At what height above finished grade shall direct-buried conductors and cables be protected?

Direct-buried conductors and cables must be protected when they are at a specified height above finished grade to ensure safety and prevent accidental contact that could lead to electrical hazards. The requirement for protecting these conductors at 8 feet aligns with industry standards that prioritize safe access and the mitigation of risks associated with overhead installations.

When conduits or cables are run near areas where people may be present, such as walkways, driveways, or other accessible locations, having a clearance of 8 feet helps to prevent accidental contact by individuals or vehicles. This height serves as a safety measure, as it allows for safe passage beneath these electrical installations without the risk of interference or accidental disconnection.

Additionally, this standard helps address practical considerations, such as maintenance activities and the potential for future structures or landscaping that could interfere with the conductors or cables if they were buried lower. Ensuring a consistent height of 8 feet fosters safer working and living environments where electrical systems are installed.
