      FAQ's

      What is UF-B Wire?

      UF-B wire (Underground Feeder - Type B) is an electrical wire used for direct burial in the ground without needing additional conduit. It's water-resistant, sunlight-resistant, and suitable for outdoor and underground applications, particularly for powering outbuildings and exterior lighting.

      What is the difference between UF-B wire with or without ground?

      UF-B wire with ground is used for applications where additional safety is needed, such as when the wire is exposed to moisture. UF-B without ground can be used when local codes don't require grounding (f.e. lighting circuit where local code allows it).

      What is UF-B cable permitted for use?

      Article 340 of the NEC permits UF-B cable to be used for direct burial without the conduit. It also allows it for wet, damp, and corrosive locations. It can also be used above ground if UV-resistant and in conduit. UF-B is suitable for branch and feeder circuits for outbuilding and exterior applications.

      Can UF-B wire be used indoors?

      You can use UF-B indoors, but this is not a common practice. NEC does not ban UF-B indoors, but NM-B and THHN in conduit are more common interior cables that are easier to install.

      What is the difference between UF and UF-B Wire?

      UF-B is a modernized version of the UF cable with better moisture, corrosion, and sunlight resistance. Most of the underground feeder cables currently sold in stores are UF-B.

      Can UF-B be buried?

      The cable is designed to be buried. The standard burial depth is 24 inches.

      Can UF-B wire be put in conduit?

      It is possible to run UF-B through PVC or metal conduit for underground applications, but THWN is a preferable option as it is easier to install.

      Can UF-B wire be exposed?

      UF-B wire can be exposed if it is UV-resistant and not subject to physical damage.

      How to strip UF-B wire?
      • Turn off the power for safety.
      • Slice the gray outer jacket carefully without cutting the inner wires.
      • Peel back the jacket to expose the insulated wires.
      • Use wire strippers to remove the insulation from the ends of each wire, typically about 3/4 inch.
      • If there's a ground wire, strip it similarly if insulated.
