Rated for in-wall installation, this cable carries power to wall outlets. Also known as branch circuit wire, it can be used without conduit. It has solid THHN building wires, so the cable will stay in the shape you bend it. The uninsulated ground wire is not counted in the number of wires.
UF-B cable is for wet locations where cable may be exposed to moisture or humidity. It's often used as underground feeder cable for pumps and lighting. The insulation resists moisture and UV light.
