Patents by Inventor Nicholas L. DiSalvo

Nicholas L. DiSalvo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Circuit interrupting system with independent trip and reset lockout
    Publication number: 20020030953
    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.
    Type: Application
    Filed: August 24, 2001
    Publication date: March 14, 2002
    Inventors: William R. Ziegler, Nicholas L. DiSalvo
  • Circuit breaker with independent trip and reset lockout
    Publication number: 20020006022
    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.

  • Circuit interrupting device with reverse wiring protection
    Publication number: 20010036049
    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
    Patent number: 6288882
    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.

  • Reset lockout for circuit interrupting device
    Patent number: 6040967
    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.
