Abstract

The present invention provides a fuse holder for supporting a plurality of fuses for electrical distribution equipment such as a distribution transformer. The fuse holder comprises a first end plate attached to a first distal end of the fuses; and a second end plate attached to a second distal end of the fuses. The first and second end plates have a plurality of relief cuts to permit an increased surface creep distance and are constructed of an electrically non-conductive material. A top plate, having wire routing openings for retaining wire bundles of the electrical distribution equipment, is attached to the top of the first and second end plates.

Claims

1. A fuse holder for supporting a plurality of fuses for electrical distribution equipment, said fuse holder comprising:

a first end plate attached to a first distal end of said fuses;

a second end plate attached to a second distal end of said fuses, wherein said first and said second distal ends of said fuses penetrating said first and said second end plates respectively; and

said each first and second end plates having a relief cut substantially separating said distal ends of said fuses attached to said first and second end plates.

2. The fuse holder of claim 1 further comprising a top plate attached to said first and second end plates.

3. The fuse holder of claim 1, wherein said top plate includes a wire routing opening to retain a plurality of wires of said electrical distribution equipment.

4. The fuse holder of claim 1, wherein said relief cut is I-shaped.

5. The fuse holder of claim 1, wherein said end plates comprise electrically non-conductive material.

6. The fuser holder of claim 1 wherein said distribution equipment further comprises a distribution transformer.

7. The fuse holder of claim 6, wherein said first and second end plates are attached to a top clamp of an interior clamping assembly of said distribution transformer.

8. The fuse holder of claim 1, wherein said plurality of fuses further comprises a plurality of a current protection fuses, current limiting fuses or energy limiting fuses.

9. The fuse holder of claim 3, wherein said wire routing opening is located along a cantilevered edge of said top plate, said wire routing opening further comprising a plurality of openings.

10. The fuse holder of claim 2, wherein said top plate comprises an electrically non-conductive material.
