• For use on all 5/8" diameter UL Listed copper-clad ground rods.
• Used to bond one or two, #4 or #6, solid copper conductors respectively.
• Produced from high-strength copper alloy, the same material as UL Listed "acorn" type ground rod clamps.
• May be used effectively for direct-burial applications.
• To install, the only required tool is a hammer. Compression forces maximize the “direct” surface-to-surface copper contact between conductor and ground rod electrode.
• A drive-head should be used during installation of the ground rod electrode into the soil, thus minimizing any possible mushrooming or deformation on the drive (or chamfer) end of the rod. This will improve ease of installation of the drive-on clamp.
• This design places the grounding conductor in “direct” contact with the ground rod, thereby eliminating multiple paths for the current to follow, which could contribute to increased resistance.

TO INSTALL:
• Select the proper connector from the above chart.
• Drive the ground rod electrode to the proper depth per national or local code recommendations.
• Position connector and ground rod conductors as shown in middle illustration.
• Drive connector onto rod until top of connector is flush with top of ground rod as shown in adjacent illustration. Galvan suggests using a 20-ounce hammer.
