Service drops should not pass closer than how many feet over the ridge of a conventionally pitched roof?

Service drops should not pass closer than 3 feet over the ridge of a conventionally pitched roof to ensure safety and compliance with electrical codes. This clearance is critical because it minimizes the risk of electrical hazards, such as unintended contact with the electrical service lines during maintenance or when the roof is being serviced. Additionally, the regulation helps to prevent potential damage from tools or equipment that could inadvertently strike the service drop.

By adhering to this minimum height requirement, the likelihood of electrical arcing, which can occur if lines are too close to other objects, is significantly reduced. Furthermore, this guideline protects household occupants and any individuals performing work on the roof, promoting overall safety in residential electrical installations.
