¹ Depending on local code for installation methods and cable sizing calculations.

Note

Refer to local codes and standards for correct wiring practices and wire colors.

(3) Wago lever nuts are provided for use with up to 6 mm² (10 AWG) cable. If 10 mm² cables are required per wiring methods, other appropriate connectors may be used, or a junction box near the Powerwall can be used to convert from 10 to 6 mm² cables. Follow all code wiring requirements.

Note

Suitable wire ferrules may be used with Wago connectors, but are not required.
