>My understanding from technology connections is that US circuits are 230ish volts, but it’s often centre tapped out to sockets.
Indeed.
My heat pump is 3phase 230v/16A one, that's 11kW peak power, the pump itself is 5kW, though with the rest being a resistive heater. Car charging is similar as well 3phase is quite standard nowadays.
My understanding is that the US power supply is pretty similar to the one in Europe when it comes to delivery, and industrial equipment runs 3phase, 240v - something you can find at a lot (most new) homes in Europe.
