[QUOTE="The_Quiet_One, post: 8486267, member: 614562"] 1) You seem to like quoting NEC a lot....What does NEC have to do with anything in this scenario? We are not trying to be in line with electrical codes?! Electrical codes do not say anything about what can or cannot be done. They just provide a guideline for best practices in professional applications (read as go to borderline extremes to reduce potential liability issues)[IMG]//content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif[/IMG] I'm not going to argue against the fact a bigger wire is better. That's pretty safe to assume for most of the time, but in this case it is not [B]required[/B].
