The neutral cross bus in a switchgear assembly formed from two sets of side-by-side cabinets includes first and second neutral buses for the respective sets of cabinets. Each neutral bus is made up of a stack of flat conductors oriented horizontally in a main section extending across the cabinets of the set and vertically in a terminal section confronting the terminal section of the other neutral bus. The vertically oriented terminal sections are easily bolted together despite their limited accessibility when the two sets of cabinets are installed side-by-side. The flat conductors of the neutral cross bus are supported in their horizontal main sections by spaced supports formed by planar members with spaced horizontal slots set on edge and mounted by end flanges. The multiple flat conductors of neutral runbacks are interleaved with the flat conductors of the main sections of the cross bus and are supported by partitions having an opening sized to accommodate the maximum number of runback conductors with the remaining portion of the opening blocked by spacers interlocked with each other and the edges of the opening when less than the maximum number of flat runback conductors are used.
