Can a QOB breaker be used in a QO load center?

Issue:
Product Design Features

Product Line:
QO load centers

Resolution:
All QO Load centers are ONLY designed to accept QO plug-on type branch breakers. So a bolt-on type branch breaker CANNOT be installed into the QO load centers.

NOTE: For a back-fed application in a QO load center, a plug-on type branch breaker must be used. Also, the correct retaining kit part number MUST be used for compliance with the National Electrical Code (NEC).
