No, because of their physical size and the National Electrical Code (NEC) requirements for wire bending space, some restrictions apply regarding where these branch circuit breakers and sub-feed lug kit can be mounted in the load center. Please refer to the Installation Bulletin supplied with the branch circuit breaker or sub-feed lug kit for clarification of the restrictions.
NOTE: These breakers can be applied only in Square D SINGLE PHASE QO load centers. DO NOT USE IN Square D THREE PHASE QO load centers or other manufacturers load centers or panelboards. See the Instruction Sheet provided with the circuit breaker or sub-feed lug kit for further mounting restrictions that may apply regarding mounting these devices or adjacent branch circuit breakers.
