  • Patent number: 10707631
    Abstract: A busway assembly includes first and second busway sections and a joint assembly connecting the first and second sections. Each busway section includes a housing including first and second opposing side portions. Each busway section includes a first insulator held in the first side portion and a second insulator held in the second side portion. The first and second insulators each hold one or more bus bar conductors. The joint assembly includes first and second connected joint housings and plurality of joint conductors held in the first and second housings. A first exposed portion of each joint conductor extends out of the first housing and is electrically connected with one of the bus bar conductors of the first busway section. A second exposed portion of each joint conductor extends out of the second housing and is electrically connected with one of the bus bar conductors of the second busway section.
