We have an electrician coming so this is not a "how do I" thread, It's more for me. I THINK the electrician is going to run a sub panel off of an existing sub panel. The breaker in the existing will be 60a with a run to two 60a breakers in the new sub panel. Those will feed our new wall connectors. If power sharing is not yet enabled between gen 3 connectors then how will this work? I am assuming that both cars can not charge at the full rate since they both share 60a. Will the cars self regulate to not overload the single 60a supply in the first sub panel?
