Series DPB Busway Installation & Operation Manual
ENERGIZING THE BUSWAY SYSTEM
When the equipment is energized for the first time, qualified personnel should be present. Care should be taken
because if there are any short-circuits and/or ground faults caused by damage or poor installation practices
that are not detected during the "BEFORE ENERGIZING" checklist procedures, serious damage can result when
the power is applied.
The busway should have no electrical load connected or in the ON position when initially energized. Prior to
energization ensure that all devices connected to the busway system are in their OFF position.
Energize the equipment in sequence by starting at the source end and working towards the load.
Energize the main devices, and then the branch-circuit devices. Turn the devices to the ON position.
After all protective devices have been turned on, loads may be turned on.
Occurrence of sparking at any point along the busway is not normal condition. De-energize the
busway immediately. Correct the cause of the sparking condition. Then, conduct an insulation
resistance test before attempting to energize again.
