QO load centersEnvironment:
QO Load centers, both single phase and three phase 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 (1-phase and 3-phase), 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).
