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.
