Distribution Device and Load Lug Locations – Distribution Only Bays
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, 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 as shown in the following illustration, without
skipping any distribution device mounting positions within each half. This allows automatic monitoring of each
position and allows the controller to locate all distribution 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 customer provided return busbars. See following illustration.
