Not an easy installation.
This Tesla Wall Connector works exactly as intended. In order to charge at 80 amperes (maximum for this unit), you have to wire for 100 amperes and use a 100 amp circuit breaker. This is because the National Electrical Code requires that any circuit breaker that has to operate continuously (I.e. more than 3-4 hours at a time) not be loaded to more than 80% of its nominal value. For a continuously operating 80 amp device, this means a circuit breaker rating of 80 amp/ 0.8 =100 amp. To have a 100 amp circuit, you need to use 2 gauge wire which is VERY stiff and difficult to bend and fit into a box. Theoretically, since the charger draws “only” 80 amps max, you could get by with 3 gauge wire which is slightly easier to work with. But a 100 amp circuit breaker requires 2 gauge wire.
The clamps for the wires inside the charger are located very deep inside and the holes for the wires cannot be seen directly. Manipulating stiff wires into these holes is VERY difficult. The wire clamps have to be VERY tight to prevent arcing because of the high current draw.
If installed correctly, this unit works very well. Install is not for the faint of heart.
