I have an existing 30A 240V circuit (3 wire, with ground) in my garage that is no longer being used for anything else, and I could re-route the cable and receptacle NEMA 14-30) to a more convenient location for charging my Model Y. I could also free up space in my breaker box for a new double pole breaker, and install a new circuit with some spare 8 gauge cable (2 wire, with ground) I have; I'd use this to put in a NEMA 10-30 receptacle. I don't require anything more than a 30A charging capability for my needs, so my question is whether there is any advantage to choosing one NEMA version over the other if I have the choice. Thanks.
