What is the purpose of the exceptions listed in the sections for overhead service-drop conductors?

The purpose of the exceptions listed in the sections for overhead service-drop conductors is primarily to explain clearance requirements. These exceptions are critical because they provide specific guidelines on the minimum distances that overhead service drops must maintain from various structures, roads, and other physical features. This information is vital to ensure the safety and accessibility of overhead service drops, preventing potential hazards that could occur if these conductors are too close to people, buildings, or vehicles.

Understanding clearance requirements helps ensure that proper distances are maintained to protect both the service drop infrastructure and the general public. These standards are crucial for fostering safety in residential and commercial environments, minimizing the risk of electrical hazards or accidents. Thus, the exceptions serve to clarify important aspects of how overhead service drops should be installed and maintained in compliance with safety regulations.
