Distribution Only Bay
To 218 Circuit Breakers and TPL Fuses
Each Distribution 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 4-12 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.
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
