Talked to inspector this morning. He said it didn't matter if I was going to use 15 amp breaker or not and that you can't mix #14 and #12 in a circuit......no code reference cited.
You were talking to him and he didn't give you a code reference? Did you ask him for a code reference or did you just say OK and hang up the phone?
Tell your customer that you'll have to charge them to follow a rule that doesn't exist. Give them the inspector's number and tell them if they can get a proper code reference from him you won't charge them for the additional work.
Just throwing ideas out, here.
