Abstract
An electrical system includes an enclosure for housing an electrical device. The enclosure includes a door with an operating handle connected to a shaft when the door is closed, which can then be used to turn the electrical device on or off. The shaft rotation is further operable to simultaneously displace an interlock mechanism for engagement or disengagement to a busway structure.
Claims20
An electrical apparatus, comprising:
- an enclosure having a door movable for access to an interior of the enclosure;
- an electrical device disposed in the interior of the enclosure, the electrical device being operable to be turned on and off;
- an operating handle on the door outside the enclosure that is operable to open and close the door;
- a shaft engaged to the electrical device;
- and
- an interlock mechanism including an interlock device, the shaft including a first end connected to the interlock device and a second end that is engaged to the operating handle with the door closed, wherein rotation of the external operating handle with the door closed rotates the shaft to turn the electrical device on or off and further displaces the interlock device for engagement or disengagement with a busway structure.

A system for turning a shaft to operate an electrical device in an enclosure, comprising:
- an operating handle mountable on a door of the enclosure;
- a shaft engaged to the electrical device in the enclosure, wherein the shaft is engaged to the operating handle with the door closed and is disengaged from the operating handle with the door open;
- and
- an interlock mechanism including an interlock device, the shaft including a first end connected to the interlock device and a second end that is engaged to the operating handle with the door closed, wherein rotation of the handle assembly rotates the shaft to turn the electrical device on or off and further displaces the interlock device for engagement or disengagement with a busway structure
1 more element
An electrical system, comprising:
- an enclosure having a door for access to an interior of the enclosure;
- an electrical device in the interior of enclosure and a shaft extending from the electrical device;
- an operating handle disposed outside the enclosure that is coupled to a first end of the shaft through the door with the door closed and uncoupled from the first and of the shaft with the door open;
- and
- an interlock mechanism for selectively engaging the enclosure to a busway structure, the interlock mechanism being engaged to a second end of the shaft opposite the first end, wherein with the door closed rotation of the shaft via the operating handle turns the electrical device on or off and displaces the interlock mechanism to engage or disengage the busway structure.
