Abstract
Abstract A bus bar interconnection arrangement for stackable electrical panels includes bus bars mounted along the rear wall of a panel enclosure with the bar ends bent forward along the side walls of the enclosure. Openings in the side walls expose the bar ends to permit mating engagement and direct contact connection with complementary bar ends of a bus bar of an adjacent panel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
A bus bar interconnection arrangement for stackable electrical panels comprising: a box enclosure including a rear wall and opposing side walls extending forward from said rear wall, each of said side walls of said enclosure having openings exposing the interior of said enclosure; a bus bar having a main body part supported on said rear wall and extending between said side walls; said bus bar further including end parts bent forward from said main body part disposed in a substantially coplanar relationship with said opposing side walls within said openings, whereby when said enclosure is mounted in stacked relationship with another enclosure having said bus bar interconnection arrangement an end of said bus bar registers in direct mutually engaging relationship with an end of a bus bar of an adjacent enclosure; and fastener means engaging the bus bar ends such that said bus bar ends are clamped together in electrically conducting relationship with other bus bars when said box enclosure is mounted in stacked relationship with other enclosures.
Claim 2
Dependent Claim
168 words
A bus bar interconnection arrangement for stackable electrical panels comprising: a box enclosure including a rear wall and opposing side walls extending forward from said rear wall, each of said side walls of said enclosure having openings exposing the interior of said enclosure; a bus bar having a main body part supported on said rear wall and extending between said side walls; said bus bar further including end parts bent forward from said main body part disposed in a substantially coplanar relationship with said opposing side walls within said openings, whereby when said enclosure is mounted in stacked relationship with another enclosure having said bus bar interconnection arrangement an end of said bus bar registers in direct mutually engaging relationship with an end of a bus bar of an adjacent enclosure; and fastener means engaging the bus bar ends such that said bus bar ends are clamped together in electrically conducting relationship with other bus bars when said box enclosure is mounted in stacked relationship with other enclosures.
Claim 3
Dependent Claim
67 words
A bus bar interconnection arrangement as set forth in claim 1 wherein said bus bar includes a first end having a hole opening and a second end having a hole opening including an internally threaded portion coaxially aligned with said hole opening of said first end, and said fastener means includes a screw having a clearance fit through said hold opening of said first bus bar end.
Claim 4
Dependent Claim
47 words
A bus bar interconneCtion arrangement as set forth in claim 2 wherein said enclosure includes a barrier for separating said second end of said bus bar from access from within said enclosure and said first end of said bus bar is freely accessible from within said enclosure.
Claim 5
Dependent Claim
52 words
A bus bar interconnection arrangement for a stackable electrical panel as set forth in claim 3 wherein said enclosure houses a multimeter center and includes first and second separated compartments, and said barrier is located in one of said first and second compartments to separate said bus bar from the one compartment.
