Description

The 8/2 UF-B Underground Feeder Cable is designed to deliver power from residential, commercial, and industrial buildings to outdoor installations. It is suitable for:

  • Direct burial without conduit

  • Sunlight exposure in outdoor settings

  • Feeder or branch circuits with proper overcurrent protection

With a 600-volt rating, it provides reliable performance in outdoor, underground, and wet environments.

UF-B General Applications

  • Underground feeding

  • Outdoor lighting systems

  • Outdoor outlets and receptacles

  • Direct burial installations

  • Wet or damp locations

  • Pump systems

  • HVAC unit wiring

  • Underground branch circuits

  • Indoor wiring in areas exposed to moisture

Specific Applications for 8/2 UF-B Wire

  • 240V Circuits Without Neutral: Common for devices like water heaters and baseboard heaters that require only two hot wires.

  • 120V Circuits: Used where longer distances necessitate thicker wire to prevent voltage drop, such as in outdoor or remote setups.

    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 8/2 and 8/3 UF-B wire?

    8/2 UF-B wire has two insulated conductors (black and white) and a ground wire, making it ideal for straightforward circuits like:

    • 120V circuits for outdoor lights or outlets
    • 240V circuits without a neutral (e.g., water heaters or smaller pumps)

    In comparison, 8/3 UF-B wire adds a red conductor, making it suitable for more complex applications such as 240V circuits with a neutral, subpanels, or well pumps with multiple loads. 8/2 UF-B wire is perfect for simpler setups, while 8/3 handles more demanding needs.

    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.
