Prohibited use of NM?


Recently we did some work at a hotel and one of the buildings (which is an addition but a separate building all together) was wired completely in NM. I also found some above a drop ceiling which I thought was prohibited too, but of course maybe not at that time It turns out this was built in about 1999, where as the original hotel was finished in 1989. The original building is mostly MC, but tons of pipe work too. Any ideas how this could have passed inspection, or if it was permitted back then?

I live in Vermont, and the state usually adapts the most recent NEC within 6 months. We also have just a few additional state amendments that only restrict some things, not allow. Of course that's not saying much.

I'm pretty sure it was the '99 code (maybe '02) that prohibited use in suspended ceilings.

I'll add that, the code cycle is determined when the permit is pulled, not necessarily when construction is finished.

The legality of NM would be determined by the type of construction. It is not true that NM is not legal in commercial buildings.

08' code art. 334.10 & 334.12 or city criteria or authority having jurisdiction.

Even so, still not allowed above a drop ceiling. But I have no idea when this actually became code.
