The wall connector charging station by Tesla is a Level 2 unit, requiring 240 volts to charge. Before installing your Tesla wall charger, you should look into your electrical circuit breaker amps and the maximum miles of range per hour of charge it will provide. For most Tesla models, a 60-amp circuit breaker provides the fastest charge rate.
The second-generation wall connector delivers up to 80 amps to the vehicle, and the third generation delivers 48. Though the amperage in the new unit is less, 48 amps is the new industry standard, so it will meet your needs.
