Hey all, thanks again for the help with the multiwire circuit thing...
Another issue: as I was looking around inside the panel box, I noticed that on two different 15A circuits there are 16 ga wires (at most) going into the breakers. On one of them the wire is pigtailed to the 14 ga wire which then goes out of the box. On the other, the 16 ga wire is again pigtailed to a 14 ga branch wire, but also to another 16 ga wire which feeds a doorbell transformer mounted to the outside of the box (another 16 ga wire then comes out of the transformer and goes to the neutral bar). I want to replace the 16 ga wires coming out of the breakers with 14 ga to comply to the NEC; my question is can I keep the 16 ga wire which goes from the splice to the transformer? Am I correct in thinking that this wire only sees the amperage draw from the doorbell?
This setup really perplexes me as the box bears an inspection sticker dated just a couple days before I closed on the house, so I know it was passed in its current state. Is there something I'm not getting, or is this dangerous and should be corrected? I'm leaning heavily toward the latter, I just want some expert advice before I do anything...
