I have a house that was started by someone else and they were in the stages of rough in. My question is i see that 14-2 was used for wall outlet and some of the wall outlets are tied back to overhead lighting. I know that 14-2 must be on 15amp and that 12-2 must be on 20amp. But is this up to code or do I need to pull it out. I understand that most wall outlets are used with 12-2 and that overhead lighting can be 14-2 or 12-2. Any help would be great.
