Switchgear conductors and mounting arrangements therefor
First Claim
1. A switchgear conductor for engagement by a quick disconnect, said switchgear conductor comprising:
- a stacked pair of elongated flat members having first ends for engagement by said quick disconnect and at least one set of aligned, through apertures adjacent said first ends of said elongated flat members with recesses around each aperture at outer surfaces of said elongated flat members, and at least one fastener extending through said at least one set of aligned through apertures and having enlarged ends fully seated in said recesses.

Abstract
The interface conductors, stabs and runbacks, which are engaged at first ends by quick disconnects on electrical apparatus in a switchgear assembly, are fabricated from a stacked pair of elongated, flat conductors secured together at the first ends by elongated fasteners which are compressed into countersunk through apertures in the flat conductors to form a joint with no lateral projections. The interface conductors are supported adjacent the disconnects by a first support having a base member with through openings in which the conductors are snugly supported, and rigid projections with planar surfaces extending from the base member toward the quick disconnects alongside the openings and against which the interface conductors are secured adjacent free ends of the projections. A second support spaced rearward of the first support provides additional support for the runbacks. Interphase supports formed by C-channels are provided for the runbacks between the first and second supports.

5. A switchgear assembly comprising:
-
a cabinet; at least one electrical apparatus removably mounted in said cabinet and having a set of quick disconnects projecting from a face thereof; conductor supports including a first support extending across and spaced from said set of quick disconnects and having a set of through openings aligned with said set of quick disconnects; and a plurality of buses mounted in said cabinet and including interface conductors having first ends inserted through and supported in said through openings in said first support in position for engagement by said set of quick disconnects, each of said interface conductors comprising a stacked pair of elongated flat members having at least one set of aligned countersunk through apertures adjacent said first end, and a fastener with enlarged ends extending through and fully seated within said at least one set of aligned, countersunk through apertures clamping said free ends of said pair of elongated flat members together. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
