I only have a single charger on my vehicle, but purchased the HPWC because I wanted to keep my UMC in the car at all times. When the electrician was hooking it up, I had him go ahead and install it on a 100amp breaker in case I ever wind up adding the 2nd onboard charger in the future. Since I can only charge at 40amps, I've left the dip switches on the HPWC at the 40amp limit. However, occasionally I'll have a PlugShare driver come by with dual chargers. Should I just leave the dip switches set to 80amps and just let the car handle the charging at 40amps so I don't have to take the cover off and switch the dip switches back and forth? Thanks!
