I can’t recommend an electrician.
But I’ll give some advice (assuming you have an SR+):
- mobile connector bundle with a NEMA 14-50 is enough to charge your car.
- I would install a NEMA 14-50 in both homes and maybe buy one or two spare mobile connectors (if you’d like)
If you have an LR, the Tesla wall connector will always provide the best charging speed.
Congratulations, you’ll love the car!
