What type of cable is categorized as Type TC?

Type TC cable, or Tray Cable, is designed specifically for power and control applications. This type of cable is commonly used in environments where it will be installed in trays, providing flexibility and ease of installation in both indoor and outdoor settings. Type TC cables are constructed to withstand sun exposure and moisture, making them suitable for a variety of applications, including both industrial and commercial installations.

The reason this choice is correct lies in the specific applications and construction features of Type TC cable. It typically contains conductors that may be metal or wire insulation, and it is available in various configurations to accommodate different voltage levels and environments, which is essential for power and control systems.

The other options refer to different types of cables with distinct applications. Service-Entrance Cable is primarily meant for bringing power from the utility company to the home or building. Underground Feeder Cable is specifically designed for underground installations, providing power to outdoor structures or equipment, and Nonmetallic-Sheathed Cable is mainly used for residential wiring within walls and ceilings, emphasizing its lack of protective sheathing found in Type TC. Each of these types has its unique specifications and applications, differentiating them from Type TC's role in power and control tray installations.
