Abstract
A sectionalized electrical distribution feeder system for carrying electrical power from a source point to a use point or a distribution point. Each section of the distribution system includes a cylindrical enclosure capable of being easily cut with a handsaw. The enclosure also provides support and protection from physical damage to a plurality of electrical conductors that are disposed within the enclosure. The conductors are held firmly in place by a continuous electrically insulating support that snugly fits inside the enclosure. Each conductor can be easily cut with a metal cutting hand saw, and is enclosed in an electrically insulating sheath, a portion of which can be removed from a newly cut end to provide a contact surface. A joint connecting member is provided for electrically connecting the conductors of adjacent sections of the electrical distribution feeder system. The joint connecting member includes a provision for linear expansion of the sections due to normal operating temperatures of the distribution system. A joint cover connects the two adjacent enclosures together and provides additional protection for the joint connecting member.
