What is the maximum sag allowed for a 100ft drop cable?

The maximum sag allowed for a 100ft drop cable is crucial in ensuring the cable's performance, safety, and longevity. A sag of 12 inches is considered standard for a cable of this length, as it prevents excessive tension and strain that could lead to damage or service interruption. Proper sag allows for natural expansion and contraction of the cable due to temperature changes, wind effects, or other external factors, thus maintaining the integrity of the installation.

Sag measurements are based on engineering principles that account for the weight of the cable, the distance between supports, and environmental conditions. Allowing a maximum sag of 12 inches strikes a balance between maintaining structural integrity and ensuring that the cable remains clear of potential obstructions below, such as walkways or vegetation.

While other options represent larger sags, these would likely be too excessive for a 100ft drop cable, potentially risking damage to the cable and infringing on safety protocols. Hence, the choice of 12 inches as the maximum sag is well within the recommended parameters for proper cable installation and maintenance.
