Busway, which houses bar-style aluminum or copper conductors in a grounded metal enclosure, offers a component-based approach to power distribution that assembles quickly using basic tools. Feeder-style busway is especially helpful for longer runs connecting electrical power between different pieces of equipment.

Unlike plug-in busway, feeder designs are strictly a point-A-to-point-B solution. However, they offer a labor-saving alternative to cable and conduit for such applications as connecting a transformer to switchgear, or connecting multiple switchgear units to each other. It also can be combined with plug-in busway for larger installations, as Eduardo Miller, offer marketing manager with Schneider Electric explains.

“Feeder busway can be used to distribute electrical power from this same type of equipment to a point where you need to distribute it to multiple locations,” he says. “At this point, plug-in busway, in combination with bus plugs, can easily be connected to the feeder busway to distribute the electrical power to those locations.

Feeder busway isn’t just for high-amperage electrical systems, despite what some electrical contractors might think. Though it serves industrial applications well, it can also be useful in high-rise office towers, as a way to distribute power from a lower-level electrical room up to the highest floors. Manufacturers have developed a full range of elbow- and T-connectors to direct busway around corners, poles and other obstructions.

“Busway allows maximum flexibility, space savings due to its compact design, reduced installation time and lower install cost,” Miller says, comparing both feeder and plug-in products to traditional cable and conduit approaches. “Additionally, busway does not require the use of specialized tools and requires little maintenance.”
