Distribution Devices and Load Lug Locations - Power/Distribution Bays
Each Power/Distribution Bay has two (2) distribution buses. Each distribution bus has twenty-four (24)
fuse/circuit breaker device mounting positions. Note that the various fuse/circuit breaker devices require
different number of mounting positions, as detailed in the following sections. Note also that each distribution
bus is divided into half, and each half MUST be populated with distribution devices from left-to-right, without
skipping any distribution device mounting positions within each half. The load side of each fuse/circuit
breaker mounting position is bused up to the top of the bay. Each fuse/circuit breaker device requires a load
lug adapter plate that mounts to the appropriate load side busbars at the top of the bay (except bullet nose-
type devices which use the existing busbars provided at the top of the bay and do not require a lug adapter
plate). Load return leads are terminated either inside the bay if equipped with the optional internal ground
busbar, or outside the bay if equipped with the optional external ground busbar mounted on top of the bay
(see Optional Power/Distribution Bay Internal Ground Busbar Kits and Power/Distribution and Power Only
Bays External Busbars in this section).
