Type UF cable is defined as what kind of assembly?

Type UF (Underground Feeder) cable is specifically designed for direct burial applications, making it unique among electrical cables. It consists of multiple conductors that are insulated and jacketed in a way that allows them to be safely buried underground without requiring additional protection. This capability is crucial for applications such as feeding power to outdoor fixtures, landscape lighting, or supplying power to structures that are located away from buildings.

The construction of Type UF cable ensures it is robust enough to withstand moisture and the physical pressures that come from being buried. This factor is particularly important in preventing electrical faults and enhancing safety in outdoor environments.

In contrast, other types of cables might be suitable for different applications—like indoor use or within protected conduits—but they do not have the same direct-burial capabilities. Hence, recognizing UF cable as a factory assembly suitable for buried applications is key in understanding its primary use and purpose in electrical installations.
