Overhead Line Clearances
| Below are general clearance requirements for energized lines at 0-750 volts. This information should not be used if code standards are in question (contact the local code authority for specific information for your area). To get clearance information on lines energized above 750 volts contact the Cooperative.
There are three organizations that influence these general standards (in places where the standard varies, the strictest is shown here):
- BEC -- Bandera Electric Cooperative
- State -- State of Texas
- NESC -- National Electrical Safety Code
- NEC -- National Electric Code
