So my breaker box doesn't have enough space to add another (and too costly to run a new wire from it anyway) so the electrician suggested to use the wire thats already outside that goes to the AC unit and attach it to a new smaller box and an inverter, then connect the AC from there and run a new wire to where I'm going to install the Wall Charger. Now the AC unit is attached to a 60amp breaker, but the electrician says the AC is only using up to 13 Amps, so I have 47 free to use. Does that sound right? Can I set up the Wall Connector to 40 amps then? Any info/guidance/further details on this would be helpful.
