Hello-I am new to the group (first post!) Anyhow, a techincal question about the output of the Tesla HPWC when chaining 2 together on a shared 60amp breaker. Right now we have one Model S that charges at its maximum rate of 48AMP and charges at a rate of around 30mph using our HPWC unit. We are in the process of purchasing second Model S that will probably have the same maximum charging rate of 48AMP (roughly 30mph), and we are considering chaining a 2nd HPWC unit to our existing one. QUESTION: If we were to chain two HPWC wall chargers on our same 60AMP breaker, what would the output be if we were to charge BOTH vehicles at the same time? Would it simply be 15mph?. AND, if we were to charge either car by itself (one car charging, the other unplugged completely) would our output still be 48AMPs (30mph)? And, would that be the same for both the "Master" and for the "Slave" charging unit? I assume there would be a setting that would allow that, but not sure. Anyone out there that has experienced this or with educated input?
