Distribution Devices
See Distribution Devices and Load Lug Locations - Power/Distribution Bays and Distribution Device and Load
Lug Locations – Distribution Only Bays at the beginning of this section for illustrations of distribution device
and load lug mounting locations.
218 Circuit Breaker Assemblies
Features
♦ Each circuit breaker assembly is equipped with a shunt for MCA load current measurements.
♦ Bolts into bay's distribution device mounting positions.
♦ Load lug adapter plate provides 3/8" clearance holes on 1" centers for installation of customer provided
two-hole lugs. For load return lug requirements, refer to Power/Distribution and Power Only Bays
External Busbars in this section. For the distribution only bays, the load return leads are terminated
outside the bay to customer provided return busbars.
Restrictions
Load should not exceed 80% of device rating.
Refer to Table 1 for required distribution bus mounting positions.
Each distribution bus is divided into half. Each half MUST be populated with distribution devices as shown in
the illustrations at the beginning of this section, without skipping any distribution device mounting positions
within each half.
Four (4) position devices can only be installed in the 1st four or last four positions within each half of a
distribution bus. This is because the lug adapter plate for four (4) position devices can only be installed in
positions starting with the load busbar tops even with each other (not staggered).
Divide distribution equally between rows.
Refer to the illustrations in this section for lug and wire size restrictions.
Load return leads are terminated outside the distribution only bay to customer provided return busbars.
Ordering Notes
1) Order circuit breaker assemblies and load lug adapter kits per Table 1. Load lug adapter kits also contain
the necessary hardware to mount the circuit breakers. For 1-pole circuit breakers in a List 16 Distribution
Only Bay, also order circuit breaker hardware kit P/N 558709. This hardware is used to mount the circuit
breaker.
2) See Table 9 for recommended load distribution wire sizes and lugs.
