I know a horizontal run through punched studs count as a support for EMT but does the horizontal penetration through drywall count as a support?
 
if the rock isn't already up, just ensure there's a framing member there with a hole in it -- screw up a length of stud horizontal and flat with a hole punched.

if it is up, do the same thing screwed into the studs :D

I think it supports.We often strap to drywall so why can't it support emt

Is drywall a framing member?

Yes i think it is.Does it not add strength to metal stud walls ?

I would say sheetrock adds STABILITY..not strength .

Jim, if it is a framing member why do we bother with the studs?

Perhaps for same reason we use screws.

If drywall can't support emt then i guess it can't support cut in boxes ,remodel cans,4 foot wraps,panels.You need to look at its strength in the direction of the load.Even a piece of papper can hold a lot on its edge.I am not suggesting 4 inch emt with 500 mcm but 1/2 or 3/4 could easily be supported.
 
That blue 5/8" firerock is a sturdier support than a 1-hole strap...you could do chinups on a piece of pipe coming through that stuff and not dent it at all :lol:

That's just plain wrong. I'd be lucky if I could do just one chinup. :p :p

:oops:

Good point Jim, I'm not sure I'd want to use drywall to support anything like a 100 or 200 amp panel, though. :)
 
There is a limit to what it can safely carry.House panels maybe but not much bigger.This is a common sense thing and what direction the pressure is makes a difference.

I disagree it is a 'code' thing. :lol:

The code does not allow EMT running through drywall to be supported by the 'hole'.

If you do so (and I have) and the inspector decides to enforce the code as written you will not have a leg to stand on regardless of how well the EMT may be supported by the 'hole'.
