Copper bond earth rods are the ideal driven earth electrodes, as they offer the installer an economical and efficient earth rod grounding system. Pure electrolyte copper is uniformly molecularly bonded into a high tensile steel core to a minimum thickness of 0.254 mm, as UL 467 (1996) States:
“The copper jacket shall not be less than 0.010 inch (0.25mm) thick at any point and shall comply with the adherence requirement and bending requirement thus ensuring excellent corrosion resistance and eliminating electrolytic action.”
Deep driven Petunia copper bond earth rods are an economical method of achieving a low earth resistance.
