I really do not get you guys. Is it just the contrarian view?
Under your suggestions, it seems we could hook up the AC, the baseboard heat, and the microwave all on one breaker because the breaker will take care of it in case someone turns them all on at once.
So the NEC allows a double pole 20 amp breaker [simply two singles ganged togther] to be wired with 2 wires or circuilts on one half of it that is sure to be loaded to 40 amps at some indeterminate time?Second one can’t overload half of a two pole breaker. The breaker is either overloaded or it isn’t.
I am sure any electrician, including the building inspector, will insist that the 2 permanently installed appliance be on seperate, independant circuits.
