We just moved into a new house, and in the back of one of the garages was a NEMA 6-20 outlet. I think it was used for an air compressor previously. It uses 12-2 G NM-B Romex to the main panel where there's a 15 amp/240v breaker.

Since the 6-20 outlet is rated for 20 amps, can I just swap in a 20 amp breaker and charge my car at [email protected]?

Also, if instead I remove the outlet and run that 12-2G wire directly into a 1st Gen HPWC, can the HPWC be set for that particular power input?

Otherwise I can gerryrig a NEMA 10-30 adapter with my UMC and just set the charge current in the car appropriately.

Thanks.
