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.

Certain receptacle circuits must be 20A, such as kitchen, DR, bathroom, laundry, but not all.
What you have is typical for an average house.

If you have a 14 gauge cable going somewhere that you need a 12 gauge cable, you could leave the 14 gauge cable there for some other usage.

Hint: The 20 amp bathroom circuit may serve only the bathroom* so you might as well run a cable nonstop from the panel up to there. Similarly a receptacle in the laundry area needs its own 20 amp circuit.

Better not to mix 12 and 14 gauge wiring on the same circuit; the breaker is limited to 15 amps here.

* One 20 amp circuit for lights, fan, receptacles all in one bathroom only, or for receptacles only in one or more bathrooms.

I always use 12-2 on lighting because if you install a ceiling fan it gives you the option of using a 20 amp breaker.
Why not just use a 20A breaker from the start???


If you use 14-2 on a ceiling fan and I may be mistaken but I believe some of the fans are rated for a 20 amp breaker.
Never in my life have I seen this with a residential fan. Ceiling fans draw less than most light fixtures.


If you use 14-2 on plug ends I believe the formula calls for 8 plug ends per breaker assuming all major appliances are on there own circuit. I always run 12-2 for appliances. If 12-2 it calls for up to 10 for normal household use. Not constant load.
NONE of this is correct (unless you are in Canada), even then I don't think it is right.


Instead of "I think..." and "I believe...", why not get your facts straight before replying?
