12-3 Double Circuit Run Length - Should I Split the Circuit?
Hello
I just finished wiring my basement with 12/3 wire. I was planning on using a double pole breaker with two circuits and a shared neutral (alternating circuits between outlets). My run is around the perimeter of my basement inside wood framing studs. After all was said and done with the requried routing, I've used about 250ft of wire. I'm concerned that I may have too long of a run and that, instead of creating one big 250ft run with alternating circuits on a double pole 20A breaker, I should just have two 125ft circuits on separate 20A breakers. I guess now's the time to make my decision before I go into my panel. I've already run the 12-3 wire but I don't mind using only 2 of the 3 wires if that will make these circuits better performing and safer. The reading I have done so far and the 13.6% voltage drop at 20A calculated using this website: http://www.powerstream.com/Wire_Size.htm has me leaning heavily toward two separate 125ft circuits. Any feedback is apprecaited. Thanks! Kevin |
