5. The arc chute assembly of claim 1 , wherein said divider wall has a height less than a height of at least one of said side walls.
6. The arc chute assembly of claim 1 , wherein said arc plate area has a width that extends between said side walls.
7. The arc chute assembly of claim 6 , wherein said first sub-arc area and said second sub-arc each have a width less than the width of said arc plate area.
8. The arc chute assembly of claim 1 , wherein said first sub-arc area and said second sub-arc area are substantially the same size.
9. The arc chute assembly of claim 1 , wherein said notch comprises a substantially rectangular profile.
10. The arc chute assembly of claim 1 , wherein said at least one arc plate comprises a plurality of substantially similar arc plates.
11. A power distribution system comprising:
a housing having a first wall, a second wall and a pair of side walls coupled to said first wall, said first wall and said side walls configured to form an arc area, the housing further having a divider wall coupled to said first wall between said side walls, said divider wall configured to form a first sub-arc area, a second sub-arc area, and an arc plate area, said first sub-arc area and said second sub-arc area configured to be in flow communication with said arc plate area;
a support coupled to said first wall and said side walls;
at least one arc plate coupled to said support, said arc plate having a body extending between said side walls and over said divider wall, said at least one arc plate comprising a notch configured to receive at least a portion of said divider wall; and
a circuit breaker coupled to said housing and having a first sub-pole coupled within said first sub-arc area and a second sub-pole coupled within said second sub-arc area.
12. The power distribution system of claim 11 , wherein said at least one arc plate includes a first end coupled to said support adjacent one said side wall and a second end coupled to said support adjacent another said side wall.
13. The power distribution system of claim 11 , wherein said at least one arc plate is positioned over said first sub-arc area and said second sub-arc area.
14. The power distribution system of claim 11 , wherein said at least one arc plate includes a first recess positioned over said first sub-arc area and a second recess positioned over said second sub-arc area.
15. The power distribution system of claim 14 , wherein said notch is between said first recess and said second recess.
16. The arc chute assembly of claim 11 , wherein said divider wall has a height less than a height of at least one of said side walls.
17. The power distribution system of claim 11 , wherein said arc plate area is configured to distribute gas pressure formed in said first sub-arc area and said second sub-arc area.
18. A method of manufacturing an arc chute assembly, the method comprising:
forming a housing having a first wall, a second wall, and a pair of side walls coupled to the first wall, said walls configured to form an arc area;
positioning a divider wall between the side walls, the divider wall configured to form a first sub-arc area, a second sub-arc area, and an arc plate area within the housing;
forming a notch in at least one arc plate; and
coupling the at least one arc plate to the housing such that the notch receives at least a portion of the divider wall, the at least one arc plate having a body extending between the side walls and over the divider wall.
19. The method of claim 18 , wherein forming the divider wall comprises forming the first sub-arc area and the second sub-arc area in flow communication with the arc plate area.
20. The method of claim 18 , wherein coupling the at least one arc plate to the housing comprises positioning a first recess of the at least one arc plate over the first sub-arc area and positioning a second recess of the at least one arc plate over the second sub-arc area.
