Home Inspector question

Only if the hots come from different phases. In the NECH diagram, it appears they have 8 hots, 4 on each phase, and presumably the neutral is sized to 4 times the ampacity of the hots. So that is an MWBC. But you could use only hots from one phase, and size the neutral appropriately.

Same phase yes.

Okay, I should know the answer to this, but for the life of me, I cannot locate a reference in the NEC. If someone could point me in the right direction, I would appreciate it. On a recent home inspection report, the home inspector cited "mutiple conductors improperly connected under the same screw on the neutrel bar." I see this quite a bit on inspection reports, and usually I can just remove one of the conductors, and move it to an empty hole on the neautrel bar. However, there are no empty spaces available on this panel. It is a Cutler Hammer, BR series, and even though the house is over 10 years old, the electrical system looks good overall. I don't know who the electrician was who wired this house when it was built originally, but he obviously took pride in workmanship. This electrical system looks so good overall that I want to be sure that there is a code violation before I recommend a costly repair to the seller.

yea but 10 years ago you could still terminate 2 nuetrl wires under one screw...so whats wrong with the install..another unlicensed HI doing electrical work..

Actually, the panel label probably stated the neutral bar was only rated for 1 neutral.
As I recall, this section was added to the NEC because most guys weren't reading the label, and landing 2 neutrals, or neutral/EGC under 1 screw.

Oh I agree with that assessment..I have never been big on terminating 2 neutrals on a lug..aI will add bars to my panel to achieve enough termination room..but I think it is an injustice to us as electricians that the panel manufacturer do not equip a panel with enough termination points..
