Not legal and definitely not easy to get local without a license. There’s always someone will to sell on the black market. Also, shit is dangerous if you don’t know what you’re doing. I was trying to give the OP sound advice, you know, what they’re asking for.
I work for a trade company and have access to at cost electrical work, have enough capacity in my panel, and yet we still haven’t felt the need to add wiring for a level 2 charger since it fills from empty in about 8 hours. Pretty much saving the upgrade for when we buy a full EV.
