UF Cable. ”UF” stands for underground feeder; rated for in-ground and damp-area installation. Looks like NM-B cable but the wires are embedded as a group in solid thermoplastic (rather than individually encased in flexible thermoplastic).
What is the diameter of 12 2 UF wire?
A: It has outside diameter of 463 x 183 mil.
What is Type UF?
Description. Type UF-B (Underground Feeder and Branch-Circuit Cable) is generally used in underground, direct burial installations as branch circuits and/or feeders to outside floodlights, sewer pumps and motors, electric gates and other loads typically supplied from a distribution system.
What gauge is UF cable?
Sizes: 14 AWG – 6 AWG Number of Conductors: 2 or 3. 2. Ground Wire: Soft annealed uncoated copper solid wire per ASTM B3.
Can I use 12 gauge wire on a 15 amp circuit?
Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit.
Can you use 12 2 wire underground?
12/2 Solid CerroMax UF-B Cable can be used in applications that include outside lamp posts, pumps, and other loads outdoors, underground and in wet areas. It can also be used for outbuildings such as garages and barns.
What color is UF wire?
Type UF cable is usually gray and comes in rolls that look like standard non-metallic (NM) sheathed cable. While standard NM cable is rated only for dry, interior applications, UF cable can be used outdoors as well as indoors.
Can Type UF cable be used in commercial garages?
Type UF cable shall not be used as follows: (1) As service-entrance cable. (2) In commercial garages. (3) In theaters and similar locations.
Can I use UF cable above ground?
The use of UF cable on the exterior surface of buildings or structures is permitted by Sec. 225.10(18) and Sec. 334.10(3) of the NEC. If the cable is exposed to physical damage it must be protected in accordance with Sec.
How far can you run 12 2 wire on a 20 amp breaker?
After these distances, the circuit will go over the recommended 3% voltage drop. You can run a 12 gauge wire up to 70 feet on a 15 amp circuit. That number drops to 50 feet if you run 12 gauge wire on a 20 amp circuit.
What size wire do I need for 100 amp service?
Size Wire for 100 Amp Service
Wiring a 100 amp breaker panel requires either #4 copper wiring or #2 aluminum or copper-clad wiring. Which wire used is determined by the voltage drop and length of the wiring. Many licensed electricians use #2 copper-clad or aluminum wire size.
What is a 12 2 wire?
“12-2” means 12 gauge, two insulated current carrying wires, plus a bare ground. 12-2 wire usually has a black, white and bare ground wire. Sometimes the white is red instead for 220V circuits without neutral. In the latter case, the sheath is usually red too.
Can you run UF cable without conduit?
UF cable can be direct buried (without conduit) with a minimum of 24 inches of cover. Wiring buried inside rigid metal (RMC) or intermediate metal (IMC) conduit must have at least 6 inches of ground cover; wiring in PVC conduit must have at least 18 inches of cover.
Can you run UF cable overhead?
Section 340.12(11) does not permit UF cable to be used as overhead cable unless installed as a messenger-supported wiring installation. There is no messenger supporting this UF cable. The support fitting is attached directly to the non-metallic cable jacket.
Can UF cable be buried underground?
Underground feeder cables, labeled UF, can be buried without additional protection from conduits because they have a tough jacket designed for burial. Bury UF cables 24 inches below the soil surface, and 18 inches deep when protected by 2 inches of concrete.
