What does UF wire stand for?
underground feeder
UF Cable. ”UF” stands for underground feeder; rated for in-ground and damp-area installation.
What is the difference between UF and UF B 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.
What can 12 3 wire be used for?
ROMEX® 12/3 wire is used in buildings for circuits that use higher amperage than the standard 20 amps. Most people are not familiar with this type of wire because it is used to hook up heavy-draw appliances such as water heaters and central air conditioning.
How far can I run 12 gauge wire?
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 50 feet away?
For 100 AMP service, you’ll need a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire. Make sure to limit your voltage drop to 3% regardless of distance.
Can you 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.
How far can you run 12 gauge wire without a voltage drop?
As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3 percent voltage drop….For 240-volt circuits:
| 14 AWG | 100 feet |
|---|---|
| 12 AWG | 120 feet |
| 10 AWG | 128 feet |
| 8 AWG | 152 feet |
| 6 AWG | 188 feet |
How far can I run 12 gauge 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.
Can UF cable be run exposed?
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.
