My wall connector has arrived in anticipation of my Model 3. I have a friend who is an electrician providing some advice when getting quotes for the install. He states the difference in material cost is minor for higher amperage circuits and planning ahead on the circuit size is a good idea. He isn't familiar with the details on how multiple WC's work, however. The Model 3 LR will charge at a max of 48 amps which would require a 60a circuit. There's a good probability we'll end up with a second Tesla at some point and utilizing two wall connectors with the communication link would be ideal. With this in mind, would it be logical to install an 100a charging circuit now to the single WC? Clearly, a single wall connector would use roughly half of that, but adding a second connector in the future would avoid redoing the original install to handle the higher current. Short of the higher gauge wire, different breaker, and an external power switch to the circuit, the cost of the labor would be similar. Am I approaching this the right way? Those that have installed second Wall Connectors, did you have to redo the original install or did you run a totally different circuit to the 2nd WC? I don't want to overdo a straightforward install, but I don't want to pay again to upgrade the first connector's install... assuming I'm understanding this all correctly.
