We were called in to help a customer that was in trouble with the State Fire Marshal. They have a Physical Therapy business and lease the space they are in. They are also affiliated with a local hospital. We have built all required fire walls and are complete with our portion of the work. The problem is there was Romex wire above a lay in ceiling. Our electrician has changed all the romex above the ceiling as directed by the inspector. The problem is where there is a transition between the junction box and the wall or top of studs. The electrician says that a small piece of romex can be visible between the wall and the junction box and the Fire Marshal says absolutely no romex can be visible. Who is right and where in the code can I find the answer? As is evident I am not an electrician.

thanks.

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!
There is a homework forum hosted by engineering.com:
 
It doesn't matter for something like that. Trying to argue over it will ultimately take far longer than correcting the inspector's complaint, be it reasonable or not.

I don't intend to argue with him. The electrician is doing what he wants done. This is just curiosity because the electrical code is like greek to me. I can understand the IBC and the variations of it the different states use but I have trouble finding what I need in the electrical code. If you could tell me were it deals with Romex in a commercial building or above a lay-in ceiling that would help.

thanks.
 
334.12(A)(2) says this: "(2) Exposed in dropped or suspended ceilings in other than
one- and two-family and multifamily dwellings."
If you can see it, it is exposed. If you set the junction box tight on top of the wall top plate, there will be no NM visible.
 
Thanks resqcapt19 that is what I was looking for. It answers my question perfectly.
