On a piece of Romex wire, what does UF stand for?

Underwater Facility
Unshielded Fiber
Underground Feeder
Ultra-flexible

The correct answer is: Underground Feeder

The designation "UF" on a piece of Romex wire stands for Underground Feeder. This type of cable is specifically designed for underground installation and is rated for direct burial in the ground, which differentiates it from other types of electrical wiring. Underground Feeder wire is built to withstand water exposure and has insulation that is suitable for harsh environments, making it ideal for outdoor use, such as supplying power to outdoor lighting or other structures. The term "underground feeder" reflects its intended application in providing electrical power where it is necessary to run cables below the surface. This is especially important for preventing damage and ensuring safety in installations that may be exposed to moisture or other environmental factors. Understanding the correct terminology used for different types of cables is crucial for home inspectors, as it helps in evaluating the wiring systems present in homes and ensuring that they are appropriate for their applications.
