My employee says a 2 pole breaker is required by NEC for a multiwire circuit. I always used to just make sure the two hot wires from a 12-3 cable are on opposite phases as to not possibly overload the shared neutral. (which a 2 pole breaker does insure). He says it is safer when working on one of the circuits in that, turning off one circuit ensures the other one is turned off too. NEC ?
