amperage for 12 gauge wire
People also ask
How many amps does a 12-gauge wire carry?
Electrical current is measured in ampacity, and each wire gauge has a maximum safe carrying capacity. For standard non-metallic (NM) cable, these amperage capacities are: 14-gauge wire: 15 amps. 12-gauge wire: 20 amps. 10-gauge wire: 30 amps. 8-gauge wire: 40 amps. 6-gauge wire: 55 amps. 4-gauge wire: 70 amps.
What is 12 gauge wire used for?
12 gauge wire is one of the most useful AWG wires. You can find it pretty much in every home, and in most cars. It鈥檚 sometimes referred to as the 2 millimeter wire because the diameter of a 12 gauge wire is 2.053 mm; if you round that up, it鈥檚 about 2 mm. If you express the cross-section of a 12 gauge wire in mm2, you get 3.31 mm2.
What is the electrical resistance of a 12 gauge copper wire?
Electrical resistance is measured in Ohms (惟). Resistance of 12 AWG copper wire is 5.211 milliohms per meter (m惟/m). This translates to 1.588 milliohms per foot (m惟/ft). As far as resistance is concerned, copper wires are about 40% more efficient for transporting electricity than aluminum wires.
What are the different gauge wires?
We鈥檙e going to simplify every wire鈥檚 characteristics (mm, mm2, amps) 鈥?from AWG 4/0 to AWG 40 gauge wire 鈥?in a systematic and concise easy-to-understand way. Example: Diameters (in mm) for AWG wires from 10 gauge wire to 28 gauge wire. This overview article about AWG gauge wires will give you all the info you need about wire sizing.
