protector
    Publication number: 20040136194
    Abstract: The present invention is a self heating thermal protector located in close proximity to an incandescent light fixture for controlling the flow of current to the associated lighting fixture by measuring the rate of heat flow from a dedicated heat source. Current is permitted to flow to the lighting fixture when the temperature of the self heating thermal detector is sufficient to avoid deterioration of electrical components such as plastic parts and wire insulation in the associated fixture. The thermal detector interrupts the flow of current to the associated fixture when the temperature of the self heating thermal protector increases to a temperature that is not safe.

  • Reset lockout for circuit interrupting device
    Publication number: 20040108923
    Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include a reset lock-out mechanism are provided. The reset lock-out mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism used to break the connection is non-operational or if an open neutral condition exists.
