Abstract
An electrical system includes an enclosure for housing an electrical device. The enclosure includes a door with an operating handle connected to a first shaft that turns the electrical device on or off when the door is closed. The operating handle is further operable to simultaneously rotate a cam assembly, which in turn rotates a second shaft which displaces 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;
- a first shaft for operating the electrical device;
- an operating handle on the door outside the enclosure that is operable to open and close the door;
- a cam assembly on the door, wherein with the door closed the operating handle is connected to electrical device with the first shaft, and the first shaft and the cam assembly are rotated by rotation of the operating handle;
- and
- an interlock mechanism including an interlock device and a second shaft, the second shaft including a first end connected to the interlock mechanism and a second end that is engaged to the cam assembly with the door closed, wherein rotation of the operating handle rotates the first shaft to turn the electrical device on or off and also rotates the cam assembly which rotates the second shaft to displace the interlock device for engagement or disengagement with a busway structure.
4 more elements
A system for turning at least two shafts to operate an electrical device in an enclosure, comprising:
- an operating handle mountable on a door of the enclosure;
- a first shaft engaged to the operating handle and to the electrical device in the enclosure with the door closed, and wherein the operating handle is disengaged from the electrical device with the door open, wherein rotation of the operating handle with the door closed turns the electrical device on or off;
- a cam assembly engaged to and rotatable by the first shaft upon rotation of the operating handle with the door closed;
- and
- an interlock mechanism including an interlock device and a second shaft, the second shaft including a first end connected to the interlock device and a second end that is engaged to the cam assembly with the door closed, wherein rotation of the cam assembly upon rotation of the first shaft rotates the second shaft to displace the interlock device for engagement or disengagement with a busway structure
2 more elements
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 first shaft extending therefrom;
- an operating handle disposed outside the enclosure and coupled to the electrical device with the first shaft through the door with the door closed, wherein the operating handle is operative to rotate the first shaft to turn the electrical device on or off;
- an interlock mechanism for selectively engaging the enclosure to a busway structure;
- and
- a cam assembly on the door that is connected to the interlock mechanism via a second shaft, wherein the cam assembly is operable upon rotation of the first shaft via the operating handle to rotate the second shaft and displace the interlock mechanism to engage or disengage the busway structure.
