Where it sits in the power path
Feeder and plug-in busway that carries high current between equipment and out to the loads.
Product lines
Feeder busway
Point-to-point power between transformers, switchgear and large loads.
Plug-in busway
Outlets along the run for rising mains, production lines and data halls.
Plug-in units
Fusible and breaker units that tap power anywhere along a plug-in run.
Feeder or plug-in?
| Feeder busway | Plug-in busway | |
|---|---|---|
| Purpose | Moves power between two pieces of equipment | Distributes power to loads along its length |
| Outlets | None | At regular intervals for plug-in units |
| Typical runs | Transformer to switchgear, switchgear to switchgear | Rising mains in towers, production lines, data halls |
| Changing loads later | Re-routing needs new sections | Add or move loads by plugging in units |

Questions
What should I include in a busway inquiry?
The current rating, system voltage, available fault current (the short-circuit rating required), conductor preference, a route drawing or plan with lengths, and the number of elbows, tees and plug-in units. Mark where the run connects to transformers or switchgear.
Which standards apply?
Busway in Canada is certified to CSA C22.2 No. 27. Projects in the United States use UL 857.
