I have to admit I am still confused and can not get a straight answer on the code language requiring NM cable in non-dwellings to be within a 15 min rated concealment.
This appears to prohibit NM if installed without a wall or ceiling covering with a 15 minute fire rating.
Wouldn't this rule prohibit it also above a drop ceiling which has no fire rating to the assembly? Any thoughts?
