What Is the Standard Height of Power Lines?

Answer

The standard, minimum and maximum height of power lines depends on how much voltage they will carry and the area's traffic. Areas where vehicles travel will need more clearance. Lines of 300 volts have to be at least 12'. Over 300 volts needs a minimum of 15'. Areas with vehicular traffic needs an 18' minimum height.
