I have a NQOD 400A 3 Phase panelboard and I need a 100A 3 phase subfeed breaker. Im having trouble figuring out what type of breaker will work. Anyone have an idea of the correct breaker for this? Thanks

Any QO (plug-on) or QOB (bolt-on) breaker, such as a QO3100 can work as a branch breaker in this panel. You just need to choose the correct AIC rating.

This family of panel boards had an optional Q frame 'subfeed' breaker which were separately mounted from the bus bars, but they were usually only used for breakers 150A and larger.
