Pole grading is based on which of the following factors?

• A. Importance of services
• B. Size
• C. Loading capabilities
• D. Strength

Answer: (C)

Pole grading is about the loads the pole must carry. It defines the allowable loads the pole can safely resist, including dead weight from conductors and hardware and live loads from wind, ice, and other conditions. By specifying a higher grade, you ensure the pole has enough stiffness and strength to handle bending, buckling, and lateral forces under expected conditions. Size or material strength alone isn’t what determines the grade—the grade is chosen to match the actual loading capabilities the installation will experience. The importance of the services being carried isn’t a mechanical criterion, since what matters is how much load the pole must support.
