Abstract
Abstract A system of components which can be grouped into sets for assembly in various configurations to provide electrical neutral bar assemblies of different shapes and having different numbers of neutral-wire-receiving openings. The system, which is particularly suitable for use with neutral wires of relatively large ampacity, includes a plurality of insulating bases, a plurality of neutral bars of different lengths, and an interconnecting plate. One or more of the bases and one or more of the neutral bars with or without the interconnecting plate are arranged to be secured together in different configurations by bolts.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
223 words
A system of neutral bar assembly components capable of being grouped in various quantities into sets for construction of neutral bar assemblies of various configurations, said components comprising a plurality of identical relatively short neutral bars, a plurality of identical relatively long neutral bars, a conductive plate upon which the neutral bars may be mounted in side-by-side relation, and a plurality of insulating bases, securing means for securing the plate on a pair of the bases, securing the short neutral bars either singly directly on a base or in side-by-side relation directly on the plate, and for securing the long neutral bars either singly directly on a base, in side-by-side relation directly on the plate, or in stacked relation respectively on the short neutral bars, each of the neutral bars having wire-receiving openings in its end walls, respectively, and each having screw-receiving openings in its top wall intersecting the respective wire-receiving openings, screw threaded into the screw-receiving openings, respectively, and access openings extending through each of the long neutral bars positioned so as to be in alignment respectively with the screwreceiving openings of the relatively short neutral bars when any one of the long neutral bars is secured by the securing means in stacked relation on any one of the short neutral bars thereby to expose the screws for access by a tool.
Claim 2
Independent Claim
223 words
A system of neutral bar assembly components capable of being grouped in various quantities into sets for construction of neutral bar assemblies of various configurations, said components comprising a plurality of identical relatively short neutral bars, a plurality of identical relatively long neutral bars, a conductive plate upon which the neutral bars may be mounted in side-by-side relation, and a plurality of insulating bases, securing means for securing the plate on a pair of the bases, securing the short neutral bars either singly directly on a base or in side-by-side relation directly on the plate, and for securing the long neutral bars either singly directly on a base, in side-by-side relation directly on the plate, or in stacked relation respectively on the short neutral bars, each of the neutral bars having wire-receiving openings in its end walls, respectively, and each having screw-receiving openings in its top wall intersecting the respective wire-receiving openings, screw threaded into the screw-receiving openings, respectively, and access openings extending through each of the long neutral bars positioned so as to be in alignment respectively with the screwreceiving openings of the relatively short neutral bars when any one of the long neutral bars is secured by the securing means in stacked relation on any one of the short neutral bars thereby to expose the screws for access by a tool.
Claim 3
Dependent Claim
123 words
A neutral bar assembly comprising an insulating base, a relatively short neutral bar of rectangular cross section mounted on the base, a relatively long neutral bar of rectangular cross section mounted on the short neutral bar, securing means securing the base and the neutral bars together in fixed relation, each of the neutral bars having wire-receiving openings in its opposite end walls, respectively, and each having screw-receiving openings in its upper wall intersecting the wire-receiving openings, access openings extending through the long neutral bar and positioned in vertical alignment with the respective wire-clamping screws of the relatively short neutral bar, when the bars are secured in said fixed relation by the securing means, thereby to expose the screws for access by a tool.
Claim 4
Dependent Claim
123 words
A neutral bar assembly comprising an insulating base, a relatively short neutral bar of rectangular cross section mounted on the base, a relatively long neutral bar of rectangular cross section mounted on the short neutral bar, securing means securing the base and the neutral bars together in fixed relation, each of the neutral bars having wire-receiving openings in its opposite end walls, respectively, and each having screw-receiving openings in its upper wall intersecting the wire-receiving openings, access openings extending through the long neutral bar and positioned in vertical alignment with the respective wire-clamping screws of the relatively short neutral bar, when the bars are secured in said fixed relation by the securing means, thereby to expose the screws for access by a tool.
Claim 5
Dependent Claim
34 words
A neutral bar assembly as in claim 2 wherein each of the neutral bars is tubular having a longitudinal opening and wherein opposite end portions of the longitudinal opening respectively define the wire-receiving openings.
Claim 6
Dependent Claim
34 words
A neutral bar assembly as in claim 2 wherein the securing means includes a tapped opening in one of the neutral bars and a bolt having a threaded portion received in said tapped opening.
Claim 7
Dependent Claim
105 words
A neutral bar assembly as in claim 2 wherein the securing means includes a pair of longitudinally spaced transverse openings extending through the relatively short neutral bar from the bottom wall to the top wall thereof, and a pair of longitudinally spaced transverse openings in the relatively long neutral bar one of which extends inwardly of the bar from the bottom wall and the other of which extends through the bar from the bottom wall to the top wall thereof, the transverse openings of the relatively short neutral bar being spaced the same distance apart as the transverse openings of the relatively long neutral bar.
Claim 8
Dependent Claim
47 words
A neutral bar assembly as in claim 5 wherein one of the transverse openings in the relatively short neutral bar and said one transverse opening in the relatively long neutral bar are threaded only at the respective portions thereof near the lower walls of the respective bars.
Claim 9
Dependent Claim
30 words
A neutral bar assembly as in claim 5 whereIn each of the longitudinally spaced transverse openings in the bars is equally spaced from a transverse centerline of its respective bar.
Claim 10
Dependent Claim

A neutral bar assembly as in claim 2 wherein the securing means comprises transverse bolt-receiving openings in the base and bars, respectively, which are aligned when the base and bars are positioned to be secured in said fixed position, and a bolt received in the aligned openings with a lower threaded portion of the bolt threaded into the opening in the relatively short neutral bar.
Claim 11
Dependent Claim
66 words
A neutral bar assembly as claimed in claim 8 wherein the securing means comprises transverse bolt-receiving openings in the base and bars, respectively, which are aligned when the base and bars are positioned to be secured in said fixed position, and a bolt received in the aligned openings with an upper threaded portion of the bolt threaded into the opening in the relatively long neutral bar.
Claim 12
Dependent Claim
