Busway
Busways can be a part of electrical service entrance equipment; usually in large industrial or
commercial applications. Table 5.13 lists common codes, standards, and recommended
practices associated with busways. The NEC establishes criteria for the use of busways in
Article 368 Busways. It defines a busway as:
A grounded metal enclosure containing factory-mounted bare or insulated conductors, which
are usually copper or aluminum bars, rods, or tubes. [21]
IEEE 141 [22] lists four types of busway, including:
Feeder busway
Plug-in busway
Lighting busway
Trolley busway
Feeder busways generally have an available current range to 6000 A, at 600 VAC.
