What is the minimum spacing required between multiple ground rods?

The minimum spacing required between multiple ground rods is 6 feet. This spacing is essential to ensure that each ground rod operates effectively and does not interfere with the others. When ground rods are installed too close together, their ability to dissipate electrical currents into the ground can be compromised, potentially reducing the overall effectiveness of the grounding system.

This distance allows for adequate soil resistance to be achieved around each rod, enhancing safety and functionality. The National Electrical Code (NEC) stipulates this requirement to ensure that grounding systems provide reliable performance in safeguarding electrical installations against faults and lightning strikes. By adhering to this spacing guideline, electricians can ensure that their grounding systems meet established safety standards and provide optimal performance.
