Hi All, I don’t have a copy of the 2011 code that Will County I’ll. Is still using, can I fish 8/3 NM B above a finished drywall ceiling and then down a concrete wall to a receptacle,cable would be supported here either in conduit or running board.
Thanks
Geo
 
I don't know your area but nm is allowed to be sleeved on the surface or a wall. I would recommend using conduit not a running board
 
It depends on the interpretation of subject to physical damage. Running it vertically down a running board has been a standard practice for years around here.

I was going for looks and ease. IMO, it is easier to sleeve in pvc then to find a 2x4 and nail to that. I personally think the sleeve looks better.

I agree, but I have heard some say that you cannot use a piece of wood and nail the cable to it. We do that with panels all of the time without a problem.

Why? I cannot of a code section that would make a difference here.

If you thinking of ceilings, OP said drywall.

He said exposed stapled on a running board

Ah, thanks. I was not thinking.

Even if the building has NM inside walls, exposed could be another matter depending.
