I generally agree — go with the hardwired EVSE. Just check to make sure that each link in the chain (i.e., the panel, breaker, and wire) are all compliant for the constant load. If you have to run new wire or install a subpanel, consider future prodding with the biggest gauge wire you can. As you might have noticed, new vehicles like the F150 Lighting are already advertising 80A EVSEs. In addition, should Rivian and/or future technologies allow for V2H/G, you will also want the more capable wire (lower gauge number).😉As long as your panel has the capacity, I’d go with the 60 amp breaker and hard wire the EVSE. Charging speed shouldn’t be an issue on L2 charger. That mostly applies to L3 DCFC charging.
