Abstract

An improved electrical system may be provided by electrically isolating horizontal power distribution bus bars of differing phases, disposed along a preconfigured isolated bus support molding, from one another by covering each bus bar with an electrically insulating molded assembly. The electrically insulating molded assembly has contours configured to cover a particular bus bar (with respect to another bus bar or live fastener), arranged within the constraints of the preconfigured isolated bus support molding in the electrical system (such as along the back of the isolated bus support, between the isolated bus support and a wall of the electrical system).

Claims

1. A system for isolating power conductors comprising:

a bus support;

first and second power conductors disposed proximal to one another along the bus support, wherein the bus support directly supports the first and second power conductors; and

an electrically insulating molded assembly having at least one contour configured to cover at least one of the first and second power conductors,

wherein the at least one of the first and second power conductors that is covered by the electrically insulating molded assembly is electrically insulated by the bus support on one side and by the electrically insulating molded assembly on an opposing side,

wherein the electrically insulating molded assembly includes an opening in the at least one contour configured to allow passage to the at least one of the first and second power conductors, and

wherein the opening is located in at least one of a left side and a right side of the electrically insulating molded assembly.

2. The system of claim 1, wherein the contour provides a substantially flat area disposed directly over the at least one of the first and second power conductors.

3. The system of claim 2, wherein the contour is followed by a curved area disposed over an edge of the at least one of the first and second power conductors.

4. The system of claim 1, further comprising an electrically insulating molded boot attached to the electrically insulating molded assembly over the opening.

5. The system of claim 1, wherein the electrically insulating molded assembly is a single injection molded part.

6. The system of claim 1, wherein the electrically insulating molded assembly is a first electrically insulating molded assembly configured to cover the first power conductor, and further comprising a second electrically insulating molded assembly configured to cover the second power conductor, wherein the first and second electrically insulating molded assemblies are in contact with one another.

7. A system for isolating power conductors comprising:

a bus support;

first and second power conductors disposed proximal to one another along the bus support, wherein the bus support directly supports the first and second power conductors; and

an electrically insulating molded assembly having at least one contour configured to cover at least one of the first and second power conductors,

wherein the at least one of the first and second power conductors that is covered by the electrically insulating molded assembly is electrically insulated by the bus support on one side and by the electrically insulating molded assembly on an opposing side,

wherein the electrically insulating molded assembly includes an opening in the at least one contour configured to allow passage to the at least one of the first and second power conductors, and

further comprising an electrically insulating molded boot attached to the electrically insulating molded assembly over the opening.

8. The system of claim 7, wherein the contour provides a substantially flat area disposed directly over the at least one of the first and second power conductors.

9. The system of claim 8, wherein the contour is followed by a curved area disposed over an edge of the at least one of the first and second power conductors.

10. The system of claim 7, wherein the opening is located in at least one of a left side and a right side of the electrically insulating molded assembly.

11. The system of claim 7, wherein the electrically insulating molded assembly is a single injection molded part.

12. The system of claim 7, wherein the electrically insulating molded assembly is a first electrically insulating molded assembly configured to cover the first power conductor, and further comprising a second electrically insulating molded assembly configured to cover the second power conductor, wherein the first and second electrically insulating molded assemblies are in contact with one another.

13. A system for isolating power conductors comprising:

a bus support;

first and second power conductors disposed proximal to one another along the bus support, wherein the bus support directly supports the first and second power conductors; and

an electrically insulating molded assembly having at least one contour configured to cover at least one of the first and second power conductors,

wherein the at least one of the first and second power conductors that is covered by the electrically insulating molded assembly is electrically insulated by the bus support on one side and by the electrically insulating molded assembly on an opposing side,

wherein the electrically insulating molded assembly is a first electrically insulating molded assembly configured to cover the first power conductor, and further comprising a second electrically insulating molded assembly configured to cover the second power conductor, wherein the first and second electrically insulating molded assemblies are in contact with one another.

14. The system of claim 13, wherein the contour provides a substantially flat area disposed directly over the at least one of the first and second power conductors.

15. The system of claim 14, wherein the contour is followed by a curved area disposed over an edge of the at least one of the first and second power conductors.

16. The system of claim 13, wherein the electrically insulating molded assembly includes an opening in the at least one contour configured to allow passage to the at least one of the first and second power conductors.

17. The system of claim 16, wherein the opening is located in at least one of a left side and a right side of the electrically insulating molded assembly.

18. The system of claim 16, further comprising an electrically insulating molded boot attached to the electrically insulating molded assembly over the opening.

19. The system of claim 13, wherein the electrically insulating molded assembly is a single injection molded part.
