Abstract
The detrimental effects of environmental hazards on units having withdrawable stabs or contacts may be overcome by using fixed feed units in compartments in a manner akin to withdrawable units. In particular, multiple fixed feed units may be provided in a single section or column by implementing vertical bus bars providing multiple connection points particular to fixed feed units. As a result, fixed feed units may be mounted to the vertical bus bars, as opposed to horizontal main bus bars or requiring complex wiring, thereby allowing multiple fixed feed units to be efficiently provided to maximize space. An electrically insulating bus support, which may be supplemented with bracing, may provide improved short-circuit protection. Electrically insulating covers over fixed feed unit connections may also provide electrical isolation in the system in accordance with industry standards. Moreover, in one aspect, fixed feed units and withdrawable units may be intermixed.
