I want to use my dryer outlet in the garage to plug in the supplied portable EVSE, but it's on a 30 amp breaker. I can use a NEMA 10-30 to 14-50 adapterto plug in the EVSE, but I need to limit the Ariya draw to 24 amps. This is possible on the Kia EV6, but I can't figure out how to do it on the Ariya.

On a separate but related topic, a little research has shown me that my 10-30 outlet uses the neutral conductor as the ground, and was banned in 1996. It was replaced by the 14-30, which splits neutral and ground into two different wires. If the Ariya (or the EVSE supplied with it) can't derate to 24 amps, I'll have to update the outlet, wiring, and breaker to 40 amps. Might turn out to be nearly as easy, if there's not a 4th wire hiding behind the outlet.

You might be able to install a switch like this:

Edit: sorry, I misunderstood the question. I would expect the EVSE to automatically de-rate, but you should confirm that with Nissan

The supplied EVSE is 32 amps on 240V, and doesn't have any settings to change that. It also has no way of knowing that the outlet can't supply that safely. I'm not aware of any settings in the car that would allow one to set a lower power limit in the car. There are 24 amp EVSE's available though, or ones that can be set for that, such as those from ClipperCreek, Grizzl-e, and the WallBox that reservationists get a discount on. Avoid the cheap ones on Amazon.

DS:
Close. Nothing badly wrong with 10-30, it just doesn't properly support 120V concurrently. It does not, as you suggested above, have a neutral which is why no 120V. It has two 120V and a ground. Well, it does if it was installed correctly..

Can't control current at the OBC? yikes. They do make rate controlling EVSE's (sort of. They send sub-rate pilot signals to the OBC) although they get a little expensive.
