How are plug-in busways suspended?
What will be an ideal response?
There is an almost unlimited selection of methods for hanging or supporting the plug-in busway. Common support arrangements are built around the use of clamp hangers. Prefabricated clamp hangers eliminate the drilling, cutting, or bending generally associated with hangers constructed on the job. Clamp hanger halves are slipped over the duct casing and are bolted together. Support arrangements shown include bracket supports, strap hangers, rod hangers, and messenger cable suspension
