The NEC now requires GFCI protection for 240v outlets (GFCI location requirements are the same for 120v and 240v). So if you want to use this for a 240v plug-in EV charger it will not work (though it may be possible to hardwire it). You also can't use this for 240v sub-panels. In both cases you will need to have 4 conductors; 2 hots, 1 neutral, 1 ground. Dryers and ranges also have to be installed with 4 conductors (reason being, even if you don't need the neutral now, someone in the future may swap out the appliance and need it then)

Edit: After rereading what I wrote, probably confused some people when I said it wouldn't work. So, just so there's no confusion, I'll try to do a little bit better. Also, please keep in mind that codes do vary around the country.

The 2020 NEC requires all outlets up to 250v in a garage to be gfci protected (earlier versions only required the 120v outlets). (location dictates which 120v/240v circuits/outlets need to be gfci/afci). Also, there are no 240v gfi outlets (that's not 100% true), so you will have to use a gfci breaker; and sometimes you are given the choice on how many conductors you want, and other times you're required to run 4 conductors. But even if you're not required to run a neutral, it is still a good idea because you won't be able to share neutral and ground if you ever upgrade your appliance (it really sucks tearing out drywall and replacing wire simply because someone didn't want to spend a little extra for 1 extra wire).

All that being said, I've seen plenty of times were the gfci was installed to pass inspection and then removed. (Talking about freezers, frigs, pumps, lighting/fans, and ev chargers since most of those seem to have built in gfi's.) Usually, an way around the gfci issue is to hardwire the appliance. And most ev chargers are quite easy to change over to hardwire.

It's for 240V/50 amp. The 6-50 plug doesn't use a common, so both are hot.

It is cheap, but uf wire is really a pain to strip. If you have a choice definitely go with standard Romex.

This should be good for older electric stove connections but at least in my area new construction requires ground and 4 plug cord instead of older 3 plug. Very good price for 6GA copper wire.

Who runs wire this large for 120v? Would you ground it separately at the terminus?
longer distances require thicker wire. If you are running over 100 feet you may need this no matter the voltage

I used 6/2 when I did a 80 foot run for a 120VAC 30A RV outlet in my storage yard. 8/2 would have been the minimum acceptable.

I'm looking at wiring a 240V/40A outlet to my garage to charge my Kia EV6 and was wondering the same. I think you need a 4-strand cable in order to properly wire an EV charging outlet.

Whether or not a 240V appliance needs a neutral depends on the device. For example, dryers will use the neutral and one leg of the 240V to make 120V and use that for control voltage. Most electric cooktops won't need the neutral, but stoves (with controls) might.

Apparently Tesla's charger does NOT require or use a neutral, so provided the wire is sized properly for the run, this wire should suffice.

Now, other vehicles MIGHT require a neutral though.

anyone know if it is against NEC code to run this instead of Romex in-walls above ground? I know it's meant for underground exterior applications and technically better protected/shielded than romex, as well as more difficult to work with (harder to cut the sheathing). Just wondering about the above since this is oddly cheaper than the equivalent romex version. Would inspectors have an issue if they saw this in your house? They might think it's kinda odd to be running underground cable in place of romex.

Damn, half price compared to 6/2, perfect for NEMA 6-50 plug + 50 amp breaker, may even be up to code for 60amp breaker (48amp draw from tesla wall charger) if you put it in conduit

It would depend on your local code I'd say. Not sure if someone else could answer for your area. My layman assumption is that it wouldn't be an issue.

Burial wire is higher spec and overbuilt compared to romex ...and usually much more expensive. Also as a layman, this should be fine to put anywhere. You dont even need conduit. When I connected my EV charger, I got 6/3 because it came out cheaper than the conduit needed for THNN

The newer tesla and juicebox chargers only need three wires (no neutral) as opposed to four, so you dont need 6/3 wire...this wire will suffice for both. They use a nema 6/50 plug.

This is cheap. Get some if you are even remotely thinking about running a subpanel to another building on your property or if you want to connect spotlights.

Agreed, thanks for clarifying. I ran the indoor version of this I bought by the foot at Lowes recently, I think it was at least $5/ft, but I don't recall. Pretty tough to work with, as it's very thick, but works great with my nema 6/50 to charge my EV.

Yes, with a Tesla 6-50 adapter, and a 6-50 outlet. Don't cheap on the outlet - get a Cooper/Eaton or Hubbell
