She has her unit set to 48 amps and it says it’s pulling 48 amps…guess it’s wrong.

 

60 amp circuit should be 4 gauge wire IMO. For a short run 6 is okay but not ideal. For a long run 6 gauge 60 amp circuit makes me cringe.

 

If she's pulling a continuous 48A through a 14-50, what do you think will happen when her house burns down? The charger and the outlet are not UL approved for that configuration. I'm surprised the charger doesn't know better, but I'll take your word for it. I really don't understand your defense of your neighbor's code violations, but are all concerned with a someone doing a simple DIY outlet change. LOL

 

I’m not defending anything, I wouldn’t do that. I would run it at 40 amps on a 50 amp circuit.

I also never said anything against a DIY outlet job, I said I wouldn’t have a handyman replace outlets unless they are licensed to do so.

 

For a 60A circuit, 6 gauge is fine for the hots. You can use 10 gauge for the ground. 3 wires total. You don't need the neutral, like you would for an outlet, if hardwired.

 

Good. I hope she's not your nextdoor neighbor. Who installed a 14-50 on her 60A circuit, a handyman?

 

She is. An electrician. I’ve talked to several who have no issue with that setup despite it being against code. I still wouldn’t do it

 

Code here says 40+ feet you drop down to 4 gauge. Tesla has a nice guide they say 6 is fine for up to 150 feet on a 50 amp breaker.

Here is the specific plug Tesla recommends

That's the mobile connector, which I also have. I was using that up until the time my permit was finally approved and had my wall connector installed. It has a max current rating of only 32A. Canada, not sure of your area, also allows a 14-60 outlet for EV charging. That's not allowed in the US, but I'm sure it's done. Steve's neighbor should probably switch hers to that, at the very least.

That is a quality outlet, so I understand why it's recommended.

 

This configuration will be permitted for individual localities that have adopted NEC 2023. However, currently only Colorado, Massachusetts, Oregon, Texas and Wyoming are there. Most places are still on 2017 or 2020, with some backwaters are as far back as 2008.

However, if you're going to the trouble of replacing the outlet AND the plug on the charger (14-60 is physically different than 14-50), might as well just hardwire it.

 

Yeah makes no sense to try and adapt a 14-60, and I haven’t seen any chargers that have a 14-60 plug.

 

Because of this discussion, I've actually found one: LINK

And here's a thread from a Rivian forum regarding its use: LINK

 

I've not seen specific reference to a 14-60 in NEC 2023, but I'm only an electrician on the internet. Well, I did work as an apprentice for a friend who is one, back in the early 80's. It was enough to motivate me to go back to school and get a degree.

That different pin on the plug is actually for the unused neutral. You can just cut it off!

 

Haha
I hear that.

It's a much harder job than people think.

When I looked into it years ago I was told by a few people that you will spend the first few years of learning in attics and crawl spaces and doing what they called the "grunt work" until you know what you are doing. Lol

 

Oh wow…cool
