How is UF electric wire different from regular Romex® cable? How do I select the right wire?

UF (or Underground Feed) cable is necessary any time you’re laying cable underground. The wires in UF are individually insulated. They’re then wrapped together in more insulation for further protection from weather and sunlight. On the other hand, Romex® is wire coated in plastic and is only suitable for indoor use.
