Abstract

A serviceable busway plug includes a main body with a main face and two sides, a window, a lever connected to either the main face or the sides, and at least one contact connected to the main body. The contact is configured to electrically connect to a busway.

First claim

What is claimed is:

1. A serviceable busway plug, comprising;
a main body having a main face and two sides;
a window disposed on the main body;
a hook disposed on the main body,
wherein the hook is further configured to lock with a busway;

at least one contact connected to the main body,
wherein the contact is configured to electrically connect to a busway;

a lever connected to one of the main face or one of the two sides,
wherein the lever is configured to open or close an electrical connection with the contact, and
wherein the lever is further configured to cause the hook to slide transversely relative to the main body.

2. The serviceable busway plug of claim 1 , wherein the window includes a bezel.

3. The serviceable busway plug of claim 1 , wherein the window is configured to allow an observer to see the entire electrical connection without opening the serviceable busway plug.

4. The serviceable busway plug of claim 1 , wherein the window is made of a visually translucent material such as glass or transparent composite material.

5. The serviceable busway plug of claim 1 , further including an external indicator attached to the lever, the external indicator configured to indicate when the electrical connection is open or closed.

6. The serviceable busway plug of claim 1 , wherein the at least one contact is a plurality of contacts.

7. The serviceable busway plug of claim 6 , wherein each one of the plurality of contacts is configured to electrically connect to a separate phase of a busway.

8. The serviceable busway plug of claim 1 , wherein the main body is configured to receive one or more power cables electrically connected to equipment.

9. The serviceable busway plug of claim 8 , wherein the lever is configured to selectively electrically connect the one or more power cables to a fuse switch or breaker located within the main body of the serviceable busway plug.

10. A method for checking an electrical connection within a serviceable busway plug, comprising the steps of:
providing a serviceable busway plug containing at least one electrical connection enclosed within the serviceable busway plug and configured to connect to a busway,
wherein the serviceable busway plug has a transparent portion on one surface thereof,
wherein the serviceable busway plug includes a hook configured to be engageable with the busway,
wherein the hook is configured to slide transversely relative to the busway;

observing the electrical connection through the transparent portion of the serviceable busway plug,
wherein the electrical connection within the serviceable busway plug is conducting electricity during the step of observing.

11. The method of claim 10 , wherein the serviceable busway plug further includes a lever configured to toggle power to the electrical connection.

12. The method of claim 11 , wherein during the step of observing, the lever is configured to permit power transfer to the electrical connection.

13. The method of claim 10 , wherein during the step of observing, the serviceable busway plug is sealed from an outside environment.

14. The method of claim 10 , wherein the serviceable busway plug is configured to draw power from the busway via a plurality of contacts.

15. The method of claim 10 , wherein the serviceable busway plug includes a hook engaged with the busway during the step of observing.

16. A serviceable busway plug for use with a busway and a power cable, comprising;
a main body having a main face and two sides;
a window disposed on the main body and configured to allow an observer to see an entire electrical connection between the busway and the power cable without opening the serviceable busway plug.

17. The serviceable busway plug of claim 16 , further comprising a hook configured to lock with the busway.

18. The serviceable busway plug of claim 16 , further comprising a contact configured to electrically connect to the busway.

19. The serviceable busway plug of claim 16 , wherein the window includes a metal bezel extending around a periphery of a transparent central section.

20. The serviceable busway plug of claim 19 , wherein the metal bezel is bolted to the main body.
