When a clamp top insulator is used, what is needed at the point of attachment?

• A. Conductor and armor rod
• B. Conductor, neoprene pad, and armor rod
• C. Conductor, top tie, and armor rod
• D. Conductor, side tie, and armor rod

Answer: (A)

Clamp top insulators rely on a direct connection that both carries current and protects the conductor right at the clamp. The essential items at the attachment point are the conductor itself and an armor rod. The armor rod distributes the mechanical load and shields the conductor from the clamp’s edges, reducing wear and preventing insulation damage. Additional items like a neoprene pad, a top tie, or a side tie aren’t required for this configuration, since they’re used with other attachment methods or purposes. So the needed combination is simply the conductor and the armor rod.
