Circuit Breaker Rating / Maximum Output - Tesla Gen 3 Wall Connector Manual

Circuit Breaker Rating / Maximum Output

Power Output
For maximum power output, install a standard double pole 60 amp circuit breaker. Wall Connector
includes integrated GFCI protection - do not install a GFCI circuit breaker.
Wall Connector incorporates automatic load management, which allows the max output to be
customized to an existing power supply. If the electrical supply is unable to support the 60 amp
configuration, select a lower amperage configuration.

NOTE: External disconnect switches are neither required nor recommended.
NOTE: Circuit breaker size is programmed during the commissioning process. See
Procedure on page 22
NOTE: Some Tesla vehicles may draw less current than the max output. Actual charging rate depends on
Wall Connector output and onboard charger in the vehicle.
Branch Circuit Conductors and Ground Wire
• If installing for less than maximum power, refer to local electrical code to select correct conductors and
ground wire size that are suitable for the chosen circuit breaker.
• If installing for maximum power, use minimum 6 AWG, 90° C-rated copper wire for conductors.
NOTE: Upsize conductors if necessary.
• For sites with multiple Wall Connectors, each Wall Connector must have its own branch circuit with L1,
L2/N, and Ground.
• COPPER WIRE TERMINATIONS ONLY for landing in Wall Connector wirebox terminals. Conductors can
be stranded or solid.
• For outdoor installations, use watertight fittings when securing feeder wires to the wirebox.
Grounding Connections
Wall Connector must have a ground path back to the main equipment earthing point on site. Without a
proper ground connection, the Wall Connector will fault during a ground assurance test. Equipment-
grounding conductor must be run with the circuit conductors and connected to the equipment-
grounding terminal in the wirebox. Install a ground (PE) wire sized according to local electrical code.
