Series DPB Busway Installation & Operation Manual
MOUNTING THE BUSRAIL
SUPPORT
When mounting the bus rail please use the supplied hangers that are designed to fit into the top and or side channels found
on each section of bus rail. Each section of bus rail should have at least one hanger and threaded rod assembly with the
maximum span being 5' on centers. 10' and 12' bus rail sections should have a minimum of two hanger and threaded rod
assemblies. Bus Rail lengths longer than 12' should have a minimum of three hangers and threaded rod assemblies. The
span of the hanger and threaded support at a Splice point should be a maximum of 6' on center. Each section of bus rail
needs to be aligned and level. See Figure 5.
NEUTRALS ALIGNMENT
Our busway system is designed so that it is NOT possible to mount the busways if the neutral conductor is not in phase with
one another from section to section. The neutral conductor of each element MUST be aligned on the same side of the sys-
tem. Clear markings are also made on the busway system to ensure proper phasing. See Figure 6.
