Electrical work begins tomorrow on the barn/garage. New 200Amp service with HPWC and 14-50R branch circuts for the S. The 14-50 will be a backup for the HPWC. After we do the testing on the HPWC in test mode, I plan on setting the DIP switches to 80 amps as it is going to be on a 100 Amp SquareD QO breaker with appropriate copper wires. Now my S will only have one charger so it will max out at 40 AMP draw. I plan on being a part of PlugShare so would like my HPWC to be able to charge model S's with dual chargers... I understand that my S will only draw the amperage that it can handle with one charger.... is that correct? Any downside on having the DIPs set at 80 if I will only usually draw 40???
