Received a call from a ‘Master Electrician’ telling me my report incorrectly identified multiple neutral wires in a single lug as a deficiency…

That electrician needs some additional training. You are correct it was never permitted to have more than one neutral per bus hole. For the past 20 years there has been wording in the NEC to clarify that it has never been permitted.
408.41 Grounded Conductor Terminations.
Each grounded conductor shall terminate within the panelboard in an individual terminal that is not also used for another conductor.

The majority around here also could use additional training on this very subject, I find them daily.

I think it was one of those things that no one knew about. The wording added to the NEC should help but old habits are hard to break.

D’Arcy, next time ask him/her to put the opinion in writing, on their business letterhead, with their license number and email it to you.
That has quieted them for me…immediately.

As long as Journeymen continue to train their apprentices the incorrect methods, (because that is how they were trained long ago), the problems will perpetuate itself!

What do you expect, they still think the voltage is 110/220. I see this pass inspection on new builds, so it must be correct.

Remember that many of these AHJ Inspectors are the same as many Home Inspectors… Ex and Retired Trademen… so why should they be inspecting any different than how they constructed??
(Ya, I know what I said… and we all know there are always exceptions)!

You would think that inspectors would be required to take some sort of continuing education to keep them up with code changes. Here in NJ us licensed electrical inspectors are required to take 15 hours of CEU’s when we renew our licenses every three years. Electrical contractors are required to take 34 hours every three years so they should have no excuse for not being up on the code.

I always thought that a “bus” was something you drove and “buss” was what you found in an electrical panel. It appears that ChatGPT agrees that “bus” is acceptable: 
“Bus” and “buss” are two different words with distinct meanings:
-
Bus: This term refers to a large motor vehicle designed to transport passengers, typically along fixed routes. Buses are commonly used for public transportation, school transportation, and other forms of group travel.
-
Buss: This term can also be spelled as “bus” and is used in the context of electrical panels and systems. It refers to a metal bar or conductor used for distributing electrical power within a panel or a larger electrical system. The buss bars (or busbars) in an electrical panel help connect various circuits and components to the main source of power.
The word from the NEC is bus. Buss is incorrect.
