An HPC was included with my roadster when I bought it (used), but I only have 60 amps available in my garage. Can I install it and set the max charging rate to 48amps on the charger? The install guide implies this ability with a chart showing charging rates based on 80% of the breaker rating, but it doesn't say how to about tell the charger its connected to a 60amp breaker. I know I can tell the car to charge at a specific rate.
