Ground Plate Sphere of Influence
Copper grounding plate assemblies intended for grounding applications have minimum dimensions of 4" x 36" x 0.0625" (100 mm x 2.4 m x 1.58 mm). A 25-foot (8 m) continuous length (no splices allowed unless using exothermic welding process) of 6 AWG solid bare copper wire is to be attached to the plate using an approved welding process.
