There would need to be an exception in the code for that and there isn't any. No good, sorry unless it's a residence

Sure if it is a dwelling unit or you happen to live in MA.

But no if it is a non-dwelling unit outside of MA.

Wouldn't 334.12 (2) deny you using romex above a dropped ceiling in a non-dwelling unit no matter what state you are in, since an AHJ can only go stricter than the code but can't go more lax than the code?

It would if MA did not amend that section.

In MA we have about 60 to 70 changes to the NEC, in RI and CT they also have amendments to the NEC.

It is called the "National" electric code but that is really wishful thinking, many areas make changes to the NEC when they adopt it. Chicago and and I think NYC both have their own electric codes.

Los Angeles used to, til the state told them to knock it off. Then they amended the NEC with over 400 changes, until the state told them to knock it off. I think they are down to 40 changes now.

I was always told that the NEC is a minimum standard and that some AHJ's can adopt stricter standards but not looser standards. So is it possible for an AHJ to make an amendment let's say to the rule of 4 and a half feet for supporting or securing romex and make the new rule for themselves to be every 6 feet support for romex?

Some states are still on the 2002 NEC while others use the IRC. Many states amend. NC amended the change made for nm in crawl spaces. I believe NJ does not require Arc Faults. and so on.
 
Any area can make any change they want to the their electrical codes. The NFPA is a private non government organization and can not force any area to follow it.

That said it is a copyrighted work so areas don't actually change the words in the NEC, they write amendments outside the NEC.

The NECs I buy locally have the MA amendments in front of the official NEC so first I have to look up a rule in the NEC then I have to check the MA amendments for any changes to that section.

Now on the other hand OSHA rules are exactly what you describe, an area can require more then OSHA but not less.

I know about not all states adopting the new code and that it takes a few years before a lot of them do but I thought that the NEC (whichever year they are on) was a minimum and that they are not to go looser than that. I recently learned that some states don't have any code such as PA, so therefore I guess all bets are off in states such as those correct?

Any state can change the NEC to see fit. As an example, in CT, i'm not required to supply AFCI to smoke detectors in bedrooms, even though its an outlet.
 
Irc ?

Irc ?
