INSTALLATION
PRE-INSTALLATION REVIEW
PROPER INSTALLATION OF THE SERIES DPB BUSWAY IS
ESSENTIAL TO THE BUSWAY OPERATION.
Before installing the busway:
1) Conduct an insulation resistance test on each busway device to check for possible
damage during shipment or storage. Ensure the phase-to-phase, phase-to-neutral,
and phase-to-ground isolation.
2) Confirm that the ambient temperature range is within acceptable limits –10°C through +40°C.
If not, please consult the factory for possible de-rating.
3) Ensure that there is sufficient clearance from the walls, ceilings, and load devices.
4) Ensure that the factory-manufactured mounting supports will conform to the recommended
spacing guidelines as detailed in the section titled "Mounting the Busrail".
5) Ensure that all splice connections, end feed units, and tap off boxes will be accessible after
installation.
6) After determining the clearances and the mounting method (vertical or horizontal) for the busway
system, level and align the end feeds and busrails before the final tightening and alignment of all
supporting members.
7) Align the busbar ends of adjoining sections, verifying proper busbar alignment, phasing,
and spacing.
8) Verify that the incoming system phasing, and voltage match the busway system phasing and
rated voltage.
