  • Ul Standard 493 for Thermoplastic-Insulated Underground Feeder and Branch Circuit Cables
  • For use in interior wiring in wet, dry or corrosive locations under recognized wiring methods of the National Electrical Code (NEC)
  • Acceptable to be installed as a Non-Metallic Sheathed Cable following NEC Article 339-3 (4)
  • Acceptable for use per NEC Articles 300-4(b) and 339
  • ASTM - B3 and B-8
  • UL Standard 83
  • Federal Specification A-A-59544
  • RoHS/ REACH

Construction:

Conductor:

UF-B wire has solid or stranded Type THHN/THWN that are laid parallel with an uninsulated grounding conductor. The conductors are made of stranded annealed bare copper.

Insulation:

The cable is insulated with a PVC jacket with a nylon covering. It is resistant to moisture, grease, corrosion, sunlight, and chemicals.

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 are the particular applications of 6/3 UF-B Cable?

6/3 UF-B wire with ground feeds power to large appliances and subpanels.

The applications include:

  • Feeding sub-panels
  • Large outdoor installations
  • Outdoor lighting systems
  • Power supply to outbuildings
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.
