Abstract

A busway system is provided. The busway system includes a first electrical busway section, a second electrical busway section, and a busway joint. The first and second electrical busway sections are disposed longitudinally offset from each other. The busway joint couples the first and second busway sections. The busway joint includes a plurality of busbars, a plurality of splice plates coupled to the busbars, and a vise brace surrounding the busbars and the splice plates. The splice plates and the busbars electrically couple the first and second electrical busway sections. The vise brace includes a clamp screw to selectively provide a compressive force to the busbars and the splice plates.

First claim

What is claimed is:

1. A busway system comprising:
a first electrical busway section;
a second electrical busway section, said first and said second electrical busway sections disposed longitudinally aligned with each other; and
a busway joint coupling said first and said second busway sections, said busway joint comprising:
a plurality of busbars;
a plurality of splice plates coupled to said plurality of busbars, said plurality of splice plates and said plurality of busbars configured to electrically couple said first and said second electrical busway sections; and
a vise brace surrounding said plurality of busbars and said plurality of splice plates, said vise brace comprising a clamp screw configured to selectively provide a compressive force to said plurality of busbars and said plurality of splice plates,

wherein said vise brace further comprises at least one insulative spacer configured to separate said plurality of splice plates.

2. The busway system of claim 1 , wherein said vise brace further comprises a frame including a top surface and a bottom surface, wherein the compressive force is further provided by at least one of said top surface and said bottom surface to clamp said plurality of busbars and said plurality of splice plates.

3. The busway system of claim 1 , wherein said vise brace further comprises a compression device configured to distribute the compressive force.

4. The busway system of claim 3 , wherein said compression device extends longitudinally along said plurality of busbars and said plurality of splice plates.

5. The busway system of claim 3 , wherein said compression device comprises a compression washer.

6. The busway system of claim 1 , wherein said clamp screw is configured to rotate to selectively adjust the compressive three.

7. The busway system of claim 1 , wherein said vise brace further comprises a plurality of clamp screws configured to collectively provide the compressive force to said plurality of busbars and said plurality of splice plates.

8. The busway system of claim 1 , wherein said busway joint further comprises a plurality of vise braces spaced apart at a predetermined interval along a length of said plurality of busbars and said plurality of splice plates.

9. The busway system of claim 8 , wherein said busway joint further comprises a compression plate extending through each vise brace of said plurality of vise braces, said compression plate configured to distribute the compressive forces of said vise braces along the length of said plurality of busbars and said plurality of splice plates.

10. A busway joint coupling a first busway, section and a second busway section, said busway joint comprising:
a plurality of busbars;
a plurality of splice plates coupled to said plurality of busbars, said plurality of splice plates and said plurality of busbars configured to electrically couple the first and the second busway sections; and
a vise brace externally coupled to said busbars and said splice plates, said vise brace comprising a clamp screw configured to selectively provide a compressive force to said plurality of busbars and said plurality of splice plates,
wherein said vise brace further comprises at least one insulative spacer configured to separate said plurality of splice plates.

11. The bus way joint of claim 10 , wherein said vise brace further comprises a frame including a top surface and a bottom surface, wherein the compressive force is further provided by at least one of said top surface and said bottom surface to clamp said plurality of busbars and said plurality of splice plates.

12. The busway joint of claim 10 , wherein said vise brace further comprises a compression device configured to distribute the compressive force.

13. The busway joint of claim 12 , wherein said compression device extends longitudinally along said plurality of busbars and said plurality of splice plates.

14. The busway joint of claim 12 , wherein said compression device is a compression washer.

15. The busway joint of claim 10 , wherein said clamp screw is configured to rotate to selectively adjust the compressive force.

16. The busway joint of claim 10 , wherein said vise brace, further comprises a plurality of clamp screws configured to collectively provide the compressive force to said plurality of busbars and said plurality of splice plates.
