Abstract

A ground bus subassembly provided at a top (e.g., top front) of a power distribution cabinet section. The ground bus subassembly includes a first upper front frame plate, and a first ground bus section adjacent to the first upper front frame plate. A splice can attach to the first ground bus section. A ground cover covering the first ground bus section can function as a hoist rail. Ground bus subassemblies with first and second cabinet sections and first and second ground bus sections are provided, as are methods of assembly of ground bus subassemblies.

First claim

What is claimed is:

1. A ground bus subassembly, comprising:
a first upper front frame plate;
a first ground bus section coupled to the first upper front frame plate; and
a first ground cover covering the first ground bus section, wherein the first ground cover comprises a hoist rail that is configured to support a hoist thereon,
wherein the ground bus subassembly provides a location for a ground bus inside the hoist rail such that the ground bus can be easily accessed from a top front of a cabinet section, and
wherein attachment to the first upper front frame plate at shipping splits is easily accessible without compromising the hoist rail functionality.

2. The ground bus subassembly of claim 1 , wherein the first ground cover operatively covers an entire length of the first ground bus section.

3. The ground bus subassembly of claim 1 , comprising a splice coupled to one end of the first ground bus section.

4. The ground bus subassembly of claim 3 , wherein the splice is coupled to the first ground bus section by fasteners passing through the splice and the first ground bus section and secured to the first upper front frame plate or a corner bracket.

5. The ground bus subassembly of claim 1 , comprising a splice coupled to two ends of the first ground bus section.

6. The ground bus subassembly of claim 1 , comprising a splice coupled to a first end of the first ground bus section and a second end the first ground bus section directly coupled to the first upper front frame plate by fasteners.

7. The ground bus subassembly of claim 1 , comprising a ground cover covering the first ground bus section and an end plate covering an end of the ground cover.

8. The ground bus subassembly of claim 1 , comprising a second upper front frame plate adjacent to the first upper front frame plate.

9. The ground bus subassembly of claim 8 , comprising a second ground bus section coupled to the second upper front frame plate wherein the coupling is provided by a splice.

10. The ground bus subassembly of claim 9 , comprising first fasteners passing through the splice and the first ground bus section and secured to the first upper front frame plate or to a first corner bracket, and second fasteners passing through the splice and the second ground bus section and secured to the second upper front frame plate or to a second corner bracket.

11. The ground bus subassembly of claim 9 , comprising a first ground cover covering the first ground bus section and a second ground cover covering the second ground bus section.

12. The ground bus subassembly of claim 1 , comprising a terminal opening formed in the first upper front frame plate, the terminal opening configured to allow connection of a ground terminal to a connection feature of the first ground bus section.

13. The ground bus subassembly of claim 12 , wherein the connection feature is provided between a first end and a second end of the first ground bus.

14. The ground bus subassembly of claim 12 , comprising a ground terminal attached to a connection feature of the first ground bus section.
