Out of all the thousands, if not millions of miles of wires I've pulled and terminated, do you know how many I've checked the type of wire after pulling it?

I don't check what I have pulled after pulling it either. But have many times come into an existing installation and had to make decisions on how to add something new, and knowing what is already in place comes into consideration many times.

If you were an inspector, with no markings you won't know for certain what was pulled unless maybe you were there when they pulled it.

Maybe go back and read the OP, it is not about removing all the sheath, its about removing part of the sheath that is in the raceway.

I will admit that may change things in some applications. I do not believe that removing all the sheath and pulling the conductors as if they were genuine THHN/THWN is what NEC intends though. I would seldom strip sheath inside the raceway or sleeve either, it would be stripped once inside the enclosure, and I believe that is the rule for sleeves used for added physical protection.

Hold on, the argument was the sheath has to remain because the identification has to remain.

You cannot see the labeling inside a box in either direct cable entery or cable entry via a conduit.

The minimum required is 1/4", right?

The believers leave 2 feet so the labeling can be seen inside the box. :happyno::lol:
 
I'd like to smack whoever removes the sheath before the cable enters the enclosure (like in the conduit used as a chase). I hate trying to match up a bunch of conductors coming out of a conduit. It is so much easier to see that this black and this white go into the same cable jacket when the jacket is in the enclosure.

I have both. But sometimes I need to sleeve NM cable for whatever reason. For instance, outlets on a basement wall, or a feed to a furnace or boiler.

A sleeve is understandable, when they pull NM or more often I find UF pulled in "complete" underground raceways, I have to ask why? THHN/THWN cost less, pulls easier, and can get it into a smaller raceway then UF or NM cable.

Funny you should mention boilers, that was the exact picture I had in my head. I go on too many calls where there is a boiler, a control box, zone motors and a bunch of flex with romex pulled in it going to all the components.

iwire said:
Dave, you are often in favor of commonsense.

Where is the commonsense in adding a splice and associated parts?

I'm not a purist, so if it makes sense, sure sleeve that romex, but some of the ways I see it done, like I described above makes me think that too many guys don't have any other kind of wire on the truck.

No one in this thread except you has been talking about doing that.

Does it cost less than the labor to set up two types of wire, supply junction boxes, mount them etc. in many cases yes.

I guess I was unclear, I was trying to say that yes it is okay to strip the sheath, I was of the idea that you agreed.

Why would code tell us to leave a 1/4" of sheath if it was not implied that we were going to strip the rest.

Nm cable can only have the sheath removed in the J box. With out the sheath it would not have any markings, therefore a code violation. The conduit is acutely EMT installed on the side of the house in Wrightwood. Snow area

If this fitting was used for the transition and the sheath was stripped at the fitting the same as if entering an enclosure you would never receive a violation notice around here

That is actually a violation since the wire within nm is not marked. The nm cable should extend to the panel or a jb. The rules for nm being sleeved in a panel is under 312.5(C)

No problem, just save a little bit of the jacket to slide over the conductors where they enter the enclosure. As an identifying label, not to make it look like the jacket is continuous from the point of changeover. If you feel this would still be a violation, what section would you cite?

The section I stated above

(e) The cable sheath is continuous through the raceway
and extends into the enclosure beyond the fitting not
less than 6 mm (1⁄4 in.).

312.5(C) Exception is one way to comply with 312.5(C), which states "Cables. Where cable is used, each cable shall be secured to the cabinet, cutout box, or meter socket enclosure." But there are other ways:

If the NM to raceway transition is going to a junction box, rather than a "cabinet, cutout box, or meter socket enclosure," 312.5(C) doesn't apply.

I'm not clear on whether the conductors in NM less their sheath are still a cable, the term is not defined in Article 100. If it's no longer a cable, 312.5(C) wouldn't apply.

If they are still a cable, then I agree, 312.5(C) would require finding a way to put a clamp on the raceway entrance to the "cabinet, cutout box, or meter socket enclosure."

The 1/4" of sheath serves no purpose for identification.
