Abstract: A bus conductor support system includes a tubular bus conductor removably mounted on an insulator assembly in a hollow conductive tubular enclosure. The tubular enclosure is secured to a mounting platform. Access openings are provided in the tubular enclosure for servicing purposes. One end of the insulator assembly is removably secured to the hollow tubular enclosure in a manner which allows easy access thereto through an access opening in the tubular enclosure. The bus conductor is removably mounted on an opposing end of the insulator assembly in a manner which also allows easy access thereto through the same access opening in the tubular enclosure. In one embodiment, a single side access opening in the tubular enclosure is in proximate relation to securing means for the insulator assembly and mounting means for the bus conductor.
