EMT - is a wall considered securely fastened

[Gategator37]

If I have a conduit passing through a 2x4 steel stud wall, is this wall considered a support for my EMT? I believe that I am supported, but according to the code it states I shall be SECURELY fastened. Does this mean I, at a minimum, need a strap at this wall?

Its clearly supported. i am not sure it is secured, but a zip tie would secure it IMO.

As any, the topic is debatable:

IMO there is nothing to debate about when we are talking about a 'stud wall'

You must be secured within 3' of the box and only supported every 10' there after.

The debate comes when we move out of stud walls and into other types of 'framing members'

I agree. Those threads came to mind but aren't exactly what he asked. Although, after reading, they cover "securing" and "supporting" very clearly.

If the conduit is going thru the studs then, IMO, it is supported. No different then MC cable running thru the studs.

Sorry fellas let me rephrase. The conduit is running perpendicular through a corridor then through a wall in to a classroom. So nowhere is it actually running parallel to a wall it is running through a wall... perpendicular.

In that case I would have to say it would be up to the AHJ.

Well the wall is only 4" thick so how close are the supports on each side of this wall or corridor?

IOW's, how close are the supports on the length of conduit?

So, the question really is whether the conduit in the hole through the drywall is considered secured. If the hole is snug, it's certainly secured in two directions. Does it move freely through the hole?

Personally, I'd consider a conduit passing through a snug hole in the drywall as support. As mentioned above, the wall can be ignored as long as the usual fastening is used on each side used.

Now, if this is a box on the corridor wall, and this conduit is poking out of the back of the box and through the room-side of the wall, I'd say you still need a near-the-box fastener. Sorry.
