Abstract

An electrical enclosure includes gap-free trim plate installation. A switchboard or power panel includes an enclosure face with a central opening covered by a top label plate, a bottom label plate and a plurality of trim plates. The trim plate flanges cooperatively engage one another in an interlocking fashion. The interlocking arrangement allows the trim plates to remain in their installed position without external restraint during installation and removal.

Claims

1. A trim plate providing a gap-free installation with at least one adjacent trim plate in a switchboard, power panel or telecommunications enclosure, comprising:

a substantially planar center panel;

a trim plate first flange having a first flange shape configured to cooperatively engage a second flange of a first adjacent trim plate; and

a trim plate second flange having a second flange shape configured to cooperatively engage a first flange of a second adjacent trim plate,

wherein at least one of said trim plate first flange and said trim plate second flange extends a length defining a length of said center panel, one end of said trim plate is free to pivot about an opposite end of said trim plate for removal and installation of said trim plate disposed between said first and second adjacent trim plates.

2. The trim plate as described in claim 1, wherein the cooperative engagement provides an overlap between adjacent trim plates eliminating a potential gap between said adjacent trim plates.

3. The trim plate as described in claim 2, wherein said trim plate first flange shape and trim plate second flange shape interlock said trim plate with said first adjacent trim plate and said second adjacent trim plate.

4. The trim plate as claimed in claim 3, wherein said trim plate first flange shape and said trim plate second flange shape are configured to allow said trim plate to be hingedly coupled with said first and second adjacent trim plates.

5. The trim plate as claimed in claim 4, wherein interlock of said trim plate with said first adjacent trim plate and said second adjacent trim plate allow said trim plate to remain in an installation position without the use of fasteners or external restraints.

6. The trim plate as claimed in claim 5, wherein said first flange shape and said second flange shape are dissimilar.

7. The trim plate as claimed in claim 6, wherein said first flange is formed as a ninety degree bend along a first edge of said trim plate.

8. The trim plate as claimed in claim 7, wherein said second flange is formed as a U-shape along a second edge of said trim plate.

9. The trim plate as claimed in claim 8, wherein said ninety degree bend faces outward.

10. The trim plate as claimed in claim 9, wherein said U-shape faces inward.

11. The trim plate as claimed in claim 10, wherein said planar center panel extends a width of said trim plate between a trim plate first end and a trim plate second end.

12. The trim panel as claimed in claim 11, wherein said trim plate is a filler plate.

13. The trim plate as claimed in claim 11, wherein said planar panel includes at least one cutout.

14. The trim plate as claimed in claim 13, wherein said trim plate is a breaker cover.

15. An enclosure for electrical or telecommunications equipment providing a gap-free trim plate installation, comprising:

an enclosure body; and

a plurality of trim plates, wherein each trim plate of said plurality of trim plates includes;

a substantially planar center panel,

a trim plate first flange having a first flange shape configured to cooperatively engage a second flange of a first adjacent trim plate, and

a trim plate second flange having a second flange shape configured to cooperatively engage a first flange of a second adjacent trim plate, at least one of said trim plate first flange and said trim plate second flange extends a length defining a length of said center panel, one end of said trim plate is free to pivot about an opposite end of said trim plate for removal and installation of said trim plate disposed between said first and second adjacent trim plates.

16. The enclosure as described in claim 15, wherein said first flange shape and second flange shape interlock said trim plates with one another when installed in said enclosure.

17. The enclosure as claimed in claim 16, wherein said first flange shape and said second flange shape arc configured to allow said trim plates to be hingedly coupled with one another.

18. The enclosure as claimed in claim 17, wherein a cooperative engagement of said first flange and said second flange allows said trim plates to remain in an installation position without the use of fasteners or other external restraint.

19. The enclosure as claimed in claim 18, wherein said first flange shape and said second flange shape are dissimilar.

20. The enclosure as claimed in claim 19, wherein said first flange is formed as a ninety degree bend along a first edge of said trim plates.

21. The enclosure as claimed in claim 20, wherein said second flange is formed as a U-shape along a second edge of said trim plates.

22. The enclosure as claimed in claim 21, wherein said ninety degree bend faces outward.

23. The enclosure as claimed in claim 22, wherein said U-shape faces inward.

24. The enclosure as claimed in claim 23, wherein said trim plates can be removed as a single piece.

25. The enclosure as claimed in claim 24, wherein said trim plates are attached to a cover collector.

26. The enclosure as claimed in claim 25, wherein said electrical enclosure is an electrical panelboard.

27. The electrical panelboard as claimed in claim 26, wherein said electrical panelboard is a switchboard.

28. The electrical panelboard as claimed in claim 27, wherein said electrical panelboard is a power panel.

29. A method of gap-free trim plate installation, the steps comprising:

providing an electrical panelboard front;

providing a plurality of trim plates, each trim plate with an interlocking flange at one end and an opposite end, at least one of said interlocking flange at said one end and a said opposite end extending a length of said trim plate;

configuring said one end of said trim plate to freely pivot about said opposite end of said trim plate for removal and installation of said trim plate disposed between a first adjacent trim plate and a second adjacent trim plate;

securing a first trim plate to said panelboard front;

interlocking a first flange of a second trim plate with a second flange of said first trim plate;

releasing said second trim plate; and

installing trim plate mounting fasteners.

30. The method of claim 29, wherein said first flange is formed as a ninety degree bend along a first edge of said trim plates.

31. The method of claim 30, wherein said second flange is formed as a U-shape along a second edge of said trim plates.

32. The method of claim 31, wherein said ninety degree bend faces outward.

33. The method of claim 32, wherein said U-shape faces inward.
