@paco @BenAveling it is just a stupid electronic device

@h3artbl33d no worries. It’s one of those times where the message was so short and we don’t know each other, so the tone didn’t come through. I can see the joke now.
And the book is 20 years old. Just as FreeBSD 5 was coming out. there isn’t much to learn there. Don’t waste your money or time.
All I meant about the breath of fresh air is that I’ve been doing disk partitioning the hard way on FreeBSD so long (even sometimes using sysinstall to avoid the CLI tools) that this was super easy and nice.

@paco You can get a configurable EVSE that will limit what it will draw. As an example, I have a J+ Booster that I have set to 24A on my 30A circuit. I do use an adapter since it came with a 14-50 plug.
Adapters are kinda frowned upon for these kinds of cases, but so long as you can limit the draw, it should be fine.
In your case, I'd probably limit it to 16A or 20A since it's shared with something else and you want to follow the 80% rule on a circuit.

@paco I have 2 'mobile' EVSE chargers that have adaptors for various plugs - none for this plug type though.
Both of the chargers allow you configure the maximum amps to allow the car to pull, since, as you note, some of these plugs are for lower amp circuits. By default, for safety, the chargers are configured for low amps until you tell them otherwise.
An external adaptor should be ok for short periods. Heat can be a problem for long charging, so quality matters here.
Here's one of my chargers on Amazon, with photos of the 4 adaptors it comes with.

@bedast Super helpful! Thanks!

@craz8 awesome. Super appreciate it.

@paco Not keen on pigtails. If the charger's not hard wired, perhaps have a socket added to match the plug it ships with.
-
@paco you want to look for RV style adapters to get you to the right plug and make aure your L2 charger can handle the max 50A but I would get a consult from an electrician to ensure you have perhaps have a limiter on the EV plug so you don't overdo it and keep Code happy

@lopta can’t add just a socket that is the right shape. That’s a 50A plug. I’d have to have an electrician add a 50A circuit behind that socket. I don’t have that kind of capacity left in my panel. I have a LOT of electric stuff going on. Electricians told me I’m pretty much full. That’s why I need an adapter for the plugs I have, and some method of making sure it doesn’t draw more than I can handle.

@paco Perhaps a 4kW charger that plugs into a NEMA 6-20? Modest but a nice step up from 120V 15A.

@chris no no, you misunderstand. My 240V circuits have 30A breakers and a standing load of 1-2A. I need to make sure the charger does NOT try to pull more than 20A, and I need to use the circuits and sockets I have.

@paco The amount of current that goes to the car is limited by the charger (and the car, of course). So, it's up to you to set the charger to a current that's small enough so your plug and circuit can supply it.
AFAIK, the charger doesn't have any way of knowing what size circuit breaker it is attached to.
Oh, also, you're not supposed to use 100% of the capacity of your circuit breaker in the long term. For instance, on a 15 amp circuit, you're not supposed to set the charging current above 12 amps.

@paco Also, AFAIK, the charger doesn't know about adapters.

@cpr320 Exactly. I’m trying to find a charger that will (a) plug into the socket I have, and (b) let me limit its draw. I can find (b) but not (a).
Maybe I just need a regular 14-50 plug and an adapter to the L14-30R.

@paco I think so.

@paco ah! my mistake. hmm that's a difficult one. I would definitely get an electrician's advice. There are a number of the L1/L2 chargers that are marketed as RV campsite rated that should have the correct plug but ya. electrican advice
-
@paco I have no helpful advice, but your situation did bring to mind this recent #xkcd on universal sockets

Welp. @steggy called it. It lasted about 45 minutes. I’m getting ready for bed, I’m taking off my wedding ring, and my finger slips. Somehow (absence of sobriety may be a correlated event) my fingers slipped and the thumbnail of one thumb cut a gash in the other. Ouch!
Ok. Regression to the mean, right? It’s gonna get a little better now?
