2. The electrical distribution apparatus in accordance with Claim 1 further comprising a shield removably coupled to said barrier.
3. The electrical distribution apparatus in accordance with Claim 2, wherein said shield is coupled to said barrier adjacent said first end when said barrier is in the first position and said shield is coupled to said barrier adjacent said second end when said barrier is in the second position.
4. The electrical distribution apparatus in accordance with Claim 2, wherein said barrier includes at least one slot defined thereon to receive said shield therein.
5. The electrical distribution apparatus in accordance with Claim 2, wherein at least one of said barrier and said shield includes an engagement feature arranged to couple said shield to said barrier.
6. The electrical distribution apparatus in accordance with Claim 1, wherein said barrier is hingediy coupled to the portion of said electrical distribution

apparatus such that at least a portion of said barrier is arranged to rotate when said barrier is moved between the first position and the second position.
7. The electrical distribution apparatus in accordance with Claim 1 further comprising at least one cover removably coupled to said barrier, wherein said barrier is further arranged to provide access to a first number of electrical poles coupleable to electrical devices when said at least one cover is removed from said barrier and said barrier is further arranged to provide access to a second number of electrical poles coupleable to electrical devices when said at least one cover is coupled to said barrier, wherein the first number of electrical poles is greater than the second number of electrical poles.
8. The electrical distribution apparatus in accordance with Claim 1 further comprising an engagement feature arranged to removably couple said barrier to the portion of said electrical distribution apparatus.
9. The electrical distribution apparatus in accordance with Claim 8, wherein said barrier further includes a removal feature to facilitate removal of said barrier from said power connector.
10. The electrical distribution apparatus in accordance with Claim 1, wherein said barrier is coupleable to a line side and a load side of said electrical distribution apparatus.
11. A barrier for an electrical distribution apparatus, said barrier comprising an engagement feature to removably couple said barrier to the electrical distribution apparatus, wherein said barrier is selectively adjustable between a first position and a second position, said barrier arranged to prevent insertion of a cable into an opening defined by a first end of a power connector and to permit insertion of the cable into an opening defined by a second end of the power connector when said barrier is in the first position, said barrier arranged to prevent insertion of the cable into the second end opening of (he power connector and to permit insertion of the cable into the first end opening of the power connector when said barrier is in the second position.

12. The barrier in accordance with Claim 11 further comprising a
removal feature arranged to facilitate removal of said harrier from said power connector.
13. The barrier in accordance with Claim 11, wherein said engagement feature is arranged to couple said barrier and said power connector without the use of tools.
14. The barrier in accordance with Claim 11 further comprising a removable shield.
15. The barrier in accordance with Claim 13, wherein said shield is positioned adjacent the first end when said barrier is in the first position, and said shield positioned adjacent the second end when said barrier is in the second position.
16. The barrier in accordance with Claim 11, wherein said shield engages a slot defined in a terminal portion of said barrier.
17. The barrier in accordance with Claim 11 further comprising at least one removable cover, wherein said barrier is further arranged to provide access to a first number of electrical poles coupleable to electrical devices when said at least one cover is removed, wherein said barrier is further arranged to provide access to a second number of electrical poles coupleable to electrical devices when said at least one cover is not removed, and wherein the first number of electrical poles is greater than the second number of electrical poles.
18. A method of assembling an electrical distribution apparatus comprising:
coupling a power connector to a support structure, the power connector including a first end and a second end each defining an opening arranged to receive a cable;
coupling a barrier to the electrical distribution apparatus such that the barrier extends over the power connector; and

adjusting the barrier between a first position and a second position, wherein the barrier is arranged to prevent insertion of the cable into the first end opening and to permit insertion of the cable into the second end opening when the barrier is in the first position, and wherein the barrier is arranged to prevent insertion of the cable into the second end opening and to permit insertion of the cable into the first end opening when the barrier is in the second position.
19. The method in accordance with Claim 18 further comprising coupling the cable to the second end of the power connector when the barrier is in the first position.
20. The method in accordance with Claim 18 wherein adjusting the barrier between a first position and a second position comprises coupling a removable shield to the barrier adjacent one of the first end and the second end.
