Horizontal hangers
One hanger is provided for every 10 ft (3 m) of horizontally
mounted busway. The type of hanger supplied is determined by
the specific mounting requirements of the busway. (For hook
hangers and angle hangers, see Figure 53 and Figure 54.)
Drop rods 0.50 inch (12.7 mm) diameter are not included and must
be furnished by the installer. Drop rods 0.75 inch (19.1 mm) diameter
are required for seismic applications.
