Abstract
A handle assembly and related methods for actuating a mechanism such as a disconnect switch.
Claims13
An apparatus for providing access to a control enclosure, the apparatus comprising:
- a handle assembly including a handle and a rotator;
- a base assembly including a base, the handle is rotatably coupled with the base, the base having a housing with an opening therein;
- a shaft extending from a first end portion to a second end portion, wherein:
- the first end portion is adapted to engage with a disconnect switch or circuit breaker, and
- the second end portion is engaged with the rotator of the handle assembly;
- and
- a defeater configured to selectively engage a catch on the second end portion of the shaft to prevent longitudinal movement of the shaft relative to the handle assembly, wherein:
- the defeater engages the catch in a first position,
- the defeater disengages the catch in a second position, and
- wherein the base assembly is configured such that an elongate member can be disposed though the opening in the housing of the base assembly such that the defeater is accessible via the opening in the housing of the base assembly to move the defeater between the first position and the second position.

- a handle assembly including a handle and a rotator;
- a base assembly including a base, the handle is rotatably coupled with the base;
- a defeater disposed within the base assembly;
- the base having a housing with an opening therein, the opening providing access to the defeater;
- and
- a shaft extending from a first end portion to a second end portion, wherein:
- the first end portion is adapted to engage with a disconnect switch or circuit breaker,
- the second end portion is engaged with the rotator of the handle assembly, and
- wherein the defeater is configured to selectively engage a catch on the second end portion of the shaft to prevent longitudinal movement of the shaft relative to the handle assembly, and an arrangement of the base assembly, the second end portion, and the defeater is configured such that the defeater can be overridden by movement of the defeater between a first position and a second position so as to disengage the defeater from the catch.

An apparatus for providing access to a control enclosure, the apparatus comprising:
- a handle assembly including a handle and a rotator, wherein the handle assembly is rotated in a direction to open an enclosure dooaxr when the handle assembly is mounted to the enclosure door;
- a base assembly including a base, the handle is rotatably coupled with the base;
- a defeater disposed within the base assembly, where the defeater can be overridden by the defeater being movable along an axis, the axis is other than in the direction the handle assembly is moved to open the enclosure door;
- the base having a housing with an opening therein, the opening being configured such that an elongate member can be disposed though the opening, thereby providing access to the defeater;
- and
- a shaft extending from a first end portion to a second end portion, wherein:
- the first end portion is adapted to engage with a disconnect switch or circuit breaker,
- the second end portion is engaged with the rotator of the handle assembly, and
- wherein the second end portion includes a catch configured to be selectively engaged by the defeater to prevent longitudinal movement of the shaft relative to the handle assembly, and an arrangement of the base assembly, the second end portion, and the defeater is configured such that the defeater can be overridden by movement of the defeater between a first position and a second position along the axis so as to disengage the defeater from the catch.
