Where Can You Install Type UF Cable?

Published in Electrical Wiring Locations 2 mins read

Type UF cable, specifically UF-B, is designed for underground installations, serving as an underground feeder cable to power outdoor equipment and structures.

According to the reference, UF-B cable is typically used as an underground feeder cable to distribute power from an existing building to outdoor lighting fixtures, pumps, outbuildings and other outdoor equipment. The cable can also be used as direct burial cable.

Here are the primary locations and uses where you can install type UF cable:

  • Underground Feeder: It is commonly run underground from a main building to supply power to separate structures or devices outdoors.
  • Direct Burial: One of its key features is that it can be buried directly in the ground without needing conduit, although local codes and specific installation requirements should always be checked.
  • Connecting to Outdoor Equipment: Use it to provide electrical power for:
    • Outdoor lighting fixtures: illuminating landscapes, pathways, or security areas.
    • Pumps: powering well pumps, pond pumps, or irrigation systems.
    • Outbuildings: supplying electricity to detached garages, sheds, workshops, or guest houses.
    • Other outdoor equipment: including fountains, hot tubs, or other fixed outdoor electrical loads.

Summary of Installation Locations:

Location Type Specific Examples Notes
Underground Feeders From building to outdoor destinations Supplies power to separate points.
Direct Burial In the ground (check local codes) No conduit required for burial.
Connecting Equipment Outdoor Lighting, Pumps, Outbuildings Powers specific outdoor electrical loads.

While primarily an underground cable, UF cable is also listed for use indoors under specific conditions, such as in corrosive environments or when protected against physical damage. However, its main application is outdoor and underground power distribution.
