Can a QBL, 10k AIC rated main breaker, be installed in a QO, 3phase Convertible Main Breaker load center, to replace the factory installed QDL, 25k AIC rated main breaker?
Issue:
Product Design Features

Product Line:
QO Three Phase Load Centers

Environment:
Main Breaker

Cause:
Application

Resolution:
The QBL main breaker will physically mount in the load centers, BUT it is not listed on the short circuit current rating table that is supplied in the load centers. Because the QBL is not listed, the installation could violate the NEC, so this is not recommended or warranted.
