Abstract

The present invention is directed to an electrical equipment enclosure assembly, particularly those used to house power distribution equipment. The enclosure uses the internal structural members and panel components to form the enclosure frame. The present invention is also designed to be mounted in the 2 ft.×2 ft. (600 mm×600 mm) tile space provided in raised flooring. The enclosure is also provided with a junction box that is mounted beneath the raised flooring to allow users to terminate wiring.

Claims

1. A remote distribution cabinet comprising:

at least one internal panel;

at least one panelboard attached to the internal panel, said panelboard having a plurality of circuit breakers thereon;

a plurality of structural members forming a portion of an exterior surface of said cabinet, said structural members being attached to the internal panel thereby forming a frame structure including the structural members, the internal panel and the panelboard; and

a bottom member attached to the structural members.

2. The remote distribution cabinet of claim 1 wherein the bottom member is sized to allow the remote distribution cabinet to fit within a raised floor tile space.

3. The remote distribution cabinet of claim 2 further comprising a junction box attached to the bottom member so as to be disposed beneath a raised floor.

4. The remote distribution cabinet of claim 1 further comprising at least one access panel covering the plurality of circuit breakers.

5. The remote distribution cabinet of claim 4 wherein the access panel allows visual inspection of the circuit breakers without opening the access panel.

6. The remote distribution cabinet of claim 4 wherein said access panel is adjustable to allow for a shift in the position of the circuit breakers within the panelboard.

7. The remote distribution cabinet of claim 1 comprising at least two panelboards wherein one or more panelboards are arranged to receive power from different sources.

8. The remote distribution cabinet of claim 7 further comprising a tie-breaker for providing power from one of a plurality of sources to one or more panelboards.

9. The remote distribution cabinet of claim 1 further comprising a tie-breaker for providing power from one of a plurality of sources to one or more panelboards.

10. The remote distribution cabinet of claim 1 further comprising a current monitoring unit arranged to measure the current of each panelboard.

11. The remote distribution cabinet of claim 1 further comprising at least one main circuit breaker for each panelboard.

12. The remote distribution cabinet of claim 1 further comprising an access panel separately covering each of the at least one panelboards, wherein when the access panel is removed, service can be performed on the at least one panelboard without exposing other energized components of the remote distribution cabinet.

13. The remote distribution cabinet of claim 12 wherein the access panel allows visual inspection and operation of the panelboard circuit breakers without opening the access panel.

14. The remote distribution cabinet comprising:

at least one internal panel having at least one panelboard affixed thereto;

a frame structure comprising a plurality of structural members, each of said structural members forming a portion of an exterior surface of said cabinet; and

means for incorporating said panelboard and internal panel into said frame structure.

15. The remote distribution cabinet of claim 14 wherein the means for incorporating said panelboard into the frame structure includes a bottom member sized to allow the remote distribution cabinet to fit within a raised floor tile space.

16. The remote distribution cabinet of claim 15 further comprising a junction box attached to the bottom member so as to be disposed beneath a raised floor.

17. The remote distribution cabinet of claim 14 wherein the panelboard comprises a plurality of circuit breakers and the remote distribution cabinet further comprises at least one access panel covering the plurality of circuit breakers.

18. The remote distribution cabinet of claim 17 wherein the access panel allows visual inspection of the circuit breakers without opening the access panel.

19. The remote distribution cabinet of claim 17 wherein said access panel is adjustable to allow for a shift in the position of the circuit breakers within the panelboard.

20. The remote distribution cabinet of claim 14 comprising at least two panelboards wherein one or more panelboards are arranged to receive power from different sources.

21. The remote distribution cabinet of claim 20 further comprising a tie-breaker for providing power from one of a plurality of sources to one or more panelboards.
