Abstract
Abstract Double-lug wiring assemblies are added to multipole electric circuit breaker load centers to allow for loop-feed connection between the load centers when employed within satellite power take-off facilities. The loop-feed arrangement results in a substantial savings in wire costs and installation time.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A load center comprising: an insulative support; a line terminal lug attached to said support; a first lug electrically connected to said line terminal lug on one side of said line terminal lug and arranged for electrically connecting with a first conductor; a second lug electrically connected to said line terminal lug on an opposite side of said line terminal lug and arranged for electrically connecting with a second wire conductor; and a neutral bar including an elongated perimetrically closed tubular conductor having a pair of neutral lugs electrically connected thereto and arranged for electrically connecting with a third and fourth wire conductor, said first lug being attached to a Z-shaped strap, said Z-shaped strap terminating in a pair of offset ends wherein one of said offset ends is attached to said first lug and the other of said offset ends is electrically connected with said line terminal lug.
Claim 2
Dependent Claim
149 words
A load center comprising: an insulative support; a line terminal lug attached to said support; a first lug electrically connected to said line terminal lug on one side of said line terminal lug and arranged for electrically connecting with a first conductor; a second lug electrically connected to said line terminal lug on an opposite side of said line terminal lug and arranged for electrically connecting with a second wire conductor; and a neutral bar including an elongated perimetrically closed tubular conductor having a pair of neutral lugs electrically connected thereto and arranged for electrically connecting with a third and fourth wire conductor, said first lug being attached to a Z-shaped strap, said Z-shaped strap terminating in a pair of offset ends wherein one of said offset ends is attached to said first lug and the other of said offset ends is electrically connected with said line terminal lug.
Claim 3
Dependent Claim
25 words
The load center of claim 1 wherein said pair of neutral lugs are each offset from each other and are arranged in the same plane.
Claim 4
Dependent Claim
16 words
The load center of claim 1 wherein said second lug is attached to a planar strap.
Claim 5
Dependent Claim
31 words
The load center of claim 3 wherein said second lug is attached to one end of said planar strap and said line terminal lug is electrically connected to said other end.
