I agree with these. I ended up waiting until now to get my 2020 FXS and I was so hoping these would be in there. Why not max out a 20A circuit?!
A 20 amp household breaker should not have more than 18 amps on it. It's "code" for most electrical wiring of houses, etc.
I have my Tesla Wall Connector on a 60 amp circuit breaker and I can only use 48 amps max. The wiring is also for 60 amps.
No electrician will go over the 80% rule, AFAIK.
So for a 20 amp circuit, expect 18 amps max per house fuse or circuit breaker. And most equipment wants to say well under that, as you may have other stuff on another outlet coming from the same breaker.
IIRC, our Zero OBCs draw around 13 amps at 120 VAC (~1500 watts AC input). Half that at 240 VAC, around 6.5 amps, which is stupid, IMO.
My Energica current stays the same as the voltage is increased so it has 1.5 KW charging at 120 VAC and 3KW charging at 240 VAC. Why Harley and Zero does it differently, I have no idea, but most likely because it is cheaper and less heat when 240 VAC is used compared to the Energica chargers.
