At what distance should grounding connections be from a foundation wall?

The correct distance for grounding connections from a foundation wall is 2 feet. This requirement is based on ensuring the effectiveness and safety of the grounding system. When grounding connections are placed too close to a foundation wall, the interaction between the grounding system and the building's structural components could be compromised. Maintaining a distance allows for proper grounding and minimizes potential hazards related to electrical faults.

This distance also helps to avoid interference from the building's concrete, which could affect the conductivity and effectiveness of the grounding system. By adhering to the recommended distance, you help ensure that the grounding electrodes function correctly and provide reliable protection against lightning strikes and electrical surges.
