Am I the only one who prefers to cut their electrical tape (usually with dikes) instead of ripping it? I'm a desk jockey, so maybe I'd do differently if I was an installer and had limited time, but I despise the wavy end of electrical tape that you get from ripping it....
Good video. I like the idea of wrapping the drain wire back over the jacket.
We preach the same song, grab that pull string and rip another 8"- 12" then cut off the excess and start working. Tape back the shield, folded at the end for removal. Two labels one near the end and another in the panel chase.

Most of them will apply labels to cable ends when the pull is done. Before they get down to dressing and terminating the ends. We have them make labels that make sense. Not numbers. Rather labels that read like, "AHU 1 DAT", "AHU 3 RACO2", "Rm 215 ZT", etc. We have a standard for what we call things, and it shows up on the schematics that the installer is following. For comm cables they're marked in a format like "From ..." and "To ...", with the rest being an identifier for the device concerned. Really not necessary to indicate its a comm cable since (1) label makes it obvious, and (2) the comm cable will be the only one of that color we'll use on a project. We have standards for colors for comm cables. Such and such a colored jacket for BacNet, different color for Lon, different color for Modbus, etc. Non-communications cables will all be white jackets. Helps keep things straight. i.e. I've worked projects where we have AAM's Pup, BacNet, Modbus, and LON all in one building.
Green sleeving over drain wire, white heatshrink over point where outer insulation finishes (and green sleeving begins) with cable label written on it. Wire numbered of course, even tho I HATE WIRE NUMBERS cos they're so time consuming. Interestingly I read that in Germany in the automation world they were moving away from them...
Bootlace crimps (which I used to hate but i'm changing my mind in CERTAIN circumstances) on any fine wire or flex, altho i ask the individual BMS guys if they do or don't allow them on any RTD wiring. HEXAGONAL (6 pass) crimper does a much better job too, worth the extra $10.00.
I don't think you should rely on tape anywhere it's important.
That said tho, I recently terminated a huge BMS control board, alot of 0-10v and comms etc, which all tested ok after fixing the usual odd mistake, then I realised I totally forgot to earth the shields. They were all connected together ready, but forgot the last wire to ground. And there were a couple hundred cables... Hmmmm
Also regarding HI VIS, I have a theory that if you get 3 or 4 guys in hi vis you could steal anything in the world in plain sight...
The DDC system... guilty until proven innocent
I cut my tape with a razor knife...... cut a lot of things with a knife......but Im very carefull and I always look to make sure I have not nicked or scored anything I shouldnt...
