In my area we are, in addition whenever installing either a new meter/service disconnect or an ATS the bond must be seperated. If you touch it, you own it. And YES in agreement to @Little Bill statement regarding multiple taps under one screw on neutral/ground bar, it's a no go.
That happened to me once, at a job at a design agency. Work had to be done at night, and there were some circuits we weren't allowed to kill.In my classes, I wanted the students to understand the why behind the rule. When you open the neutral on a MWBC those parallel loads become in series. The $14 hair dryer will be fine at 80V, but that $300 TV will let the smoke out at 160V. This is one of my favorite graphics from Mike Holt. There is a similar rule for wiring receptacles on MWBC (IE pigtailing neutral)
One of our guys did that years ago, he was cleaning up a 277/480 volt lighting panel. The project manger called me to investigate why around 150 ballasts suddenly went out. After interviewing the foreman, I knew exactly what he done.You don't want to accidently disconnect the neutral on another circuit, if it is a multi-wire branch circuit.
Note it says to have electrician evaluate for repair and not must be repaired.Home Inspection report:
"Noted ground wire and neutral wire under same bonding screw. This is not proper. Recommend licensed electrician
evaluate for repair."
Your inspectors missed the day they taught panel grounding/bonding!I've checked with two neighboring city elec inspectors about this, they both said I need to separate neutrals and grounds but ok to leave 2 neutrals and under one screw. ( For Home Inspection jobs)
I used to put the N and G from same cable in the same terminal (at service panels), the logic being you probably would have the associated ungrounded conductor(s) off if you were loosening the neutral. Then came the NEC enforcement of one grounded conductor per terminal. After that I went with two EGC's per terminal and one grounded conductor per terminal. Usually the EGC's are associated with the two adjacent grounded conductors.Your inspectors missed the day they taught panel grounding/bonding!
It would make more sense to leave one EGC and one neutral under one screw than it would to have two neutrals under one screw. You could run into the same situation you would have taking the neutral off a MWBC if you had to remove one of the neutrals for some reason and the other neutral was part of a MWBC. Or you kill power to a regular circuit from loosening the screw, or cause arcing at the least.
