FIRMERST 14/3 UF Wire Outdoor Direct Burial Underground Feeder 25/50/100ft

  
Simple Guide: How to install UF-B wire. Dig a trench at least 18 inches deep along the planned cable route. Connect UF-B cable to the main panel, route it via a drilled hole or outlet, cover exposed sections with conduit, and lay it in the trench.

At the opposite end, drill into the detached structure, enclose the exposed cable section in conduit, and connect it to the sub-panel. After verifying that all connections are secure, place warning tape above the UF-B cable in the trench, then backfill the trench.
