Oops I don't speak electricity. The wall outlet provides 60 amps28 amps or 6,720 watts.
A 40 amp setup would work fine, but if you want to future proof it, a 50 amp will also work if you want to spend the extra money.
How much power is your current L2 providing?
For a Leaf there’s only the lv3 chadmo and basically no one puts one of those in their house. It’s DC for one thing I think.Thanks
