What type of cable is categorized under Article 340?

The type of cable categorized under Article 340 is Type TC, which stands for Tray Cable. Article 340 of the National Electrical Code (NEC) addresses the specific requirements for tray cables, which are designed for use in cable trays. Tray cable can be used for various applications, including those that require flexibility and the ability to withstand exposure to moisture, sunlight, and certain chemicals.

Type TC cables are constructed to offer mechanical protection and flexibility, making them suitable for installation in locations where traditional cables may not be as effective. They can be used in industrial settings, as well as in installations that require a safe, reliable means of distributing electrical power and signals in a variety of environments.

In contrast, Type SE (Service Entrance cable) has its own specific requirements outlined in a different article (Article 230), which details its use for electrical service entrance to buildings. Type FMC (Flexible Metal Conduit) and Type MC (Metal Clad) also belong to their respective categories and articles, focusing on different applications in electrical installations. Therefore, understanding the classification of cables according to the NEC is essential for selecting the right type for specific applications.
