Can QOB circuit breakers be installed in 300 A and 400 A QON load centers ?
Issue:
Will 300 A and 400 A QON load centers accept QOB branch breakers?
Product Line:
QO Load Center
Resolution:
No, only QO breakers will fit in branch positions.
EXCEPTION: For applications in 300 and 400 ampere QON load centers (NOT QONQ load centers), bolt on QOB branch circuit breakers are available for 150 ampere (two pole), as well as 110, 125, and 150 ampere (three pole). A bolt on connector kit, catalog number PK3CA, is required to use one of the QOB branch circuit breakers.
