I am running a new circuit to my attic for ceiling lights, and am (fortunately) able to get behind a kneewall to run the circuit where i need to go. The electric comes up into a crawl space (one side is insulation on a knee wall to a finished room, the other side is the roof slope). I've stapled the wire onto the knee wall studs up off the floor and now am in a tricky spot.
Before i can run the cable from the crawl space to the attic, i must go through a closet of sorts (due to the slope of the roof it is an awkard closet and would be tough to store much more than hanging clothes). i purchased some plastic conduit to protect the cable in this space, and was hoping to run it close to the wall to give some additional support (can't be pushed back) and is a little more out of the way.
in order to do so, it would look like i would need to stable the wire to a roof rafter. One side of the entry hatch to the crawlspace is *right* next to the roof rafter so there isn't much of an option if i want it up and out of the way. It would take about 3ft of cable and then would drop down to get into the closet.
i am in update new york. Does code allow me to do this? I understand not attaching it to the decking (nails when roof is replaced) but what about the underside or bottom edge of a roof rafter? I am able to get into the closet without doing this, but would feel more comfortable with it following the edge of the closet wall for reasons stated above).
If you are running Romex through the closet, you might as well just pull it between the sheetrock and roof. That way, you treat it as a retro run, no need to staple. Otherwise, you would have to transition the emt into the attic space, and seal both sides with firestop, or transition into a junction box in the unfinished side.
