Available134 products
Busway and bus plugs are prefabricated, movable electrical distribution equipment typically used in commercial and industrial facilities where load locations are likely to change. Busway is an enclosure made up of bus bars to serve as a power source. It is easier to install, replace, and move than cable and conduit. Bus plugs connect to the busway to feed power to the equipment. They use fuses or circuit breakers to protect the electrical circuit from overload. Busway accessories support the installation and connection of busway systems. Busway and bus plugs are only compatible with matching brands.
