The NEC snd NFPA sell books (codes and standards) and if you don't have the book covering the topic you are discussing, they will not have a conversation with you.

They will also not discuss specific detailed questions because, as an EE from LSU would know, they don't have a huge staff of experts. They use volunteer experts that meet on a regular basis to discuss recent accidents, new technologies, new products. I was on the NFPA expert team for a specific hazard and we'd get together every three years to discuss, and decide if an update/new edition is necessary. People would see my name in the NFPA book and, thanks to LinkedIn, they'd call me with half-baked explanations looking for me to tell local authorities or insurance underwriters that this or thst is safe. The only one who can make the decision is a paid PE who has been on site to see the action, or a local regulator, or an electrician familiar with the condition/industry/situation under discussion. There are dozens and dozens of NFPA Standards covering many topics, and specific situations, manufacturing processes. There is no way anyone should tell this half-story teller that he is ok to do anything. But, if they do, I'd like to see him tell his insurance company or a local regulator or investigator that some guy on AAC said it was ok.

The only half story teller is you. I have several NEC full books and read them for 40 years. Read Article 500 of the NEC and learn.

 

For a 120VAC running thru a metal plate must the 120VAC ground be bonded to the plate as a NEC requirement?

THE NOCO has no way of bonding electrical equipment or metal enclosures such as Trailers but supplies 120 VAC. A clear violation of the NEC intent and many will not know their Trailer is not bonded including many electricians thus requiring NOCO to perform providing a bonded connection. Deception at it's maximum with electrifying trailers and killing anyone who touches a trailer or the metal enclosure on it.

Service equipment
Bond all metal raceways and enclosures that contain (or support) service conductors [250.92]. Interestingly, the NEC requires raceways and enclosures that contain feeder or branch conductors to connect to the circuit “equipment grounding conductor” [250.86], which is actually a bonding conductor [Art. 100].

If a panel knockout is oversized, concentric, or eccentric, or uses reducing washers, bond around that opening. Use a bonding jumper, not a standard locknut (Fig. 1).

So, what are you looking for Ken, to educate the public, or a pat on the back
