B bphgravity Senior Member Location Florida Feb 20, 2005 #4 Re: conductors of different size in same circuit Why not on a 20-ampere breaker? #10 is good for 20-ampere and so is #12? You are always permitted to use larger capacity conductors on smaller branch circuits.

We've got a double negative situation with no double negative! It is not a safety/code issue if the setup is protected by a 20 amp breaker, is what we are all trying to say.
