Building Cable

UF-B

Use For:
NM-B, THHN: Buildings
UF-B, THHN: Buildings, Outdoors
Bend and Stay
Temperature Range: 10° to 190° F
Insulation: PVC Plastic

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.

Water-Block Control Cable

Use For: Buildings, Outdoors
Flexible
Temperature Range: 0° to 220° F
Insulation:
Outer: Fiber; PVC Plastic
Inner: PVC Plastic

Keep water from damaging wires—this cable has a layer of absorbent material that traps moisture before it reaches the internal wires. Use it in washdown areas, indoor/outdoor transitions, and direct burial without conduit. It sends signal and data to operate, measure, or regulate automated equipment.
