Great info, thanks! Comparing to the standard 13A plug next to it, I would imagine it could be the 16A/3.I need to sneak over there late at night and suck some juice - as the local shopping mall carpark only has 13A (at 24 HKD/hr!)The IEC Red connectors are 380VAC 3 phase in Hong Kong. There are two sizes that indicate the current capacity, 16A or 32A. If the outside diameter is approximately 7cm, it is 16A, about 8cm is 32A. These correspond to the capacities of the Model S single and dual chargers, 11kW and 22kW.Edit: There is one more, about 9cm diameter would be the 63A version - 42kW.
