I don't do this full time so I am rusty on a lot of stuff.
A friend of mine asked me if I knew any reason not to use MC in an existing school for some new branch circuits. He does a lot of residential and says he is used to piping most commercial. I looked over NEC 2011 article 330 and didn't see any mention of building occupancy. Then I thought maybe a building code might limit its use but not sure where to look. I don't keep anything but Life Safety 101 on my shelf.
Sort of like I remember an article that allowed NM cable in a commercial building if it was not over 3 stories. An old boss of mine lost a bid years ago on an insurance company office building because he bid pipe and someone else bid romex. I don't remember where the rule is that allowed NM in commercial.
