What are the minimum clearances required for overhead conductors according to the NEC?

The minimum clearances for overhead conductors, as specified by the National Electrical Code (NEC), are based on the voltage of the conductors and include specific vertical and horizontal distances. The NEC sets these clearances to ensure safety and reduce the risk of electrical hazards.

For conductors carrying a voltage of 0-750 volts, the typical minimum clearance from the ground is at least 18 feet, particularly when located over streets or driveways where vehicles may pass underneath. Additionally, proper horizontal separation from structures is also outlined in the NEC, emphasizing the need for adequate space to avoid contact with buildings, trees, or other structures that might interfere with safe operation.

Choosing this answer reflects an understanding of how the NEC categorizes clearances based on voltage levels and acknowledges the need for adherence to those standards to ensure public safety and compliance with electrical installation practices.
