Had an inspector "remind" me that starting 2011, "even though your neutral and ground buses are bonded in the main panel, the grounds and neutrals should not be on the same bus".
First of all, is he referring to a new Code specific, and what is it?
Second, what would be the rationale behind that if electrically these are the same?
I can see correcting the use of the same lug for a neutral and ground conductor which has been a no-no since I've entered this profession, but think of all the main panel designs that have one large bus for all neutrals and grounds. Does this now mean (if valid) that you need to install a separate ground bus in a new panel and bond it to the neutral?
Is there some other new Code reference that this inspector may be confusing?
Input please. Thanks!
