Which is a proper grounding method for a tower?

Answer: D. Separate eight-foot ground rods for each tower leg, bonded to the tower and each other

A proper tower ground uses separate eight-foot ground rods for each tower leg, bonded to the tower and each other. This gives lightning many good paths into the earth. One short rod is not enough, and a cold-water pipe is not a proper lightning ground.

Tip: Eight-foot rod per leg, all bonded.
