Main Battery Termination Bars (MBTB’s)
Plant is designed for centralized configuration with customer supplied Main Battery Termination Bars
(MBTB’s). Emerson Network Power Services has standard MBTB’S in 4000, 6000, 10000, and 16000
ampere capacities. The ultimate plant capacity is determined by the capacity of the MBTB’S. Refer to the
EA3434-41xx Series MBTB’s drawings.
Distribution Device and Load Lug Locations
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 located 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.
