How to Add Sub-Feed Output Distribution Circuit Breakers to the ATS
InfraStruXure Power Generation System 69
Circuit breaker adapter modules available from APC
Adapter modules are required when mounting breakers onto the panel bus in the ATS. Each adapter
module can accommodate two breakers.
APC’s adapter modules are sized to fit all of the circuit breaker types described on the previous page:
T1 single-pole breakers, T1 three-pole breakers, and T3 three-pole breakers. Two types of T1 single-
pole adapters are offered: one that plugs into either L1 or L3, and one that plugs into L2. When
adding single-pole breakers, try to keep the loads balanced among L1, L2, and L3.
Determine the configuration of the panel
Before installing circuit breakers on the ATS panel bus, be sure enough space is available on the bus.
Use the information below and in the next section to determine configurations.
