I posted this at the M.H. forum also.

Talking to another electrician today who works in another area.

He tells me there is an inspector in this area, who says, when using NM in a commercial building, the NM in attics and basements must be enclosed on both sides, within 15 minute finish rating in living area and attic or basement area.

He said the inspector is using (twisting in my oppinion) the wording of 334.10(3).

I proceeded to tell him I was glad we do zilch in NM work and don't work in this area.

After thinking about it,I thought I would see what oppinions would come up here.
