What is the required distance from a tower for the ground ring?

• A. 2 feet
• B. 4 feet
• C. 6 feet
• D. 8 feet

Answer: (A)

Grounding effectiveness hinges on creating a continuous, low-impedance path to earth right around the tower. The ground ring is placed close to the base so it can bond with the tower’s grounding electrode and the equipment grounding conductor without being in the way of the foundation or tower hardware. A distance of two feet from the tower keeps the ring tight enough to form a solid grounding loop while avoiding interference with the footing or rebar. If it were placed farther away, the grounding path becomes more spread out, increasing impedance and reducing bonding effectiveness. If it were too close, it could interfere with the foundation work. So, two feet is the appropriate distance.
