Abstract
An electrical system includes an enclosure for housing an electrical device that is capable of being turned on and off. The enclosure includes a door with an operating handle that, when the door is closed, can be used to turn the electrical device on or off. The operating handle is further operable to displace an interlock mechanism for engagement or disengagement to a busway structure and indicate a status of the electrical device as on, off, or tripped.
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 or off;
- an operating handle on the door outside the enclosure that is operable to open and close the door, wherein with the door closed the operating handle is engaged to the electrical device and with the door open the operating handle is disengaged from the electrical device;
- a cam assembly on the door that rotates with rotation of the operating handle;
- and
- an interlock mechanism including an interlock device, wherein the interlock mechanism is connected to the cam assembly, wherein with the door closed rotation of the operating handle turns the electrical device on or off and rotates the cam assembly which displaces the interlock device for engagement or disengagement with a busway structure.

A system to operate an electrical device in an enclosure, comprising:
- an operating handle mountable on a door of the enclosure;
- a shaft for engaging the operating handle to the electrical device in the enclosure with the door closed and for disengaging the operating handle 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 shaft via the operating handle;
- and
- an interlock mechanism including an interlock device, the interlock mechanism being removably engaged to the cam assembly with the door closed for rotation via the cam assembly upon rotation of the operating handle 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 shaft extending therefrom, wherein the electrical device is configured to be operated by a rotation of the shaft;
- an operating handle disposed outside the enclosure and coupled to the electrical device with the door closed, wherein the operating handle is operative to rotate the 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, wherein the cam assembly is operable upon rotation of the operating handle to displace the interlock mechanism to engage or disengage the busway structure.
