Fig. 1 illustrates an exploded view of a load center assembly of the present invention inGluding a housing and a barrier for interçonnecting therewith;

Detailed Description Referring now to Figs. 1 through ~, an eleGtrical distribution load çenter generally designated as 10 includes a housing 12 and a barrier 14. The housing 12 is formed by a back wall 16 and side walls like 18, 20, and 22. The 2~161639 housing 12 is enclosed ~y a cover or door (not shown) which fits on top of the side walls 1~. The back wall 1~ includes a plurality of holes 24 whiGh are used in surface mounting the housing 12 to a wall. Alternately, the housing 12 may ~e mounted to the studs in a wall or any other mounting arrangement.
The side wall 1~ çontains a plurality of holes like 2~ to allow electrical lines to enter or leave the housing 12. The top 2~ of the side wall has a flange ~0 lwhich extends perpendicularly from the top edge 28 in towards the interior of the housing 12. The flange contains at least one slot 32.
The barrier 14 has a ~enerally flat, thin body ~4 which is supported in a plane parallel to the back wall lÇ.
Connected to one end of the body 34 is an upstanding, L-shaped flange ~6 which extends across the width of the body 34. The flange 36 offsets the body 34 from any cover or door that seals to the top edge 28 of the housing.
Extending outwardly and perpendicular to the body 34 is at least one interlocking tab 38 ~onnected to the L-~haped flange 36. The interloGking tab ~ i5 po~itioned and correspondingly shaped to enga~e the slot ~2 on the side wall 18.
Other means to disengagingly interlock one end of the body 34 are contemplated by the present invention. For example, the edge 40 of the L-shaped flange can be bifurcated to interleaf or sandwich therebetween the flange ~0 of the side wall 18. Alternately, the interlocking tabs .38 engage a slot positioned directly in the side wall 1~.
The housing 12 and the barrier 14 have cooperating interlocking elements so that the two çomponents can be assembled merely by manipulation of the respective components. The interlocking means is designed suGh that the housing 12 and the barrier 14 both of which are - - 2a6~639 generally reGtangular, can be assembled in either of tWQ 180 degree orientations. For example, the barrier 14 can interlock with the slots 3~ located at the other end of the housing 12. Thus, connection with a service line is acçommodated from either end of the housing 12.
The end 42 of the body opposite the interlocking tabs 38 includes ~ntegrally formed legs 44 which extend perpendicular to the body 34 to abut against the baG~ wall 16 of the housing. Each leg 44 has a flange 4Ç connected to the end of the leg which abuts the back wall 16. The flange 4Ç has a hole 43 to threadlngly en~age a fastener such as a screw. The leg 44 supports the end 42 of the ~ody in a parallel position to the back wall lÇ. When the leg 44 is fastened to the back wall lÇ, the interlocking tabs 3~
simultaneously engage and become seGured or locked within the slots 32.
Other means are Gontemplated by the present invention for fastening the opposite end of the body 34 to the housing while simultaneously en~aging the interlocking means and supporting the body 34 in a plane parallel to the ~ack wall lÇ of the housiny. For example, an L-shaped flan~e, similar in description to numeral 3Ç, can extend from the opposite end 42 of the barrier to the top of the side wall 22. The L-shaped flange can then be fastened by conventional means, like a screw, to the side wall 22.
As shown more specifiGally in Fig. 3, the body 34 extends to cover the input terminals SO which are eleçtrically connected to a main circuit breaker generally designated as S2. The service or main electrical lines .54, shown in phantom, enter through the side wall 18 and extend to connect with input terminals SO. Preferably, the body 34 extends to substantially cover the inçoming main lines 54 and the main circuit breaker 52. The body 34 includes an aperture SÇ which allows access to operate the main breaker ~ 2064639 52 vla the handle 58.
The body 34 acts as a barrier between the lnput terminals 50 and the remainder of the components in the housing 12 such as neutral llne connecting bars 60 and output termlnals 62.
Branch circult breakers 64 are mounted within the housing 12 and are electrlcally connected to the output terminals 62 and subsequently to branch lines (not shown) exiting the houslng 12.
Preferably, the support legs 44 have sufflcient wldth to substantlally extend between the slde o~ the main clrcuit breaker 52 and the side wall 22. This provides lsolation of the lncomlng maln llnes 54 from any item which might accidently drop or slide along the side wall 2Z and cause an inadvertent grounding by coming ln contact with the main llnes 54.
The housing 12 and the barrier 14 are preferably made of a corroslon resistant zinc coated sheet metal having an electrostatically deposited palnt finish. Other materials, such as plastic, made be substituted. Details for making an enclosure or housing of a plastlc material are disclosed ln the U.S. Patent No. 5,072,071 (commonly assigned to the Square D Company). Slmllarly, the barrier 14 can be made by in~ection moldlng a plastlc such as Noryl (a reglstered trademark of the General Electrlc Company). A suitable plastlc is preferably rlgid, electrlcally lnsulatlng, and arc or flame retardant.
Whlle particular embodiments and applicatlons of the present appllcations of the present invention has been illustrated and described, it is to be understood that the lnventlon is not limited to the precise construction and composltions disclosed herein and that various modifications, changes, and variations which will be apparent to those skilled in the art may be made ln the ~ ... .
