What is the minimum distance above grade that direct-buried conductors and cables must generally be protected?

The minimum distance above grade that direct-buried conductors and cables must be protected is eight feet. This requirement is established to ensure safety and reduce the risk of accidental contact with the conductors or cables. Maintaining this height helps to prevent electrical hazards due to the conductors being accessible to individuals or equipment at ground level.

In practice, this standard is crucial for areas where people or machinery might be present, as it minimizes the risk of unintentional interference with the electrical systems. Additionally, keeping conductors at this height prepares for potential flooding or excavation activities where the buried conductors could be exposed. Thus, adhering to the eight-foot requirement is essential in fostering safe operating conditions around installed electric infrastructure.
