Can anyone show me anyplace in the code where it says we can ignore A if we meet B ????
Sorry, Jim, but I've got to repeat my post #105 here:
Charlie:
Then why does B repeat the part about about securing the conduit within 3' of the termination points? That's already covered in A.
I think that the last three words of B - "shall be permitted" - are exactly the words in B that undo part of A.

I think the phrase "shall be permitted" does exactly that.
BTW, Jim, I don't think anyone ever said an installation like this would look good, or would be accepted by the owner, or by the foreman, or anyone other than the code official. I agree, leaving the conduit unsecured would be crappy work, but I think it is allowed per the NEC.
For an example thats maybe a little more grey, say the trusses are spaced every 6'. Someone might be tempted to secure the conduit at every other truss - 12' on centers. I think that would be code compliant, and fairly well done work. However, it sounds like you wouldn't allow this at all per A.
