Larry:
I was tempted to advise against this. I see a similar concept with people
trying to parallel PV feeds and then putting two charge controllers at the
destination. Not good.
However, I see many 200 amp main breakers that are 4 100 amp breakers
ganged, with two for each phase. I can not presume to know about the
requirements of internal ganging.
