@Tesoso Don't feel bad if you can't get L2 charging setup as cheaply as
@Shelburne or
@euro.r. The cost really depends on what's needed for your home, especially if you don't have an electrician neighbor hooking you up for almost free.
In my case I paid $1300-ish (I forget the exact amount) back in 2014, and that was the cheapest of six (6) estimates/quotes I got, when paying for the electrician to handle permitting as well. Some installs are just more complex than others, and of course skilled service labor costs vary wildly based depending on where you live.
In my case I needed a main breaker upgrade, and also needed somewhat complicated in-wall + in-ceiling run, to get from the back of my home (electrical panel) to the garage in front.
Also, I STRONGLY RECOMMEND you get a Tesla Wall Connector. Don't bother with a NEMA outlet for daily charging in your own home anymore. That
used to make more sense, because the original Tesla Wall Connector was like $1500, and but now a Wall Connector is way cheaper, and electrical code has changed so if you put a new
outlet in for car charging (not hardwired wall connector) it must be on a GFCI breaker which is extra $$$ and often has nuisance trip issues. Plus the newer Tesla mobile connectors are only 32A max charge rate instead of 40A like the original ones.
So I have a NEMA 14-50 at home because back in 2014 it made more sense, but now I would never bother with that, unless it was just at like a family member's home where I just want the ability to charge on occasional visits. At my own home I would 100% put in a Wall Connector now for daily or frequent charging use. Safer, more reliable, nicer cabling, faster charging, and roughly equal cost (vs extra mobile connector + high quality 14-50 outlet + GFCI breaker). And the Tesla Wall Connector has pretty good power sharing capabilities should you ever need those in the future.
