I'm getting ready for a Model Y - maybe it will come in January. Meanwhile I need to get my home charging ready. I'll be charging near a detached garage about 70' from the house, and I've decided on the Tesla Wall Connector because I'll be charging outside of the garage (but under a roof).
Garage has existing 120v wiring but I can't use that, it wasn't done up to code. So I need to have a new 240v circuit put in and that will need trenching from house to garage. A couple of electricians said it's best if I put in a sub panel, run the new line to that and run the Tesla Wall Connector from that. So a 50 amp line to the sub panel I guess gives me 30 or 40 amps to the Wall Connector, leaving some room to add 120v outlets or lights on another breaker. One electrician said that an EV charager should be on a dedicated circuit, so gave me a quote for running a 50 amp circuit from the house directly to the Wall Connector, and not touching the existing 120v wiring to the garage.
The dedicated circuit would cost less, but I think a sub panel would give me more flexibility for adding other circuits, although I don't really need that at this point, and I do have the existing 120v line. Are there any other pros or cons for dedicated circuit vs sub panel?
Note: I don't do a lot of daily driving. I'd like 40 amps or more for charging, but 30 should be fine if I can't do more.
