Distribution Only Bay
To 218 Circuit Breakers and TPL Fuses
Each distribution only bay has four (4) distribution buses. Each distribution bus has twelve (12) fuse/circuit
breaker device mounting positions. Note that the various fuse/circuit breaker devices require different number
of mounting positions. The load side of each fuse/circuit breaker mounting position is bused to the rear of the
bay. Each fuse/circuit breaker device requires a load lug adapter plate kit that mounts to the appropriate load
side busbars at the rear of the bay (except 1-pole devices). Load return leads are terminated outside the bay to
the optional external ground busbar mounted on top of the bay.
Refer to Figure 96 for load lug landing locations.
When lugs are secured using 3/8 inch hardware, recommended torque is 180 in-lbs when a Belleville lock
washer is used, and 300 in-lbs when a standard flat washer and lock washer are used.
Load Side
Connect load leads to the respective load busbar located at the rear of the bay. These busbars are provided
with 3/8” clearance holes on 1 inch centers for installation of customer provided two hole lugs. Note that for
distribution devices that require more than one distribution mounting positions, lug adapter kits are furnished,
as ordered. The kit-supplied lug adapters are provided with 3/8 clearance holes on 1 inch centers for
installation of customer provided two-hole lugs. The kit also contains 3/8" mounting hardware.
Load Return Side
Load return leads are terminated outside the bay to customer provided return busbars.
