Planning to install the wall charger soon and i'm planning on getting these (10' black and 10' red + 8gauge copper wire). Is it code to have those 3 wires inside a conduit which will be behind dry wall?
Thanks!
Thanks!

Well yes. You have to choose one or the other. It's not allowed to just put straight THHN or bare copper loose inside a wall. You have to either go with the NM-B cable, or you have to use conduit to put the individual wires in.Planning to install the wall charger soon and i'm planning on getting these (10' black and 10' red + 8gauge copper wire).

I think municipalities other than Chicago do not allow Romex wire runs as well. I know that NYC requires conduit.Well yes. You have to choose one or the other.

Freaking Chicago area is ridiculous. They just have a full-stop prohibition on using NM-B cable at all. Period. Absolutely everything must use full conduit everywhere, which is kind of dumb if you're just needing to put something straight down through a wall--that's what Romex is for.
- Yes. Of course.
- No. Don't do that.
- Use 6/2 MC, 4/2 NM, or AWG6 in conduit.
- Or just make it easy on yourself and go with regular old cheap 6/2 NM and a 40A charge rate limit.
You're making it confusing by not fully specifying what you're talking about.6awg is only rated up to 55a
You seem to be responding to the last item #4 in @Gauss Guzzler 's comment, when he then switches to suggesting 6 awg of the NM-B cable, known as Romex. Yes, that one does have the 55A limit, because it has to use the 60 degree C temperature rating. But's why he immediately specified only using that with a 40A charge limit on a 50A circuit, so it's still code compliant.AWG6 same issue with 55a limit
Describes my setup exactly. 6/3 NM-B (Romex) connected to 50 amp breaker. Wall connector is set to 50 amp circuit which automatically selects 40amp max current.You're making it confusing by not fully specifying what you're talking about.
The topic of this thread is talking about separate wires in conduit, like THHN type. For that, the 6 awg wire gets to use the 75 degree C temperature rating, which is 65A, not 55A.
Cerrowire Resources - Ampacity Charts
Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Cerrowire's ampacity chart helps calculate the load requirement for a circuit.www.cerrowire.com

This thread is extremely confusing. To answer the OP directly without all these "other choice" options, you need the following:
2x - 6 gauge THHN wire, whatever length you need
1x - 10 gauge THHN wire, whatever length you need
1x - conduit, whatever length you need
Done. See links below as well:

I agree we need inwall and outwall conduits. But Do we need conduit while running these wires in Attic?This thread is extremely confusing. To answer the OP directly without all these "other choice" options, you need the following:

Most likely yes if it is THHN wire. If it is ROMEX (NM-B) than maybe not.I agree we need inwall and outwall conduits. But Do we need conduit while running these wires in Attic?
Maybe there was some problem with nails cutting Romex or fire issues?Freaking Chicago area is ridiculous. They just have a full-stop prohibition on using NM-B cable at all. Period.

Depends on local regulations. I just finished installing the second connector and neither have conduit in the atticI agree we need inwall and outwall conduits. But Do we need conduit while running these wires in Attic?

Yes I should have clarified. I ran Romex. From panel in wall through ceiling and then plastic conduit down to the wall connector since it was punched down through ceiling along outside of the wall.THHN conductors go in conduit. Always.
