Can I Charge With This Plug?

[Talenhtucker]

Hi everyone,

Just bought a house and I’m looking at home charging options for my 2020 Long Range M3. I drive ~60 miles per day and have charging at work, but would be nice to have options at home (don’t need anything super fast).

Looks like there is a 250V/20A outlet in my garage. Does anyone have experience charging their Tesla via one of these outlets? Found an adapter that might work here:

Looks like I’d have to get a NEMA 14-50 adapter as well, and I’d have to manually adjust charging to 16A to avoid overloading the circuit breaker.

Thanks in advance!

Safest solution would be to change the outlet to a 6-20 and get the 6-20 adapter from Tesla: Gen 2 NEMA Adapters

Less desirable would be to leave the outlet and get a L6-20P to 6-20R adapter as well as the Tesla adapter.

It looks like someone had a Nissan Leaf charging outlet installed in your garage. This adapter will work with our Gen 2 UMC, no other 14-50 adapter required. Oh, and the adapter has internal circuits that will set 16amp charging, so no need to manually adjust anything.

Don't forget to check the circuit panel to make sure the breaker has the correct size for it.

its pretty easy to convert it to a regular 6-20. The nice thing about 240v 20 amp is that it uses the same wire as 120v so its as easy to work with as normal house wiring. I've charged with a 6-20 outlet for 18 months now and have had no trouble, even when I was doing 100+ miles a day. I did get in the habit of checking the charge when I woke up in case I forgot to plug in the night before as there's no "quick charge." I am planning an upgrade to 14-50 soon.

Yep. I used something like that to charge from an old style dryer plug. Please be sure you reduce the current first - I noticed that mine kept a "memory" in this scenario and when I replugged it the the charging amps were still at the lower setting.

This was at a friends house though, for your home I agree with those that recommend changing the plug.

Since it is in conduit would it be relatively easy to pull new wire and install a 14-50? Since I don’t know how far away your panel is I’m asking.
