What does NEC Article 300.5 specify?

NEC Article 300.5 specifically addresses the required burial depth of conductors. This provision outlines the minimum depth at which various types of underground conductors must be buried to ensure safety, protect against mechanical damage, and accommodate local conditions. The specified burial depths depend on factors like the type of conductor being used, whether it is conductors installed in raceways or direct burial types, and the environmental conditions they may be exposed to.

Understanding the requirements in Article 300.5 is essential for compliance with safety regulations regarding underground installations. Proper burial depth helps prevent accidental contact with the conductors, minimizes risks of damage from natural elements or disturbances, and is critical for the safe operation of electrical systems. Ensuring that conductors are buried at the depth specified by the NEC contributes to the longevity and reliability of electrical installations in various environments.
