(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!
