UO65P is a disconnect box, that is not required. 60 Amp line is good, you can purchase Charge Point Home Flex wall box and run it at 48 Amps. Remember EV charging is a constant load for hours at a time, so you want to always pull 20% less than the circuit max capacity. It looks like the required plug is NEMA 6-50 or 14-50. Here is the unit, this is the top of the line, and you may get a rebate from your local utility, I just got $500 off on mine. Check with your local utility company. In the area I live we typically use NEMA 14-50, and make sure your contractor GFCI protects the circuit which is required under the 2017 electrical code in the USA. Many contractors are still unaware of this change in the code.
