In most cases, the line wires can be relied on to hold the pole in conformity with the line direction, while guys or pike poles are required to hold it in the other directions.

(2) Service-drop conductors. Free service-drop conductors; do not count on them to hold a pole because any strain might pull the service-drop brackets off the buildings.

(3) Energized replacement. If a pole must be replaced with conductors energized, the wire must be properly covered with rubber protective equipment designed for this purpose, so work on the pole can be done safely as covered in section XV

b. Pole setting. Poles need to be set in accordance with ground conditions. For normal firm ground,

minimum pole-setting depths are given in table 4-2. In other types of soil, pole-setting depths need to be increased or decreased, in accordance with the local utility's practice, dependent upon whether the ground tends to be swampy or rocky.
