Round orange NM cable with a black stripe?

I took my family to New York for a day trip, and saw one of those plywood makeshift (a.k.a. probably permanent) restaurant outdoor dining areas wired with some round cable with a black stripe. Ok, I figured, some hack job passing an extension cord for temporary outdoor wiring.
But then I see this cable again in an Electrician U video (look at 4:35) (
).
Did I miss a memo about a new cable type listed for exposed outdoor use?
 
Just got curious so I started watching the video. The gist is (his opinion, not what code says) is you can run lots thru one hole but capacitive Coupling is the real reason not bundling of conductors. I'm not going to agree to that , although I also think in residential it ( bundling) is an overblown concern that very very rarely becomes a problem. Then he states he doesn't like more than two because the abrasion to the sheath is more likely when multiple cables are pulled thru drilled holes. Me? I use yellow 77 on residential jobs. I pull wire without the tire. It makes it all so much easier albeit messy. Roll of paper towel and my exploding garbage bag nearby fixes that. So I don't worry about three cables in a 7/8" drilled hole. This doesn't have anything to do with the subject of the original poster, but hey , you added the video so I added the yellow 77 comment for those who haven't ever tried using it. It's great for NM cable just as much as it is for pulling thhn thru emt.

No, I have no idea about a round orange cable like that with the black line along the run. My 10-3 supplier doesn't' even make round 10-3 any longer they always have flat stuff now which is a pain in the drain by the way. Mikey out......

What bugs me about that video is, like practically all inspectors do, he left out the ....."without maintaining spacing" and "greater than 24 inches" parts

Still wondering why nobody makes a miniature plastic version of that thing you see on overhead power lines sometimes that holds the lines apart. Something like a solid circle with say 4-6 idents in the perimeter into which you could snap cables. Put one in every joist bay to spread your cables, and now you've maintained spacing, regardless of how many cables are in each joist hole.

In seattle, a few inspectors are picky about the bundling. Residential job I just finished I said the hell with it and pulled more than four cables through some holes and figured if they said anything I would just use the nail to the side of the joist cable stackers, snapping a few on and each Bay (but not securing them, just letting them float). Seems like that maintains spacing to me. I was not there for the recent rough-in inspection, GC said the inspector grumbled a little bit about it but didn't write it up as a correction.

I'd go with your gut. It looks like an extension cord to me.

it's just too much of a coincidence - first I see it in NY, and then I see it in Dustin's video, less than a day apart.
This is what made me think that there is a new type of NM cable out there that I haven't seen yet. My warehouse guys haven't seen it either.
What gave me a pause is that Justin is a master electrician, and he makes those mock-ups that you see in his studio - this is not a random job site.
I just can't see him pulling an extension cord through those 2x4s just to catch smartass comments from viewers.
 
The wire in the video is definitely not NM. The jacket is perfectly round (does not conform to the wires inside), it is fine stranded by the way it hangs between studs and what little I can read shows 14 AWG. Its either extension cord or CL2/CL3 low voltage cable. I'm guessing extension cord so is not permitted for in wall use even for low voltage.
 
In no particular order:

A. That IS rubber cord, not NM.

2. Heat IS the reason, not capacitance.

D. He doesn't know the difference between conductors and cables.

No, I was thinking of a miniature plastic version of the spacer shown in the picture below. You could put one in each joist bay to ensure that any bundling that occurs at a hole in the joist doesn't extend for 24". [Although that wouldn't work for NM cable through holes with insulation.]

But electrofelon already suggested just using a stacker floating in the joist bay for the same effect.

I agree something like one of those Hendrix spacers would be nice. Maybe more likely to appease the inspector if it's "intended for the use" (even though there is no requirement that it be).
 
The only problem I could imagine with this image is in my neck of the woods, Calif .. It was always a no no to run data parallel with higher voltages, crossing ( + x ) was ok, but not running ( = ) side by side or in the same stud penetration.

basically as many of you know there could be flux line disturbance to the data signal from the paralleled higher current conductor.
