12/3 Solid Underground Feeder Cable UF-B Copper 600V

Excellent service

Ordered the wrong size wire by my mistake. Made one phone call and order was corrected by a helpful customer service per.

Great quality

Ran ~100 feet from the breaker panel to a RV 50amp receptacle. Direct buried in a trench. So far doing good. Fast on time delivery, fast response to questions. Will use NNC again for any future work/project.

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 12/3 UF-B Cable?

Multi-wire branch circuits that need both 120V and 240V
Outdoor HVAC units
Subpanel feeding
Large outdoor lighting systems
Outdoor pumps

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.
