Doing a job wiring a finished basement in another city that I haven't wired in b4 so I called the inspector to see about the use of 14 gauge romex ( The neighboring city strictly forbids 14. Some kind of local ordinance) The inspector calls me back and says I can use 14 on the switch legs but not on the home runs and I can still use a 20 amp breaker! In my local home area, if you use any 14 in a circuit it must be on a 15 amp breaker. I had planned to wire the entire thing out of 14 but I am glad I called!
