Raceway is defined in the NEC, Sleeve is not.

The definition of Raceway clearly states that EMT is a raceway and protection on the ends is required.

What is the actual argument at this point in the thread drift.

I agree that in this post emt needs protection. But your statement that all raceways need protection at the ends is not accurate if, by protection, you mean bushings.

EMT is a raceway, when used as one.

When it's not used as a raceway it is not a raceway. A sleeve is not a raceway.
 
OK better clarification. Now.

Under what circumstance(s) would a raceway not be required to protect the wires/cable that emerge?

I can run 1/2 emt with #12 wire in it and not use a bushing. I hope so cause I see it everywhere. Box to box install , of course.

Edit to add last sentence

speaking from experience....emt will not stop a nailgun. a 16 penny nail will go in one side and out the other in 3/4" conduit.

Yes it will and now think what we have should that nail bite into only the hot wire and its not bonded !!!!!!!!!!!!
Didnt protect anything and just increased the danger.Also note them self tap drywall screws go in it easy with screw gun.

Well a sleeve would not require protection at the ends except for 300.15(C)

300.15(C)Protection. A box or conduit body shall not be required where cables enter or exit from conduit or tubing that is used to provide cable support or protection against physical damage. A fitting shall be provided on the end(s) of the conduit or tubing to protect the cable from abrasion.

If the sleeve was in fact a 'raceway' the above section would be redundant.

I think a specific prohibition on the use of EMT for a specific use trumps just about anything.
You can't make the code apply where is does not apply Mr Trump.:smile:

[edit: for example, suppose I want to use emt pipe like that in a generating plant? The NEC has no bearing...no trump card allowed.]

So, you're saying that when I use a length of 1" EMT for my closet rod, I've got an installation that my AHJ can and will gig me for by citing 358.12(5) if I hang an electric tie carousel from the rod?

It's use is as a closet rod, not as a wiring method. The closet rod is outside of the NEC.
 
Al, I am with you. As for the closet rod, 90.2 Scope says where the NEC applies, and it only applies to the installation of conductors, raceways, and equipment.

However, an overzealous inspector and an exact reading of 90.2 and Article 358 may very well place your proposed installation into the nether regions of a code violation if that EMT closet rod is supporting electrical equipment. Same thing with using EMT (which does not contain wires) to support fixtures.

Certainly it would be ridiculous to cite a violation of either of the above. But it could be done via AHJ interpretation and a misguided reading of the NEC.

actually, the generating plant is subject to the NEC in most cases. what is not subject to the NEC is the distribution and generating equipment. Building lighting and such are still subject to the NEC even in a generating plant.

What about the new lengths of EMT that one can purchase, they are 20 ft long?? ;) :D

I really like the longer lengths of EMT but the only problem is that I always end up cutting them in half to fit into my truck:D

I think the closest you'll find a code book to a generating plant is in the little blue house outside. Makes good toilet paper.

'fraid not. Read NEC 90.2(A)(4) and NEC 90.2(B)(5)c

90.2 Scope.
(A) Covered.
...
(4) Installations used by the electric utility, such as office
buildings, warehouses, garages, machine shops, and
recreational buildings, that are not an integral part of a
generating plant, substation, or control center.

(B) Not Covered.
...
(5) Installations under the exclusive control of an electric
utility where such installations
...
c. Are on property owned or leased by the electric
utility for the purpose of communications, metering,
generation, control, transformation, transmission, or
distribution of electric energy.
I don't see how either of these two paragraphs exempts anything other than the areas within a generating station that meet the narrow exceptions listed.

:confused: Just what areas do you think are left for the NEC to cover? I'm saying the entire generating plant installation that is under the control of the utility (including the plant's integral parts) are not within the scope of the NEC.:confused:

Just remember that the floating emt must be bonded. pvc may be a better option.
Short sections of metal raceway do not have to be bonded. If you use PVC it must be Sch 80 see 334.15(B)
