Clue me in guys:
Quote from above:
"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."
Are we saying above that the ceilings must be 15 min. fire rated: and the "floors have to be 15 min fire rated also??
Or to put it another way:
OPen joist ceilings, or attic floors CANNOT have NMC wiring???
1/2" sheetrock is at least a 15 min fire rating. 2 layers of 5/8" make a 1 hour wall I believe. Tommorow, I have to ask the Building Inspector, and the Electric Sub-Code Official (Head Inspector) for clarifications.
