Product Overview

SquareD QO312L125GRB Load Center Outdoor 3PH 125A 240D/120VD/208Y VAC w/12 Spaces /Three Phase

Load centers are not supplied with breakers – order conduit hubs for outdoor load centers, and breakers, separately.

Square-D brand load centers are wired after the National Electric Code (NEC), NEC 690.64(B)(2) requirements. They can be used as AC load centers or subpanels. They are mostly using QO plug in breakers rated up to 50 VDC for use as 12V or 24V DC load centers. They can also be used to combine the AC output from multiple inverters feeding the grid. When used as DC load centers they should be protected by a high interrupt capacity fuse or circuit breaker between the load center and the battery. In case of battery bank connected through the load center we use one of the Class T or Class R fuses, or the DC breakers used in the OutBack and Xantrex DC power centers.
