Final answer:
The minimum height for a vertical overhead clearance for a service drop conductors over residential property and driveways with garage, not subject to truck traffic where the voltage does not exceed 300V, is typically 10 feet (3 meters) according to the National Electrical Code (NEC).
Step-by-step explanation:
The minimum height for a vertical overhead clearance for a service drop conductors over residential property and driveways with garage, not subject to truck traffic where the voltage does not exceed 300V, is typically 10 feet (3 meters) according to the National Electrical Code (NEC). This clearance is necessary to ensure the safety of individuals and vehicles passing underneath the conductors. It helps prevent accidents and the risk of electrical shock.
For example, if there are power lines crossing over a driveway or a residential property, the conductors need to be positioned at least 10 feet above the ground or any structures in order to provide sufficient vertical clearance.
