What is the breaking strength of a class 5 pole?

Breaking strength is the maximum load a pole can withstand before it fails. For Class 5 poles, the standard rating is about 8.4 kN, which is approximately 1900 pounds-force (about 8452 N). This value comes from established tables used in pole design, and it provides the raw limit that engineers use when checking loads from winds, ice, and other forces. In practice, the working or allowable load is much lower than this breaking strength because a safety margin is applied. So the value around 8.4 kN / 1900 lbf is the correct reference for a Class 5 pole.
