I'm finishing about 2/3 of my basement with the remaining 1/3 being a dedicated storage area. The perimeter of the finished area is about 180 feet and I'm planning on having about 20 recepticals. I will only be using a fraction of the recepticals at any given time but I just want to make sure I always have one in the spot I need it, so I'm throwing in extra ones.
I plan on using 12-2 copper wire with a 20A breaker & 20A rated outlets. At first I was considering using 14-2 with a 15A breaker but I'm concerned about voltage drop over my relatively long 180foot run. The extra cost and hassle of installing the 12-2 is something I don't have any issues with so I decided to go that route. I'll be routing the 12-2 through traditional wood frame 2x4 walls I have setup against my poured concrete basement walls. I have already drilled 3/4 inch holes in the studs.
I'm installing the outlets so that they are 18inches above the basement floor and spaced less that 12feet apart (no more than 6feet from a doorway). The routing of the wiring through the wall is at least 12inches above the outlets.
Any feedback on my plan? Anything I should look out for or consider? Anything I should watch out for using 12-2 with a 20A breaker?
