I ordered the Model S with a HPWC, but now found out from my electrician that my house electric can only support 50A more. I do want the twin chargers, but kind of wondering what the benefit would be of having a 14-50 outlet installed versus actually connecting up the HPWC. Kind of hard to justify $2500 for just having a spare cable in the trunk. I don't think it charges faster via HPWC @ 50A? I saw on the forums somewhere that Tesla might take back the HPWC and credit some of the money? Any and all help is appreciated!
