Busway Connections—
NEMA Type 1
(Non-Qwik Flange) and
NEMA Type 3R
If this style of connection for busway is furnished, the busway “dummy” flanged end
must be removed before installing busway (Figure 22 on page 30).
1. From inside the switchboard, remove the 1/2-in. bolts that fasten the
switchboard bus to the busway dummy nonmetallic flanges. Retain all
hardware for reuse.
2. Remove all screws securing the busway dummy flanged end to the
switchboard enclosure.
3. Remove the busway dummy flanged end (Figure 22).
4. Install the actual busway flanged end to the switchboard bus connectors
provided in the switchboard (Figure 23). Insert the flanges between the
switchboard bus connectors so that the mounting holes in the collar of the
flanged end align with the pre-drilled holes in the switchboard enclosure.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Turn off all power supplying the switchboard and busway before installing
connections.
Failure to follow these instructions will result in death or serious injury.
