NEMA defines a busway as a prefabricated electrical distribution system consisting of bus bars in a protective enclosure, including straight lengths, fittings, devices and accessories. In electric power distribution, a bus duct, or busway, is used to conduct electricity to power cables or cable buses.

Lighter, smaller, easier to modify

ReliaGear® busway replaces the typical wire and conduit in most applications while offering reduced installed costs and improved reliability. Since ReliaGear busway is lighter than wire and conduit it's easier to handle and install. Its compact design is ideal for applications where space is critical and eliminated the time-consuming tasks of stripping, preparing, and pulling wire. All these advantages translate into lower delivery costs, simpler storage and handling, lower total installed costs, and increased space for more equipment.
