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.

Abstract: A flexible arrangement for providing secondary terminations, such as for switchgear in electric power distribution systems, includes a plurality of molded blocks each having at least one pair of oppositely directed hooks extending from a rear face. The hooks pass through complimentary notches in a mounting slot in a mounting panel, and engage the mounting panel with the molded blocks displaced along the mounting slot so that the hooks are out of registration with the notches. A locking member blocks the realignment of the hooks with the notches. Molded filler blocks without the terminal members can be substituted for one or more molded terminal blocks when fewer terminations are needed. There filler blocks have hand grips such as preferably a longitudinal rib molded on a front face, for inserting and removing the filler block from the slot.

Abstract: An electrical shorting block has a molded body with a plurality of side-by-side recesses in which terminal members having first, tapped apertures are secured. A shorting bar supported in the molded body extends across but is spaced from the terminal numbers and has second apertures aligned with the first apertures. For the hot side terminal members, shorting connectors slidable through but captured by the apertures in the shorting bar have threaded ends which can be selectively threaded into the tapped first apertures of those terminal members. Helical compression springs bias the captured shorting connectors away from the terminal members when not used to short the terminal. Common terminal members are connected to the shorting bar by shorting screws which remain threaded into the first apertures. The terminal members preferably have both screw terminations and male fast-on terminations.
