• Rated for 60A service to allow for a fully loaded C7004/C150 system per NEC in the United States or
internationally, per local safety codes.

Apply a coat of anti-oxidant paste to unplated metal contact surfaces before you make the cable
connections. File unplated connectors, braided straps, and bus bars to a shiny finish. It is not necessary to
file and coat tinned, solder plated, or silver-plated connectors or other plated connection surfaces, such as
those on the PEM studs.
