Nec Code On Ground Rods at Clifton Curran blog

Nec Code On Ground Rods. National electrical code and requirements for ground rods section 250.53 of the national electrical code provides grounding electrode installation rules that apply to grounding. According to 250.53(a)(2), a single rod, pipe, or plate electrodes needs to be supplemented with an additional electrode unless it can be proven that a single rod, pipe, or plate grounding electrode has a resistance to earth of 25 ohms or less. 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). Installation of these components of a grounding system needs to be done correctly and in compliance with the nec. As can be seen by the intro photo, driving ground rods can be difficult work depending on what part of the country you are located in. The national electrical code (nec) article 250 does not have a requirement for how far the grounding rod needs to be placed in relation to the electrical panel. Generally speaking “best practice” would indicate that the closer you install the rod to the panel, the better.
