[QUOTE="Tim McCulloch, post: 130023, member: 67"] Re: Recent Talk with a Licensed commercial electrician has me thinking. Either you mis-heard, he mis-understood, or you should never, never, ever spend any time in a building he wired. Serious as a fucking heart attack... As other have pointed out, it's a violation of Code to install wiring smaller than #14 (on a 15 amp breaker) in a commercial occupancy, and that's for old "grandfathered" work. Current Code does not permit new branch circuit wiring smaller than #12, protected by a 20 amp breaker. Also as pointed out, voltage drop is cumulative; i.e. it's a function of the total circuit resistance. Your bigger wire means less resistance and less additional voltage drop. This is a good thing and is not a waste of time or money. [/QUOTE]
