Drop wires impose transverse loads if the departure angle is

Departure angle is the angle the drop wire takes as it leaves the pole toward the building. The wire’s tension has a horizontal component that pushes on the pole—the transverse load. When the departure angle is 45 degrees or less, a notable portion of the tension acts sideways, making the transverse load on the pole significant enough to require consideration in the design. If the angle is steeper than 45 degrees, the path is closer to vertical, reducing the sideways component and the associated transverse loading. That’s why this threshold is used: small to moderate departure angles meaningfully contribute to transverse loading on the pole.
