1. An electrical device, coupleable to a cable, the electrical device comprising:

a power connector coupleable to the cable, said power connector defining an interior space and a cable opening, said power connector arranged to receive the cable into the interior space through the cable opening;

a barrier removeably coupled to the power connector and arranged to at least partially cover the cable opening, said barrier comprising (i) an inner collar having a first opening and (ii) an outer collar having a second opening larger than said first opening, each of said inner collar and said outer collar arranged to receive at least a portion of the cable therethrough, wherein said outer collar circumscribes said inner collar; and

a reducer removably coupled to said barrier, said reducer positioned within said first opening, the reducer defining a third opening therethrough, the third opening being smaller the the first opening.

2. The electrical device in accordance with claim 1 , wherein said barrier further comprises a wall disposed opposite the power connector, the wall at least partly forming said inner collar, and wherein said outer collar extends from said wall.

3. The electrical device in accordance with claim 2 , wherein said first opening is sized to receive only an un-insulated portion of the cable therethrough, and wherein said second opening is sized to receive an insulated portion of the cable therethrough.

4. The electrical device in accordance with claim 1 , wherein said first opening is circular and has a first diameter, and wherein said second opening is circular and has a second diameter larger than the first diameter.

5. The electrical device in accordance with claim 1 further comprising a plug removably coupled to said barrier, said plug positioned within said first opening to close said first opening.

6. The electrical device in accordance with claim 1 , wherein said barrier is a single piece.

7. The electrical device in accordance with claim 1 , wherein said barrier inhibits an operator contacting said power connector through said first opening when said power connector is coupled to the cable.

8. The electrical device in accordance with claim 1 , wherein said barrier further comprises a plurality of inner collars and a plurality of outer collars such that said barrier is arranged to receive a plurality of cables coupled to said power connector.

9. The electrical device in accordance with claim 1 , wherein said barrier is removably coupled to at least one of a line end and a load end of the power connector.

10. The electrical device in accordance with claim 1 , wherein the barrier surrounds the power connector.

11. The electrical device in accordance with claim 1 , wherein the barrier conforms to the peripheral shape of the power connector.

12. The electrical device in accordance with claim 1 , wherein the barrier does not increases the footprint of the electrical device.

13. A barrier for an electrical device, the electrical device including a power connector coupleable to a cable, the power connector defining a cable opening to receive the cable therein, said barrier comprising:

an engagement feature to removeably couple the barrier to the power connector;

a wall disposed opposite the power connector, and arranged to cover at least a portion of the cable opening;

an inner collar defining a first opening arranged to receive at least a portion of the cable, said inner collar at least partly formed by said wall;

an outer collar defining a second opening larger than said first opening, arranged to receive at least a portion of the cable, wherein said outer collar circumscribes said inner collar; and

an insert removably coupled to said barrier, said insert positioned within said first opening, the insert defining a third opening therethrough, the third opening being smaller than the first opening.

14. The barrier in accordance with claim 13 wherein said wall is arranged such that said inner collar is aligned with the cable opening of the power connector.

15. The barrier in accordance with claim 14 , wherein said outer collar comprises a ring extending from said wall.

16. The barrier in accordance with claim 13 , wherein said first opening is circular and has a first diameter, and wherein said second opening is circular and has a second diameter larger than the first diameter.

17. The barrier in accordance with claim 13 , wherein the engagement feature comprises at least one of (i) a stop to abut against a portion of the power connector when the barrier is coupled to the power connector and (ii) a guide feature to facilitate positioning of the barrier relative to the power connector in an installation direction.
