Abstract

A power distribution assembly includes a first lug pad electrically coupled to a first phase of a run-over bus and a first cradle including a horizontal portion, a first end having a first vertical portion coupled thereto, and a second end having a second vertical portion coupled thereto. The first lug pad is received on the horizontal portion. A support is coupled to the first vertical portion and one or more braces are coupled to the second vertical portion. Lug assemblies and lug and bus assemblies are disclosed, as are other aspects.

First claim

What is claimed is:

1. A lug assembly of a power distribution system, comprising:
a first lug pad electrically coupled to a first phase of a run-over bus;
a second lug pad electrically coupled to a second phase of the run-over bus;
a first lug pad adapter electrically coupled between the first lug pad and the first phase of the run-over bus;
a second lug pad adapter electrically coupled between the second lug pad and the second phase of the run-over bus,
wherein the first lug pad adapter and the second lug pad adapter at least partially form a channel configured to receive one or more horizontally-extending conductors;
a first cradle including a horizontal portion, a first end having a first vertical portion coupled thereto, and a second end having a second vertical portion coupled thereto, the first lug pad received on the horizontal portion;
a support coupled to the first vertical portion; and
one or more braces coupled to the second vertical portion.

2. The lug assembly of claim 1 , further comprising:
a second cradle having a horizontal portion, a first end having a first vertical portion coupled to the support, and a second end having a second vertical portion coupled to the one or more braces, the second lug pad received on the horizontal portion.

3. The lug assembly of claim 2 , wherein the second cradle is in vertical alignment with the first cradle.

4. The lug assembly of claim 2 , further comprising:
a third lug pad electrically coupled to a third phase of the run-over bus; and
a third cradle having a horizontal portion, a first end having a first vertical portion coupled to the support, and a second end having a second vertical portion coupled to the one or more braces, the third lug pad received on the horizontal portion,
wherein the first lug pad, the second lug pad, and the third lug pad are in vertical alignment with each other.

5. The lug assembly of claim 1 , wherein the first lug pad adapter includes:
a first vertical portion coupled to the first phase of the run-over bus to a height greater than the height of a horizontally-extending conductor; and
a first horizontal portion coupled to the first vertical portion coupled to the first phase of the run-over bus and extending a distance greater than a width of the horizontally-extending conductor,
wherein the first vertical portion coupled to the first phase of the run-over bus and the first horizontal portion at least partially form a channel configured to receive the one or more horizontally-extending conductors.

6. The lug assembly of claim 5 , further comprising:
a second vertical portion coupled to the first horizontal portion; and
a second horizontal portion coupled between the first lug pad and the second vertical portion coupled to the first horizontal portion,
wherein the first vertical portion coupled to the first phase of the run-over bus, the first horizontal portion, and the second vertical portion coupled to the first horizontal portion at least partially form a channel configured to receive the one or more horizontally-extending conductors.

7. The lug assembly of claim 6 , wherein the second horizontal portion and the first lug pad are integrally formed.

8. The lug assembly of claim 1 , wherein the second lug pad adapter includes a vertical portion coupled to the second phase of the run-over bus and a horizontal portion coupled between the vertical portion and the second lug pad.

9. The lug assembly of claim 1 , further comprising a first lug pad adapter electrically coupled between the first lug pad and the first phase of the run-over bus, the first lug pad adapter at least partially forming a channel configured to receive a horizontally-extending conductor.

10. The lug assembly of claim 9 , wherein at least a portion of the first cradle is coupled to a support, the support including an opening configured to receive a horizontally-extending conductor.

11. A bus and lug assembly of a power distribution system, comprising:
a first lug pad;
a horizontally-extending run-over bus having one or more phases;
a first horizontally-extending conductor; and
a first lug pad adapter coupled between the first lug pad and a first phase of the horizontally-extending run-over bus, the first lug pad adapter forming a channel, wherein at least a portion of the first horizontally-extending conductor passes through the channel.

12. The bus and lug assembly of claim 11 , further comprising:
a cradle having a horizontal portion, a first end having a first vertical portion coupled thereto, and a second end having a second vertical portion coupled thereto, the first lug pad being received on the horizontal portion;
a support coupled to the first vertical portion; and
one or more braces coupled to the second vertical portion.

13. The bus and lug assembly of claim 11 , wherein the horizontally-extending run-over bus has two or more phases, each having a termination, and further comprising one or more braces coupled between each termination.

14. The bus and lug assembly of claim 11 , wherein the first lug pad adapter comprises:
a first vertical portion coupled between the first phase of the horizontally-extending run-over bus and a first end of a horizontal portion; and
a second vertical portion coupled between the first lug pad and a second end of the horizontal portion,
wherein the first vertical portion coupled between the first phase of the horizontally-extending run-over bus and the first end of the horizontal portion, the second vertical portion, and the horizontal portion at least partially form the channel.

15. The bus and lug assembly of claim 11 , further comprising:
a second lug pad located in vertical alignment with the first lug pad;
a second phase of the horizontally-extending run-over bus in horizontal alignment with the first phase of the horizontally-extending run-over bus; and
a second lug pad adapter coupled between the second lug pad and the second phase of the horizontally-extending run-over bus.

16. The bus and lug assembly of claim 15 , wherein the second lug pad adapter forms at least a portion of the channel and wherein a second horizontally-extending conductor at least partially extends through the channel.

17. The bus and lug assembly of claim 11 , further comprising:
a second lug pad located in vertical alignment with the first lug pad;
a second horizontally-extending conductor in vertical alignment with the first horizontally-extending conductor; and
a second lug pad adapter coupled between the second lug pad and a second phase of the horizontally-extending run-over bus, the second lug adapter at least partially forming the channel, and wherein at least a portion of the second horizontally-extending conductor passes through the channel.

18. The power distribution system of claim 17 , wherein the first phase and the second phase of the horizontally-extending run-over bus each have terminations, and further comprising one or more braces coupled between the terminations.

19. A power distribution assembly, comprising:
a first lug pad;
a second lug pad;
a first cradle including a horizontal portion, a first end having a first vertical portion coupled thereto, and a second end having a second vertical portion coupled thereto, the first lug pad being received on the horizontal portion;
a second cradle including a horizontal portion, a first end having a first vertical portion coupled thereto, and a second end having a second vertical portion coupled thereto, the second lug pad being received on the horizonta
