Where should connections to ground electrodes be made?

Connections to ground electrodes should be made below grade level and not less than 2 feet from the foundation wall to ensure optimal grounding performance and safety. This placement helps to mitigate the effects of lightning strikes and other electrical surges.

By locating the connection below grade, it minimizes the risk of physical damage, as it is protected from surface disturbances and environmental factors. Additionally, being a safe distance from the foundation wall helps in preventing the potential for coupling with other structures, ensuring that the earthing system functions effectively in dissipating electrical energy into the ground. Grounding electrodes need to be well embedded in soil that has adequate moisture content, and proper depth and distance help achieve better grounding resistance and performance.
