What is the minimum required depth for an underground service?

The minimum required depth for an underground service is 30 inches. This depth is established to protect the underground cables from potential damage caused by heavy equipment, natural elements, or other digging activities that could occur at or near the surface. The depth ensures that the service lines are adequately buried to minimize the risk of accidental contact and to comply with safety codes.

Regulatory bodies like the National Electrical Code (NEC) specify these depths to ensure both safety and functionality of the electrical system. Maintaining the correct burial depth is crucial for preventing electrical hazards and ensuring reliable service over time. Understanding these requirements is essential for linemen and those working with underground electrical systems to safeguard both the infrastructure and public safety.
