C. Strength
Where guys are used with poles or similar structures, capable of considerable deflection before failure, they shall be able to support the entire load, the pole below the point of guy attachments acting merely as a strut. Stranded wires shall be used when ultimate strength of the guy exceeds 1800 pounds. Anchor rods and their appurtenances shall meet the same strength requirements as the guy wire or strand.
