I think it means what you think it means but it does not seem to say what we think it should. :grin:
Also it is not on top of the framing member it is running through it.
I'm invoking Charlie's Rule on you!
Suppose the EMT is run below the framing?

OUCH! Red tagged from left field.
We get on some jobs that follow that for everything but on most of our jobs 1/2" through 1.25" are routinely supported by the bottom cord.

Hey you know use "two mood" inspectors.:grin:
I didn't say you couldn't, but you may not be able to. Had one where the structural engineer said that they could only hang off of the top chord.

And the OP did not use the word "series" in that context either.
So it says what it says.
Geez, I know times are tough, but would you really want to do an install like that ? I guess running a conduit in the "V" of a bar joist is going to give it more support from lateral movement, but by the way most are reading the code section you could just put the conduit on the wide open flat section. Leaving the conduit with no side to side support, or support from uplift. It wouldn't pass here. No different then just laying it across the flat roof of a building.

I agree with you. Looking more closely at the wording.
- Securely fastened in place AND supported . . . .
- . . . in accordance with 358.30(A) AND (B).
I vote no.

I hope it is at least a quality burritto from a good Mexican restaurant, and not one off a taco truck that stops at the jobsite.

The EMT is only required to be 'securely fastened' within 3' of box or conduit body, beyond that it only has to be supported when run through framing members. You cannot try to use A and B simultaneously.
I agree and voted no to compliant as well.
I don't agree..anytime the Code says "AND" it means both (or all) conditions stated must be complied with. Unless you can show me a section without any "AND" conditions for this install that trumps what has already been referenced I stand by my answer. :grin:

This is the key to my disagreement with the majority, please elaborate.
As I see it, both "A" and "B" apply equally to the EMT, so therefore B's existence is fairly moot: as all conduits that are fastened will necessarily be supported in the process of fastening.
Attached is one from the 2005 handbook (kudos to those who pointed that out.)cowboyjwc said:

As I see it, the fact that if you try to apply "A" and "B" together it makes B entirely moot is proof that A & B are not to be used together.

Of course that is supposed to be true.
In this case I can't explain it other than IMPO it is an error. See my answer to George about why I feel it is an error.
My opinion remains the same, compliant.
The picture from the handbook references IMC, not EMT. So it is non-compliant. So far the minority is correct....:grin:

I'm with Charlie - the "and" needs to be an "or" for the text to make sense.

In the handbook, it refers you back from the EMT article. Nice try.
We agree on the first part.
Is it an error? Possibly. Code is not perfect, we all know that.
I still disagree with your opinion on compliant though. :grin:
And as I mentioned in my post above, the handbook calls out IMC, NOT EMT so I would still say no way is this compliant.
