Abstract: A connector for electrically connecting a plurality of electrical conductors of a first busway section to a plurality of electrical conductors of a second busway section. The electrical connection is accomplished by a plurality of pairs of electrical joint connectors, each pair having an independently operable rotational clamping mechanism for clamping that pair of joint connectors tightly to corresponding electrical conductors of the first and second busway sections. An activating cap is used to manually rotate the clamping mechanism between a first and second position. In the first position the pairs of joint connectors are clamped tightly to the busway conductors. In the second position the pairs of joint connectors are loosened permitting an easy insertion or removal of the busway conductors. The pairs of joint connectors of opposite polarity are separated from each other by a phase insulator. Phase insulators also separate the electrical phases from a protective enclosure surrounding the busway.
