12 gauge wire in most cases. The type and length of earth ground rods vary
by region. Contact the AHJ (Authority Having Jurisdiction) in the municipality
where you plan to install the CAPXL / CAPXLV for correct grounding materials
and installation procedures. A proper ground is critical to minimizing risk for the

1.
Connect the ground wire (12 AWG or larger) to the CAPXL / CAPXLV main
earth ground connection.
2.
