What is the minimum spacing required between multiple ground rods during installation?

The minimum spacing required between multiple ground rods during installation is 10 feet. This requirement is important in ensuring that the grounding system works effectively. Proper spacing helps to reduce the potential for interference between the rods, as well as ensuring that they can each dissipate electrical current into the ground effectively without impacting each other.

When ground rods are too close together, their individual effectiveness can be compromised, and this can lead to higher resistance in the grounding system, which may not provide adequate protection against electrical faults. By maintaining a spacing of at least 10 feet, electrical integrity and safety are upheld, which is essential for the overall reliability of electrical systems.

The other spacing options provided do not align with the standard guidelines in electrical installation practices for ground rods. While larger spaces could theoretically provide additional benefits, the minimum requirement is established to balance effectiveness and practicality in real-world applications.
