I had a HPWC installed on a circuit breaker that doesn't get a ton of power, so they installed it at a 40 amp setting which according to both the electrician and the Tesla web site should be good for 23 miles per hour of charging. (Home charging installation)
It's only getting half that - 12 miles per hour, consistently. When it's plugged into the car the app shows it charging at 16 amps (with 32 amps greyed out and no apparent ability to switch it on). Is this the way it's supposed to be?
I don't have the high amperage charging option, but I didn't read the original web page to suggest the 23mph rate required that option. And the description of that option implies I should be getting way more than 12mph even on on 40 amps without the high amperage charging. ("Model S comes standard with a 48 amp onboard charger, allowing up to 34 miles of range per hour of charge with a Wall Connector. The included Mobile Connector can charge at a maximum of 40 amps, allowing up to 29 miles of range per hour.")
So why shouldn't I be able to get the full 23 with my HPWC at 40 amps? Any ideas?
TIA
