My house only has single-phase power connected to the main switchboard and so the outlet can only support up to 32 A single phase electricity power for charging Telsa. That charging power of 7 kW can be supported by the UMC without having to install the HPWC as far as I understand. The question is if I ask an electrician to install such as a 32 A single phase 3 pin outlet, what kind tail adapter I can use? Tesla Australia is selling a Blue Adapter rated 16 A in its shop which seems to fit the 32 A 3 pin outlet but the current rating is low. Strangely the page says it supports charging power up to 7.4 kW which does not make sense for 16 A current.
