I'm working at a new company and today an apprentice pointed out to me that a conduit needs to be supported within 3 feet of a coupling! When I told him I never heard of this, he said "oh yeah it's one of the first things I learned".
I asked for a code reference and he looked up 358.30A and really couldn't find exact wording. The closest he came to was the "tubing termination". Well, as far as I can see, a coupling is a extension of the pipe, not a termination.
What say you Joe Tedesco?
