Concrete Encased Electrode requirements specify how much concrete encasement?

Explanation:
Concrete-encased electrodes are part of the grounding system, and the surrounding concrete thickness is part of ensuring a reliable, stable path to earth. The requirement is that the electrode be embedded in concrete with a minimum of two inches of concrete encasing it. This thickness provides a durable, moisture-rich pathway that maintains good electrical contact with the surrounding concrete and soil, helping keep the impedance low and protecting the electrode from physical damage. So, the minimum concrete encasement specified is two inches.
