What does Article 338 refer to regarding cables?

Article 338 of the National Electrical Code (NEC) specifically governs the requirements and guidelines for the use of Type UF (Underground Feeder) cables. Type UF cables are designed for direct burial in the ground or for use in wet and dry locations above ground. The article outlines the construction specifications, installation methods, and permissible applications of this type of cable, ensuring that it adheres to safety standards and is suitable for its intended use.

Type UF cables have characteristics that make them reliable for various electrical installations, particularly in outdoor or damp environments. They often have insulation that protects them against moisture and the elements, contributing to the overall safety and longevity of electrical systems installed with this type of wiring. Understanding the specifics laid out in Article 338 is crucial for electricians to ensure compliance with code requirements and to guarantee the safety and efficacy of their electrical installations.
