Bentleytn, in your PM to me you responded that the outlet was a NEMA 14-50 (!), that the circuit has two 35A circuit breakers, and you mention that the (portable?) Nissan Leaf EVSE is rated for 30A.
Sounds to me as though that EVSE has a NEMA 14-50 plug on it, which would be proper for a 30A draw.
However, earlier in this thread you also mentioned that "you had a 35A circuit breaker put in" and that you are using a "dryer outlet". Did you or someone also replace the dryer NEMA 14-30 outlet with NEMA 14-50 to match the connector on your Nissan Leaf EVSE?
First off, DO NOT TRY TO USE THIS RECEPTACLE UNTIL THE PROBLEM HAS BEEN IDENTIFIED AND A SOLUTION IMPLEMENTED. This is how houses burn down. Your Bolt can be quite happily charged on a daily basis using its own portable EVSE plugged into a plain old 120vac 15A wall outlet.
Unfortunately, we still can't see any photos and don't see any link within your posts.
A dryer outlet is normally NEMA 14-30. You must not just exchange its 30A circuit breakers with 35A circuit breakers, or replace a NEMA 14-30 receptacle with 14-50 receptacle without also addressing the wiring going between the breaker panel and this outlet (assuming the overall breaker panel capacity is sufficient to handle 50A).
First off, a 35A circuit breaker in each leg of the split-phase 240vac is still 35A (it is not additive). 35A is an unusual value, as a 14-50 outlet I would expect to have 50A circuit breakers. Again, are you sure the receptacle is 14-50 and not NEMA 14-30 (they look similar, but the Neutral prong on 14-30 has a bend to it)?
14-30 is what is normally installed for dryers, and the maximum continuous current you should be drawing from it is 24A.
Your Bolt will be trying to draw 30A, as instructed by that EVSE. Remember, your Bolt can draw up to 32A if an EVSE allows it to do that.
As others have pointed out, 80% of 35A is 28A which should be the maximum steady-state current you should be drawing from this circuit. Thus, your Nissan Leaf 30A EVSE is already telling your Bolt to draw too much current from this circuit.
That said, and with a 35A circuit breaker, I would not expect a "Melted 240 Outlet" as the NEMA 14-50 receptacle is easily capable of handling 40A continuously. I suspect that either the wiring inside the receptacle was not properly attached and/or the wires going from the circuit breakers to this outlet are undersized.
With the circuit breakers turned OFF, that receptacle needs to be opened up and examined, as well as the wiring going to it. If it has been subjected to heat stress, the receptacle needs to be replaced.
How long is the run from your circuit breaker panel to this receptacle? Depending on the wire type and its length, I would expect a wire size of #6AWG or #8AWG in there. Anything smaller (in physical size) is asking for trouble. Don't risk it!
Since the Bolt does not have onboard 240vac current adjustability, the only way to tell the car to reduce this current is inside that EVSE, and I don't believe that feature is adjustable on the Leaf portable EVSE (anyone?).
If you'd like to use this EVSE, it should be plugged into a circuit that contains circuit breakers AND wiring AND outlet that will handle 50A. NEMA 14-50 meets this need.
Enough food for thought - your best bet is to hire an electrician or ask a knowledgeable friend to help out.
If you want to continue using that "dryer outlet" and the wiring is undamaged, plan on using an EVSE with adjustable current so as not to draw more than 24A - I'd use 16A for a while and make sure nothing is getting warm before increasing the current.
Apologies for being repetitive, but overheating receptacles/wiring is one of the more common causes of house fires.
Let us know of your progress.
