It is meant to be buried in a trench underground.
Homeowners rarely deal with USE cable themselves; it is handled by utility professionals.
The primary difference between standard NM and underground feeder (UF) cable is in the cable construction.

Standard NM cable contains wires that are wrapped with paper and a relatively loose plastic sheath.
UF cable has wires that are completely encased in solid plastic.
Tips for Installing Direct Burial Cable
The biggest concern with buried cable is digging.
Direct buried cable is governed by many building and electrical code rules to ensure safe installation.
Only professionals should handle these types of cables.
UF cable, on the other hand, can be DIY installed.
The lifespan of direct burial wire varies.
Aluminum and copper wiring may last between 80 and 100 years.
That being said, electrical wiring can crack or fray at any time due to other factors.
Depending on the utility, different types of electrical conduit materials are required.
Some applications require rigid material, but others require flexibility.
Specialty conduit material will be required if installed in a primarily wet environment or under highly corrosive conditions.
However, direct burial wire performs very well and is designed to withstand moisture.
