Do you already have an electric car or is that the next project?
We have two: a Chevy Bolt (all-electric, ~250mi range) and a Honda Clarity (plug-in hybrid, ~50mi electric range). And a charger in the garage at home. This project was to hook up a level 2 charger that I got on Amazon earlier this year for our cabin in Maine.
Actually, the Bolt was our 3rd electric. We bought a Nissan Leaf early on, then traded it for another Leaf, then traded that one for a Bolt. I admit, we gamed the tax incentives.
