Hello, I'm exploring my options. I'm converting a 110v outlet wired with 12/2 gauge (110v/20A) to a 240v. Since the maximum possible current is 20A with this 12 gauge is 20A, my only option is to replace it with NEMA 6-20 (240v/20A). Tesla doesn't sell 6-20 adapter, but it does sell 5-20 adapter. What would happen if I used the 5-20 adapter? Does the internal charger adjust itself depending on the installed adapter? I'm a bit confused... I noticed some people created their own adapter from 6-20 -> 14-40 but I'm not sure how the internal charger would know that the maximum available current is 20A (or 16A continuous) to avoid overloading the breaker and triggering it. Please advice. Thanks!
