A:AnswerI think you mean J1772? Very different. This is NACS (Tesla standard) and J1772 is the old school Level 2 charges that other cars have been using. All (most) car manufacturers are moving to NACS.
A:AnswerNo wall plug. This Tesla Wall Charger must be hardwired to your electrical panel. THe Mobile charger can be plugged into various outlets with adapters for several types of outlets.
A:Answeryes, if it is THHN wire can handle more heat plus the charger will only pull 48amp 80% of breaker size.
If you put in 50-amp breaker it will pull 40 amps not much difference on a full charge it will save about an hour charging time but what's the difference, it is still an overnight charger basically
A:AnswerYou can use a 40 amp breaker, but you might limit or slow down the charging speed. The charger really wants a 60 amp breaker, but you should be okay with a 40.
A:Answerthat is actually based on your vehicles battery size and limitations of the car. for example this unit can be wired to a 60 amp breaker, and still only produce a max of 48 amps. but your car and wire size will be detected and max out accordingly. in a 48amp scenario on a tesla you will see around 13kwh which is about 32mph give or take your sizes.
