Abstract
A resettable circuit interrupting device having a single button for activating a test/reset mechanism. The circuit interrupting device can include a reset lockout and/or reverse wiring protection.
Claims20
A circuit interrupting device comprising:
- a phase conductive path and a neutral conductive path each having a line side and a load side;
- a circuit interrupter configured to cause the circuit interrupting device to change from a reset state to a trip state upon the occurrence of a predetermined condition;
- a reset assembly configured to perform a reset operation when activated;
- and
- a single action test/reset assembly having a first shaft and a second shaft, and at least two springs with a first spring being coupled to said first shaft to form a spring loaded shaft, and a second spring being coupled to said second shaft to form a spring loaded shaft, said assembly which when activated is configured to perform a test operation when the circuit interrupting device is in the reset state which results in said circuit interrupter changing from a reset state to a trip state, and configured to perform a reset operation when the circuit interrupting device is in the trip state.
2 more elements
A circuit interrupting device comprising:
- a housing;
- a phase conductive path and a neutral conductive path each disposed at least partially within the housing between a line side and a load side, the phase conductive path terminating at a first connection capable of being electrically connected to a source of electricity, a second connection capable of conducting electricity to at least one load and a third connection capable of conducting electricity to at least one user accessible load, and the neutral conductive path terminating at a first connection capable of being electrically connected to a source of electricity,
- a second connection capable of providing a neutral connection to the at least one load and
- a third connection capable of providing a neutral connection to the at least one user accessible load;
- a circuit interrupting assembly disposed within the housing and configured to cause the circuit interrupting device to change from a reset state to a trip state upon the occurrence of a predetermined condition;
- a reset assembly disposed within the housing and configured to perform a reset operation when activated;
- and
- a single action test/reset assembly having a first shaft and a second shaft, and at least two springs with a first spring being coupled to said first shaft to form a spring loaded shaft, and a second spring being coupled to said second shaft to form a spring loaded shaft, said assembly being disposed at least partially within the housing and which when activated is configured to perform a test operation when the circuit interrupting device is in the reset state which results in said circuit interrupter changing from a reset state to a trip state, and configured to perform a reset operation when the circuit interrupting device is in the trip state.
