Nec Requirements For Ground Rods at Richard Mckillip blog

Nec Requirements For Ground Rods. Ground rods are critical in electrical grounding systems, providing a safe pathway for excess electricity dissipating into the earth. If the ground rods are your only electrode at each building then you will need 2 unless you can prove the single rod is 25 ohms or less (never done). The grounding electrode conductor to a ground rod that serves as a supplemental electrode is not required to be larger than 6 awg copper. The length of rod and pipe electrodes is located at 250.52(a)(5) in the 2017. Generally speaking “best practice” would indicate that the closer you install the rod to the panel, the better.
