Installing Indoor Busway
Horizontal Mounting
Overhead Support
For overhead-supported busway, 1/2-inch drop
rods are recommended with a maximum 10-foot
spacing. Drop rods and other hardware must be
furnished by the installer. Figure 3 illustrates
mounting dimensions for typical installations.
• Maintain good alignment of the drop rods
along the busway run.
• Do not support busway at the joints.
• After the busway is secured in the hangers,
adjust the hangers on the rods for the correct
elevation.
• Sway braces (furnished by the installer) may be
required to keep the run straight or to prevent
rotation.
Wall or Column Support
Single-rod hangers, as shown in Figure 4, may be
used for mounting busway on walls or columns
with the addition of an angle support supplied by
the installer.

installations.

flat and (b) mounted edgewise.
Vertical Mounting
Support Busway on maximum 16-foot centers.
Use Table 7 to determine the number of springs
required based on busway weight, as listed in
Table 4, Table 5 and Table 8. Select the spring
hanger based on the seismic load; amperage and
Vertical support spacing mentioned in table 1 & 2.

amperage.

After placing the length of busway through
the floor, follow this procedure to assemble
hangers to the busway, as illustrated in Figure 5
Figure 6 & 6A. For convenience in assembly, step 8
may be completed before the hangers are
attached to the busway.
NOTE: Check that the initial height is 8 inches, as
shown in Figure 6.
NOTE: Veuillez vous assurer que la hauteur
initiale est de 8 pouces, tel que montré à la Figure

1. Loosen the hanger bolt A, shown in Figure 5.
2. Assemble the hangers to each side of the
busway.
3. Position the hangers on the busway so that
the base channel (B) rests on the floor or other
support. A floor flange (C) may be placed under
the hanger, but it will not support the busway
weight.
4. Fit the hanger clamps (G) to the busway
housing and hand tighten the hanger bolts (A).
5. Anchor the base channels to their supports.
6. Tighten the hanger bolts (A).
