Is EMT required to be supported or secured within 3' of a coupling?
(A) Securely Fastened. EMT shall be securely fastened in place at least every 3 m (10 ft). In addition, each EMT run between termination points shall be securely fastened within 900 mm (3 ft) of each outlet box, junction box, device box, cabinet, conduit body, or other tubing termination.Please settle a bet.

A coupling would be a tubing termination would it not

A coupling is not a termination but an E type conduit body would be.
I can see your point, heck I have even argued that point.
But then someone pointed out they had removed the word 'fitting' and replaced it with 'termination' so that you would not need a support withing 3' of a coupling.
It becomes, at least to me, a question of NEC minimums vs good solid design. I prefer to place supports near couplings but no longer believe it is NEC required.
No, not now, and maybe never the intent but the wording used to require it.
I cannot remember what code cycle it was when the wording was changed from 'fitting' to 'termination'.
If you start with a 10' stick, secure at or less than 3', then continue with full sticks until the last piece, and support at 10' intervals, the supports will always be within 3' of a coupling.

Actually a freebie.... construction crew left it behind.Good thing you bought that used supercomputer to run those calculations.

Well, when I said support every 10', it meant measured by the conduit run pathway.What happens when you put a saddle in that 10? stick?
