I searched and was not able to find an answer to my specific questions. I have had the X for about a month now and had a Nissan LEAF prior. For three years charged the LEAF using an ESVE on a 40 amp breaker. This has been working fine with X but I would like to use the UMC so it is easier to plug and unplug the cable. The ESVE uses a 6-50 plug. when I installed the 6-50 plug I ran 3/3 AWG (?) wire and put in the 40 amp breaker. I am planning on changing the outlet to 14-50 tomorrow and will connect the currently unused neutral in the 14-50 outlet. So I have two questions. 1) Do I need to change the breaker to 50 amps or will the UMC work with a 40 amp breaker? If I keep the breaker at 40 amps do I need to change any setting on the X or will this happen automatically? I am fine with a 40 amp breaker and 20 mph charging and do not need the extra few miles a 50 amp breaker would provide. 2) If I move up to the 50 amp breaker the 3/3 awg wire will be sufficient, correct? I am pretty confident it will but want some reassurance. The wire says "3 awg with 10 awg ground". The ground is solid and the other wires are twisted. It has been almost 4 years since I put the wire in and have never had any issues at all. Thanks for any feedback!
