Leaving bare wires in wall for future use

[JoeNorm]

Is there a right way to do this? I'll give example: Can you coil(but not terminate) one end of a piece Romex in a J-box that contains power and leave the other end coiled bare behind a wall for future use(no box)?

edit: by bare wires what I actually mean are cables suitable to be in a wall(NM-B)

There is no requirement to remove abandoned line voltage cables.

If there were no box, how will you find it later?

I typically do exactly that for bathroom vanity lights on jobs by a certain repeat customer General Contractor who likes to swap out what is shown on blueprints provided to me with cheaper , shorter , vanity cabinets he finds at the big box stores. I'll cut in the box for the light later after the vanity and mirror are set in place. No inspector ever complained , or even asked me about the practice at all.

There is no rule that says you can't leave energized wires behind the wall, only splices are required to be in boxes.

So when doing wafer lights over islands I do this I use 1 wire coiled around in the likely areas and then when the island is installed I put in the lights. If the island shifts 2 inches because this or that I don't have to come back again to move things.

Really I am going to look that one up.
If that’s true I’ll mess with Inspetor

An inspector in Tippercanoe IN. named Bill will not allow that.

Their is something in Art 725 about removing or tagging for future use. un-used communications wiring above a drop cieling.

If I were in that town I would do one of two things -
1) Do it and make him give me a code reference that says I can't
2) Do it and make sure it is one of the first things he sees, and when he calls it a violation say, "Aw shucks Bill, are you sure? Ok, I'll fix it."

The advantage of option 2 is that I can commit at least a hundred other code violations and Bill will never look for them.

2017 NEC
300.12 Mechanical Continuity — Raceways and Cables.
Raceways, cable armors, and cable sheaths shall be continuous
between cabinets, boxes, fittings, or other enclosures or outlets.

I have placed into wall for close future use (waiting on owner to decide the fixture) but never having it energized, that would seem to create a hazard, and potential fault.
The above reference would mean a violation not having an enclosure at both ends. Neither of the 2 exceptions listed with the section would allow for such an installation as proposed to be done. Or even the ones I've done, but being unenergized the hazards would not be present.
