I have an outlet box (a simple receptacle box, not a cabinet, cutout box, or meter socket box, so I don't see 312.5 applying to this) surface mounted on the block wall of my garage. Then I have NM cable in EMT (for physical protection) leaving the box going up the block wall. I have a drywall ceiling in the garage. I want to go through the dry wall ceiling and go on my merry way with just the NM cable. My question is: How do I go through the drywall ceiling? Do I have to stop the EMT short of the ceiling and go through the ceiling with the just the cable? (Of course, I'll seal around the cable) Or, do I go through the drywall ceiling with the EMT and then exit the EMT in the attic? (The attic is unfinished, no floor or anything.)

Best Answer
Go ahead and have the EMT penetrate the ceiling, then use an EMT-to-NM transition fitting in the attic where the EMT ends:
