Ive always been taught that EMT should be strapped within 3 feet of a coupling. after a friendly disagreement today with a co-worker and actually reading 358.30(a) I see where I may stand correrected. Do ya'll think that a coupling would be defined as a "tubing termination" as described in this particular paragraph?

Thanks for your help,
Pig
 
emt shall be securly fastened in place at least every 3 m (10 ft). if they intended to have a fastener within 3 ft of a coupling wouldnt that make the minimum every 1 m?
 
From '65 to '90, the wording of the NEC required a strap within 3' of a 'fitting'. 'Fitting' was replaced with 'tubing termination' in the '93.

Yes - To your question.

I don't follow you where you say you stand corrected by your co-worker. 358.30(A) says 3' between termination points which a coupler is.

You were/are correct in saying that it is 3' within a coupling.

What length did your co-worker say it was?

No, he is not correct in saying that.

I stand corrected once again.:grin:

I interpreted 348.13 incorrectly. I don't have access to all the pretty pictures that most of you have. Would love to have access to them if they are free or readily available.

Haven't done much commercial until recently.

This may bring up the "handbook isn't code" arguement but I dug out my '93 handbook and the commentary for 348-12 (348 was the EMT article in '93) says:

"This section has been revised for the 1993 Code so that it no longer requires fastening within 3 feet of every coupling"

Because couplings are fittings, they required support within 3' on each side until the '93.

Right, I was trying to add on to your comment. Not contradict it. I should have explained myself more clearly.

Are you saying you never agreed with me?:-? Or just on this topic?:-?

Well we do seem to disagree with the differences on a panel board and the panel board enclosure and what is and is not allowed in the enclosure.

Yes I do agree with you when you say.

You'll never know! Maybe we'll all come into agreement one of these days.

This goes along with the myth that conduit had to be supported within 3' of a 90.Maybe some specs on jobs had called out for it, but it is'nt code.
