Electrical distribution system having an improved splice joint between busway sections

摘要

A removable splice joint between two sections of busway constructed to prevent undesired relative movement of the component parts of the joint while also providing interchangeability between component parts and thereby reducing the number of different parts required for assembly of the joint. The joint includes a top cover plate and a bottom cover plate, each with an inclined periphery, a pair of identical outer phase barriers and a plurality of identical inner phase barriers. Each outer barrier includes a pair of ears which are respectively received in associated slots formed in the cover plates. Molded ribs formed on the barriers in cooperation with a square insulating tube which extends between the two outer phase barriers and through each of the inner phase barriers restrict relative movement between component parts of the joint assembly which is captivated by a bolt extending through each of the cover plates as well as each of the barriers. A pull strap connected to the top and bottom cover plates permits the joint to be removed from the side of a busway section permitting selective isolation of a segment of an electrical distribution system.
