According to NEC, what is the requirement for grounding electrodes in new constructions?

In new constructions, the National Electrical Code (NEC) stipulates that grounding electrodes serve a crucial role in ensuring the safety and reliability of electrical installations. The requirement for at least two electrodes is established to enhance the overall grounding system's effectiveness. This redundancy helps to ensure that if one electrode fails due to soil conditions or other factors, the second electrode can still provide an effective path to ground.

The recommendation of two electrodes supports a more reliable grounding system that can handle fault conditions more effectively. It minimizes the risk of electrical shock or equipment damage caused by overcurrent situations. This requirement is part of a broader goal of maintaining safety standards in electrical installations, ensuring that structures are adequately protected from electrical faults and lightning strikes.

The assertion that electrodes are optional or that only one electrode is sufficient does not align with the NEC's emphasis on safety and reliability. While grounding is indeed not universally required in all scenarios, in new constructions, conforming to the NEC requirements for multiple grounding electrodes is essential for ensuring proper grounding practices are followed.
