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.
Why is the vinyl jacket so hard to strip off?
UF-B cable is designed for direct burial and outdoor use, so the outer PVC jacket is intentionally thicker and tougher than indoor NM-B wire. This added protection improves resistance to moisture, abrasion, and soil pressure.
Is the jacket thick enough to cover and protect the ground wire?
Yes. The jacket is 0.90 mm thick, fully covers the ground wire during installation. Our jacket thickness falls within industry standards and is optimized for durability and code-compliant underground installation.
Is this cable suitable for direct burial without conduit?
Yes. This is UF-B (Underground Feeder) cable, rated for direct burial and outdoor use without conduit
Can this wire be used outdoors in wet or damp locations?
Absolutely. The cable is designed to withstand moisture, sunlight exposure, and soil contact, making it ideal for outdoor lighting, pumps, sheds, garages, and yard installations.
