I had an electrician over on Friday and got the wiring done for adding 240V charging in my garage. He put in a sub panel which can handle up to 60A. Initially I had just wanted a 30A outlet for the Roadster but then thought about future proofing a bit in case we get another EV down the line. The guy mentioned getting a level 2 EVSE instead of the typical NEMA outlet since they're safer, reliable, etc. But these chargers run about $400-500. He recommended used Bosch ones on eBay though I'm a bit skeptical of buying used, especially given how much current and voltage these things handle. I do worry about my future kids accidently messing around with a 240V outlet, but feel that it would allow more options in case we don't go with a Tesla, or need the outlet for tools. Any thoughts? I usually do most of my charging at work where we have several Chargepoint stations that give free charging at 220V, 30A so honestly I try to charge at night to spend as little as possible! For us peak rates in the summer go up to 30 cents/kWh!!! And already spent $1500 on this job, though he also wired a generator hookup to the house. I live in New York and don't know if there are any rebates or tax credits for EV charging.
