Tesla has used two conductors in parallel for each of the hot wires [4 conductors total + ground] in their UMC and WC cables. I don’t remember the AWG used. This allows the cable to be smaller and much more flexible than using single conductors like conventional extension cords do.
I did.Did you do a Conduit Percentage Fill Calculation?

Not only that, the wiring is able to be encapsulated in insulation, which makes it hard to dissipate heat.

Wouldn't it be more typical to use stranded here instead of romex? I'd expect that pull to be really hard, even with larger conduit.
If someone can do conduit the whole distance, then sure, you probably would, but I'm not sure where the rest of this installation went. If this was the section that had to be outside of a wall, but then the rest of it was going to go up through an insulated wall, then you would want to use Romex for that other part. So it was probably easier to use one type of cable for it, with some in wall and some in conduit, than to splice it in a junction box for those two different areas.
Couldn't you strip the jacket off of just the Romex section that is going-into the conduit?
You could physically strip off the outer jacket but the individual wires are not labeled, have no rating. My understanding is installing the individual (unlabeled) wires in conduit would not meet code.
You don’t technically need to swap the breaker. But it would be a little safer.This is an easy fix. Adjust your HPWC to 50 amp and swap out your breaker to 50 amp.
This will increase your Home/EV safety and get a huge Thumbs-Up from all your friends here at TMC.
12AWG is acceptable for a 20A circuit, but will generate more waste heat that will translate into a larger voltage drop on the wire; if the voltage drop is large enough (typically > 10V), the car will reduce its draw from 16A to 12A, eliminating the benefit of installing a 5-20 in the first place. If, your breaker box is in/near your garage and the wire run is, say, 50' or less, 12 *should* be fine, but personally I'd err on the side of caution and use 10AWG if you can.
This 6ft section was not solid wire. Nor was the old welding outlet I replaced. They were both similarly stranded wire.
I think the word "stranded" was just a mistaken use of a word. That's not what was meant. All of these thick wires are stranded inside, whether they are in the installation format of wire in conduit or Romex. They have to be to get any flexibility to work with them at all. Solid wires are only used in the thin ones, like up to about 12 gauge? I'm not sure if you can get solid 10 gauge or not, but once you are talking about 8 or 6 or larger, it's all stranded inside.
Phew, I was thinking about dealing with solid at that size and would need have hit the hand exercise grips for a few weeks prior
Johnny Vector . if you think 6/3 romex is not for 60 amp breaker then which size cable do you recommend ?
