Branch breakers


A Bolt-on type branch breaker CANNOT be installed into the QO load centers. The QO load centers are ONLY designed to accept QO Plug-On Type branch breakers. 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 PK3MB) MUST be used for compliance with the National Electrical Code (NEC).
