Abstract
Abstract A load center is constructed with line busing disposed entirely between the circuit breakers, without adding depth to the load center enclosure, and positioned to be engaged by circuit breakers that are locked into position by pivoting thereof in planes parallel to the rear wall of the enclosure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
176 words
A loadcenter comprising a plurality of circuit breakers and a panelboard mounting said circuit breakers; each of said circuit breakers including a relatively flat rectangular case with line and load terminals at opposite ends thereof and a contact operating handle projecting through an aperture in a narrow top wall of said case which extends between sidewalls of the case that are many times larger in area than the area of the top wall; said panelboard including a shallow rectangular housing comprising a rear wall and a front wall closely spaced with respect to said rear wall; line busing means mounted within said housing and insulated therefrom; mounting means within said housing; said mounting means operatively positioning said plurality of circuit breakers within said housing with said sidewalls disposed in planes extending generally parallel to said rear wall; said operating handles disposed behind said front wall and said line terminals electrically connected to said line busing means; said front wall having opening means through which said operating handles are engageable for manual operation of said circuit breakers.
Claim 2
Dependent Claim
176 words
A loadcenter comprising a plurality of circuit breakers and a panelboard mounting said circuit breakers; each of said circuit breakers including a relatively flat rectangular case with line and load terminals at opposite ends thereof and a contact operating handle projecting through an aperture in a narrow top wall of said case which extends between sidewalls of the case that are many times larger in area than the area of the top wall; said panelboard including a shallow rectangular housing comprising a rear wall and a front wall closely spaced with respect to said rear wall; line busing means mounted within said housing and insulated therefrom; mounting means within said housing; said mounting means operatively positioning said plurality of circuit breakers within said housing with said sidewalls disposed in planes extending generally parallel to said rear wall; said operating handles disposed behind said front wall and said line terminals electrically connected to said line busing means; said front wall having opening means through which said operating handles are engageable for manual operation of said circuit breakers.
Claim 3
Dependent Claim
36 words
A loadcenter as set forth in claim 1, in which a first and a second of said circuit breakers are positioned with their bottom walls in confronting relationship and the handles thereof projecting in opposite directions.
Claim 4
Dependent Claim
31 words
A loadcenter as set forth in claim 1, in which a first and a second of said circuit breakers are positioned with the line terminal end walls thereof in confronting relationship.
Claim 5
Dependent Claim
34 words
A loadcenter as set forth in claim 1, in which the mounting means includes hook portions about which the circuit breakers are pivoted in planes parallel to said rear wall into their operative positions.
Claim 6
Dependent Claim
41 words
A loadcenter as set forth in claim 4, in which the busing means includes generally planar portions constituting stabs; said line terminals of said circuit breakers being frictionally engaged with said stabs; said planar portions positioned parallel to said rear wall.
Claim 7
Dependent Claim
41 words
A loadcenter as set forth in claim 5, in which said busing includes first and second identical conducting straps, each having a main portion and an offset portion at the end of said main portion; said offset portions constituting said stabs.
Claim 8
Dependent Claim
36 words
A loadcenter as set forth in claim 6, in which said main portions are aligned with each other and disposed in a common plane, said offset portions disposed parallel to said plane on opposite sides thereof.
Claim 9
Dependent Claim
31 words
A loadcenter as set forth in claim 7, in which said offset portions are in alignment, a wire grip means mounted to each of said main portions at its other end.
Claim 10
Dependent Claim
32 words
A loadcenter as set forth in claim 7, in which each of said offset portions provides a sufficient number of said stabs for frictional engageMent by line terminals of four circuit breakers.
Claim 11
Dependent Claim
25 words
A loadcenter as set forth in claim 9, in which said offset portions are in alignment and said plane is parallel to said rear wall.
