(One more) Dedicate power line: twist questions, oxygen-free, and code questions.


I wonder if I might ask the following question of this community, as I’m also contemplating running a dedicated line:

I’m contemplating purchasing several runs of single-wire, solid core, 10AWG, for black, white, and green. And then making my own cable. I’m thinking of doing TWO 10AWG runs for each color: first twisting these like colors together: black, white, then likewise two runs of green, then putting each into a fiber mesh before then braiding it all together -- much along the lines of what I’ve seen in high-end power cables. And, separately, I wonder if the above setup would pass code.

I’m also evaluating 99.9 and 99.99% oxygen-free copper, though I don’t know just how important or beneficial this may be. The additional cost of this would be relatively insignificant compared to the bear of a job to run the lines in the first place -- so, once up there (boring multiple holes in the ceiling for access), I want to do the job right.

I had planned on bringing this one (paired-up) set of wires to a box with two outlets, wiring it to one outlet, then jumping it to the other. With the advice to keep digital and analog separate, might I be better served to keep this configuration, but split the feed at the panel end into two breakers, and then split the feed at the outlet end into separate one each -- and still using that one big braid along the way? Or might jumping the two outlets be equal enough?

I would appreciate anyone’s thoughts on either the code issue, the twist strategy, the separation of the lines, or the oxygen-free issue. Thanks in advance!

As far as keeping analog and digital separate, my understanding is 2 separate outlets, each having it's own separate run back to the panel box on separate breakers. Key word is separate. Jumping one outlet to another or braiding is not separate. As far as wire, I experienced a friend going through many different ones trying to find the best for his dedicated lines. He finally settled on the cry'od Romex from VH Audio (no affiliation), and it definitely sounded the best.
