I've heard of several contractors that run 12/3 from the panel to the farthest room from the panel and split the circuit,red for one circuit and black for another.I understand that you wouldn't want these on the same phase but where my problem begins is now they have added a room addition on to the house and a DIY just attached to an existing circuit and now is overloaded.Actually it's not my problem but now the homeowners are upset about paying this DIY for all these problems,and he won't return there calls......imagine that!
