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.

A bus support includes a corona shield portion and a bus support portion on the corona shield portion. The bus support portion includes an insulator engagement ledge including one or more mounting apertures configured to receive a fastener therethrough for mounting the bus support to an insulator. The bus support portion includes first and second bus support walls extending upwardly from opposite sides of the insulator engagement ledge. Each bus support wall includes a U-shaped channel defined therein that is configured to receive and support a cylindrical and/or tubular bus conductor. The corona shield portion and the bus support portion form a monolithic structure.

Provided is a panel board having an insulating plate, and more particularly, a panel board having an insulating plate with improved insulation between bus bars. In a panel board having an insulating plate according to an embodiment, inter-phase part partition walls are formed at an inter-phase part of the insulating plate at a certain gap, thereby increasing an inter-phase creepage distance between mother bus bars, resulting in improving insulation performance.

A bus bar assembly includes multiple bus bars, multiple insulating holders, and a housing. Each of the insulating holders is configured to be mounted to one of the bus bars. Each of the insulating holders includes multiple ribs positioned within an interior cavity of the corresponding insulating holder, and the ribs maintain a desired air gap between each insulating holder and the corresponding bus bar mounted in the insulating holder. The housing is configured to receive each of the bus bars and the corresponding insulating holder.
