I have 7 outlets on one circuit. It has a 15amp breaker and is wired from one to the other in 14/2 My question is, I have a small(6' section) where I have to change around, and I will need about 6' of wire to connect this outlet. Question is I have a whole bunch of 12/2 romex and want to know if i can use the 12/2 for this 6' section. It is still just outlets in a series. Thanks
