WHAT IS CLAIMED IS:
1. An electrical device comprising:
a power connector coupleable to a cable, said power connector including a body defining a first opening and an interior space, wherein said power connector is arranged to receive the cable into the interior space through the first opening; and
a barrier coupled to said power connector to at least partially cover the first opening, said barrier comprising a wall defining a second opening, said wall contacting said body, the second opening arranged to receive the cable therein when the cable is coupled to said power connector.
2. The electrical device in accordance with Claim 1, wherein said barrier further comprises an engagement feature arranged to engage said power connector.
3. The electrical device in accordance with Claim 2, wherein said engagement feature is displaceable when said barrier is coupled to said power connector.
4. The electrical device in accordance with Claim 2, wherein said barrier is coupleable to said power connector without the use of tools.
5. The electrical device in accordance with Claim 3, wherein said barrier is a single piece.
6. The electrical device in accordance with Claim 1, wherein said barrier substantially conforms to a shape of said power connector.
7. The electrical device in accordance with Claim 1 further comprising a reducer removably coupled to said barrier, said.reducer positioned within the second opening for the second opening to receive cables having different sizes.

8. The electrical device in accordance with Claim 1 further comprising a plug removably coupled to said barrier, said plug positioned within the second opening to close the second opening.
9. The electrical device in accordance with Claim 1 further comprising a collar circumscribing the second opening.
10. The electrical device in accordance with Claim 1, wherein said power connector is coupleable to the cable on at least one of a line end and a load end of said electrical device.
11. A barrier for an electrical device, the electrical device including a power connector and a case, the power connector coupleable to a cable, the power connector including a body defining a first opening and an interior space, said barrier comprising:
a wall coupleable to the power connector to at least partially cover the first opening, said wall defining a second opening, wherein said wall is arranged to contact the power connector when said wall is coupled to the power connector, the second opening arranged to receive the cable therein when the cable is coupled to the power connector; and
an engagement feature coupled to said wall, said engagement feature arranged to engage the power connector and couple said wall to the power connector.
12. The barrier in accordance with Claim 10, wherein said engagement feature is displaceable when said wall is coupled to the power connector.
13. The barrier in accordance with Claim 10, wherein said barrier is coupleable to the power connector without the use of tools.
14. The barrier in accordance with Claim 10 further comprising a reducer removably positioned within the second opening for the second opening to receive cables having different sizes.

15. The barrier in accordance with Claim 10 further comprising a plug removably positioned within the second opening to close the second opening.
16. The barrier in accordance with Claim 10 further comprising an outer collar circumscribing the second opening.
17. A method of assembling an electrical device, the method comprising:
providing a power connector including a body defining a first opening, the power connector coupfeable to a cable extending through the first opening;
coupling a barrier to the power connector to at least partially cover the first opening, the barrier including a wall defining a second opening, wherein the wall contacts the body when the barrier is coupled to the power connector; and
aligning the second opening with the first opening, the second opening arranged to receive the cable extending through the first opening.
18. The method in accordance with Claim 17 further comprising coupling the cable to the power connector while the barrier is coupled to the power connector.
19. The method in accordance with Claim 17 further comprising displacing an engagement feature of the barrier when coupling the barrier to the power connector.
20. The method in accordance with Claim 17 further comprising positioning an insert within the second opening of the barrier.
