Abstract

An electrical enclosure system includes a housing includes an interior cavity for receiving electrical components. The electrical enclosure system includes at least one dual bus bar arranged in the interior cavity. The at least one dual bus bar includes a first bus bar, and a second bus bar arranged alongside and connected to the first bus bar through an insulated connection. The first bus bar is configured to carry a first electrical current and the second bus bar is configured to carry a second electrical current that is distinct from the first electrical current. An electrical component is arranged in the housing. The electrical component includes a dual bus bar connector operatively connected to and electrically connected to the dual bus bar. The dual bus bar connector includes a first connector portion and a second connector portion electrically isolated from the first connector portion.

First claim

What is claimed is:

1. An electrical enclosure system including a housing having at least a rear wall and a plurality of side walls extending from the rear wall to form an interior cavity configured to receive electrical components, the electrical enclosure system comprising:
at least one dual bus bar including a first bus bar, and a second bus bar arranged alongside and connected to the first bus bar through an insulated connection, the first bus bar being configured to carry a first electrical current and the second bus bar being configured to carry a second electrical current that is distinct from the first electrical current; and
an electrical compartment arranged in the housing, and selectively shiftable between a first connected position and a second disconnected position, the electrical compartment including a dual bus bar connector electrically connected to the dual bus bar when in the first connected position, the dual bus bar connector including a first connector portion and a second connector portion operatively connected to and electrically isolated from the first connector portion, the first and second connector portions exerting a clamping force on the dual bus bar when in the first connected position;
wherein the dual buabar is arranged within the interior cavity and disposed external to the electrical compartment.

2. The electrical enclosure system according to claim 1 , wherein the first connector portion forms a first stab connector portion and the second connector portion forms a second stab connector portion, the first and second stab connector portions forming a single stab connector electrically connected to the at least one dual bus bar.

3. The electrical enclosure system according to claim 2 , wherein the first and second connector portions further comprise respective end portions including respective terminals arranged to provide a connection point for respective electrical conductors.

4. The electrical enclosure system according to claim 3 , wherein the respective end portions of the first and second connector portions are disposed within the interior cavity, and the respective stab portions of the first and second connector portions are disposed to protrude therefrom.

5. The electrical enclosure system according to claim 3 , wherein the the dual bus bar connector further comprises a mounting member coupled to the electrical compartment.

6. The electrical enclosure system according to claim 1 , wherein the insulated connection includes an insulated coating disposed on the surface of at least one of the first and second bus bars.

7. The electrical enclosure system according to claim 6 , wherein the insulated coating includes a void region at a predetermined axial position on the first and second bus bars, the void region exposing a portion of the at least one first and second bus bars.

8. The electrical enclosure system according to claim 7 , wherein each of the first and second bus bars includes a side portion and an edge portion, the void region extends from the side portion to the edge portion.

9. The electrical enclosure system according to claim 1 , wherein the insulated connection is an insulator joining the first bus bar directly to the second bus bar.

10. The electrical enclosure system according to claim 6 , wherein the insulated connection includes a first insulated coating disposed on the first bus bar and a second insulated coating disposed the second bus bar.

11. The electrical enclosure system according to claim 10 , wherein the first insulated, covering includes a first void region at a predetermined axial position on the first bus bar and the second insulated covering includes a second void region on the second bus bar, the first void region exposing a portion of the first bus bar and the second void region exposing a portion of the second bus bar.

12. The electrical enclosure system according to claim 11 , wherein the first void region is axially aligned with the second void region.
