Acceptable routing
 
I need to run a line from the attic down to the kitchen for a dishwasher. Our top cabinets have mouldings which go to the ceiling and the mouldings are not on yet. Rather than trying to drill a hole through the header which is very difficult to access, then go directly down behind the wall, can I drill a hole in the ceiling above the cabinet, where the moulding will be later covering entirely, then into the wall and down? I was planning on using MC 12/2 with separate green ground wire.

yes. 12-2 W/ground will be ok.(all 3 wires in same sheathing) Just curious as to why your coming from the attic?? :thumbup:

My concern was the routing... going through the ceiling, then through wall as opposed to through the header in which case it would all be behind the wall.

The basement is finished unfortunately and I believe I would have make many holes in the ceiling to come from below. Have to go from one end of the basement to the other and the joists run perpendicular.

I don't think what you want to do violates any codes. But then I don't have them all memorized either lol. Way I see it once you put up the molding you wont even see the cable. Are you using 12-2 w/ground?. Will be 3 wires blk,wht,and green all in same sheathing. I know you mentioned a separate gnd wire. Did not know if that meant you were running a ground by itself. as opposed to it being in the sheathing with the 12-2

Just my 2 cents :thumbup:

Code does not permit you to run a separate ground wire outside the MC. Some MC sheath is listed and approved as the equipment ground. Check yours. The path you wish to take with it is no problem.

It's MC with 3 including green ground within the armor. Sorry for the confusing description. What I meant by separate was that it had a ground wire as opposed to the sheathing being the ground. Thanks.

Ok, then you have no problem with your plan.
