Multiple conductor UF-B cable may be used for interior branch-circuit wiring in residential buildings at conductor temperatures not to exceed 90°C with an ampacity limited to that for 60°C conductors as specified by 340.10(4) in the NEC. The voltage rating for UF-B cable is 600 volts.
What is UF wire?
UF cable has wires that are completely encased in solid plastic. This encasement protects each wire from the others and does not allow moisture or other external elements to travel inside the cable. UF cable is also sunlight-resistant and allowed to be used outside and above-ground, where UV light will be present.Can you run UF cable in conduit?

Can UF WIRE be embedded in concrete?
Installing Buried UF Electrical Cable Underground Feeder, UF cable, cannot be run inside concrete.
Is UF wire sunlight resistant?
Type UF wire is sunlight resistant and rated for direct burial installation. Like Type NM it must be protected from physical injury. If you wanted to install a 120V weather proof convenience outlet in your yard, you might install UF wire in a trench (18 – 24″ deep).
What is the difference between UF and UF-B wire?
UF-B vs. UF-B cables are often confused with UF cable, another type of underground feeder electrical wire. … The regular UF cable is well-suited only to be buried in conduit. The difference between them is UF-B construction indicates a better resistance to water and corrosion, as well as a superior temperature range.
Can I use outdoor wire inside?
While the electrical wire meant for outdoor use can be used indoors, it would be dangerous to use indoor wires outside. Indoor wire is designed for use within the house and is not prepared to handle the external factors found outdoor such as temperature, moisture and even chemicals in some cases.
How long does UF cable last?
RE: Life expectancy of underground wire Should easily be 50 years.
Can you run nm Cable in PVC conduit?

What is code for underground conduit?
Low-voltage (no more than 30 volts) wiring must be buried at least 6 inches deep. Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.
What is the difference between SEU and SER cables?
Basically, SER is a round service electrical cable that typically has up to four conductors and a bare neutral. The cable is designed to use above the ground in feeder panels and branch circuits. SEU is an unarmored Style U flat service electrical cable with two-phase conductors and a concentric neutral.
Does service entrance cable need to be in conduit?
(1) Service-Entrance Cables. So, you’ll either need to have this service-entrance re-run with a conduit, or see if you can get your local electrical inspectors to sign off on using bollards (i.e. concrete-filled metal poles) to protect the meter pan and service cabling as Machavity suggests.
