1 Connected to DRd enclosure with a full complement of 20 A modules.

Connected to two DRd enclosures with a full complement of 20 A modules.

Installed in a main circuit breaker model auxiliary enclosure.

Wire bending space limits the feed to the AX12X-MCB to 400 A maximum.  ETC installs a 100% rated two pole breaker (or two poles form a three pole breaker) in the AX12X-MCB, for a total deliverable current of 400 A in a single phase (split phase) configuration.
