Abstract

An auxiliary generator connection, a method of operating and a system are disclosed. The auxiliary generator connection includes at least one first conductor coupled to a first portion of the electrical utility distribution network. At least one second conductor is coupled to a second portion of the electrical utility distribution network. A t-type connector is coupled between the at least one first conductor and the at least one second conductor. A switch is coupled between the at least one second conductor and the t-type connector. A generator conductor is electrically coupled at a first end to the t-type connector. A generator plug is coupled to a second end of the generator conductor opposite the t-type connector.

First claim

What is claimed is:

1. An auxiliary generator connection for an electrical utility distribution network, the connection comprising:
at least one first conductor coupled to a first portion of the electrical utility distribution network;
at least one second conductor coupled to a second portion of the electrical utility distribution network;
a t-type connector coupled between the at least one first conductor and the at least one second conductor;
a switch coupled between the at least one second conductor and the t-type connector;
a generator conductor electrically coupled at a first end to the t-type connector; and
a generator plug coupled to a second end of the generator conductor opposite the t-type connector.

2. The connection of claim 1 , wherein the t-type connector includes a body and an elastomeric submersible outer layer.

3. The connection of claim 2 wherein the generator conductor is a 500 kCMIL welding cable having a length of 1 foot to 5 feet.

4. The connection of claim 3 wherein the generator plug is a camlock type generator plug.

5. The connection of claim 4 wherein the elastomeric outer layer is made from rubber.

6. The connection of claim 4 wherein the t-type connector is configured to operate at 120V, 600 amp continuous rating with a 50 KA peak short circuit rating.

7. The connection of claim 1 further comprising a crab joint coupled to the at least one first conductor.

8. The connection of claim 1 further comprising a cap member operably coupled to the generator plug, wherein the generator plug is configured to be submersible when the cap is installed on generator cam lock device which is attached to the plug.

9. A method of connecting an auxiliary electrical generator to an electrical utility distribution network, the method comprising:
providing a t-type connection between a first conductor coupled to a first portion of the electrical utility distribution network and a second conductor coupled to a second portion of the electrical utility distribution network;
providing a generator cable coupled on a first end to the t-type connector and generator plug on a second opposing end of the generator cable;
providing a switch between the t-type connector and the second conductor;
actuating the switch to isolate the first portion of the electrical utility distribution network from the second portion of the electrical utility distribution network;
coupling the generator plug to an auxiliary electrical generator; and
generating electrical power with the auxiliary electrical generator.

10. The method of claim 9 wherein the t-type connector includes a body and an elastomeric outer layer.

11. The method of claim 10 wherein the elastomeric outer layer is made from rubber.

12. The method of claim 10 wherein the generator plug is a cam lock type plug.

13. The method of claim 12 wherein the t-type connector is configured to operate at 30 kV, 600 amp continuous rating with a 50 KA peak short circuit rating.

14. The method of claim 13 wherein the generator conductor is a 500 kCMIL welding cable having a length of 1 foot to 5 feet.

15. The method of claim 9 further comprising providing a crab joint coupled to the at least one first conductor.

16. The method of claim 9 further comprising installing a cap on generator plug to form a water tight seal.

17. A system for connecting an auxiliary electrical generator to an electrical utility distribution network, the system comprising:
a crab joint configured to electrically couple to a first portion of the electrical utility distribution network;
a t-type connector electrically coupled to the crab joint, the t-type connector being configured to operate at 30 kV, 600 amp continuous rating with a 50 KA peak short circuit rating;
a switch electrically coupled to the t-type connector opposite the crab joint, the switch configured to electrically couple to a second portion of the electrical utility distribution network;
a first generator conductor electrically coupled on a end to a first arm of the t-type connector;
a second generator conductor electrically coupled on an end to a second arm of the t-type connector;
a first generator plug coupled to the first generator conductor on an end opposite the t-type connector; and
a second generator plug coupled to the second generator conductor on an end opposite the t-type connector.

18. The system of claim 17 wherein the t-type connector includes a copper body and a rubber outer layer.

19. The system of claim 18 wherein the first generator conductor and the second generator conductor are a 500 kCMIL welding cable having a length of 1 foot to 5 feet.

20. The connection of claim 19 further comprising a cap operably coupled to the first generator plug, wherein the first generator plug and the cap cooperate to form a water tight seal of the first generator plug when the cap is installed on cam lock device which is attached to the first generator plug.
