Abstract

An electrical distribution apparatus includes a backplane for supporting a plurality of electrical devices, a bus bar assembly coupled to the backplane, and a frame that supports the backplane. The electrical distribution apparatus also includes at least one positioning member that facilitates positioning the backplane relative to the frame. The at least one positioning member at least partially supports the backplane such that the backplane is positionable between a first position and a second position. The backplane contacts the frame in the second position.

First claim

What is claimed is:

1. An electrical distribution apparatus comprising:
a backplane for supporting a plurality of electrical devices;
a bus bar assembly coupled to said backplane;
a frame that supports said backplane; and
at least one positioning member that facilitates positioning said backplane relative to said frame, said at least one positioning member at least partially supporting said backplane such that said backplane is positionable between a first position and a second position, wherein said backplane contacts said frame in the second position;
wherein said backplane comprises a first side edge and a second side edge, said at least one positioning member comprising a first flange and a second flange, said first flange extending from said first side edge and said second flange extending from said second side edge.

2. The electrical distribution apparatus in accordance with claim 1 , wherein said at least one positioning member comprises at least one elongate fastener.

3. The electrical distribution apparatus in accordance with claim 2 , wherein said at least one positioning member extends from said frame, said backplane defining at least one opening that receives said at least one positioning member.

4. The electrical distribution apparatus in accordance with claim 3 , wherein said frame comprises a plurality of vertical rails and at least one horizontal rail, said at least one horizontal rail coupled to an end of each vertical rail of said plurality of vertical rails, said at least one positioning member extending from said at least one horizontal rail.

5. The electrical distribution apparatus in accordance with claim 1 , wherein each of said first flange and said second flange defines a notch that receives a portion of said frame to facilitate positioning said backplane relative to said frame.

6. The electrical distribution apparatus in accordance with claim 1 , wherein said backplane comprises a handle.

7. The electrical distribution apparatus in accordance with claim 1 , wherein said frame includes at least one rail, said at least one rail defining a groove that facilitates aligning said backplane relative to said frame.

8. An electrical distribution system comprising:
an enclosure defining an interior volume;
a plurality of circuit breakers; and
an electrical distribution apparatus positioned at least partially within said interior volume, said electrical distribution apparatus comprising:
a backplane supporting said plurality of circuit breakers;
a bus bar assembly coupled to said backplane and to said plurality of circuit breakers;
a frame that supports said backplane within said interior volume; and
at least one positioning member that facilitates positioning said backplane relative to said frame, said at least one positioning member at least partially supporting said backplane such that said backplane is positionable between a first position and a second position, wherein said backplane contacts said frame when said backplane is in the second position;
wherein said backplane comprises a first side edge, a second side edge, a first flange, and a second flange, said first flange extending from said first side edge, said second flange extending from said second side edge, wherein each of said first flange and said second flange defines a notch that facilitates positioning said backplane relative to said frame.

9. The electrical distribution system in accordance with claim 8 , wherein said at least one positioning member comprises at least one elongate fastener extending from said frame, said backplane defining at least one opening that receives said at least one positioning member.

10. The electrical distribution system in accordance with claim 8 , wherein said first flange comprises a first handle and said second flange comprises a second handle.

11. The electrical distribution system in accordance with claim 8 , wherein said frame comprises a first rail, said first rail defining a groove that facilitates aligning said backplane relative to said frame.

12. The electrical distribution system in accordance with claim 11 , wherein said frame comprises a second rail parallel to said first rail, said at least one positioning member including a plurality of elongate fasteners extending from said second rail.
