@Stinson_108 @LilahTovMoon Tesla home chargers are AC - that is why you can AC charge Teslas on other vendor chargers - lookup the specification for J1772 (they send a 1KHz PWM signal to select charge speed).

Fast chargers are DC but cost a fortune and are not used at home unless you have a seriously oversized supply and stupid amounts of cash.

In any case the vehicle should be connected to the local earth via the connection - this is a basic safety requirement.
