What is the diameter of a 12 gauge wire?
The diameter of solid 12 AWG wire is approximately 0.0808 inches (2.053 mm), and 14 AWG is 0.0641 inches (1.628 mm). Therefore, 12 AWG wire is about 26% thicker and has 59% more cross-sectional area than 14 AWG wire.

How do you determine wire gauge size?
Multiply the wire's diameter by itself. To calculate the gauge of stranded wire, you'll need to double the diameter. So, if you've measured a wire's diameter to be 0.005 inches (0.127 mm), multiply this value by itself. The result will be 0.000025 in (0.000635 mm).

What are the sizes of wire?
Wire gauge refers to the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter. Common sizes include 16-, 14-, 12-, 10-, 8-, 6-, and 2-gauge wire.
How do I know if my wire is 12 or 14 gauge?
How do you tell if your old wiring is 12-gauge or 14-gauge? Here's a simple visual. Twelve gauge is about the thickness of a nickel, and 14-gauge is about the thickness of a dime. Also, look at the breaker for the circuit in question to see if it's a 15-amp or a 20-amp breaker.
What size is 12 gauge wire?
0.0808 inches12 AWG Wire Diameter (12 Gauge Wire In mm) 12 gauge wire is 2.053 mm thick. This is equal to 0.0808 inches. Because the diameter of 12 AWG wire is so close to 2 milimeter we also refer to it as a '2 mm wire'.

What is gauge wire?
What Are Wire Gauges? The gauge of a wire refers to its thickness. Each gauge is represented by a number, with smaller numbers representing thicker wire gauges and higher numbers signifying thinner wires.
What is AWG wire gauge?
American Wire Gauge (AWG) is a standard method of measuring and identifying cable thickness developed in the United States for electrically conductive wire. It is suitable for specifying gauges for round and solid conductive wires made from non-ferrous material.
How many feet per pound of wire?
Feet per pound refers to the number of feet of wire needed to reach one pound in weight. (e.g., AWG 4 wire requires 7.918 feet, while AWG 40 requires 34.364 feet.) Resistance (ohms per 1000 feet). A wire’s electrical resistance depends on its length and thickness. Longer wires provide greater resistance than shorter wires.
Why do electrical wires need to be thicker?
For example, electrical circuits with higher amperage ratings require thicker wires to accommodate the load without experiencing excessive heat buildup. Using wires that are too thin for the specified circuit amperage can result in wire failure or ignition.
What is the difference between AWG 40 and AWG 4 wire?
(e.g., At 25° C, AWG 4 wire has a resistance of .2485Ω for 1000 feet, while AWG 40 wire has a resistance of 1079Ω for 1000 feet.) Current capacity (amps).
The Exact Electrical Load and Temperature Rating are Important
Going back to the example I share above, if we simply bump the load to 125A, you’ll already need a 2/0 aluminum wire instead, which is obviously entirely different from the 125 amp wire size copper I mentioned. It’s also advised to increase your circuit breaker capacity to 175A if that’s the case to ensure safety.
Conclusion
To sum it up, always know the specifics beforehand. Take note of the electrical load, temperature rating, and, sometimes, even the distance required for the entire wiring if it’s necessary. This is the only way for you to know what size wire for 125 amp breaker.
How do you calculate wire size?
The size of an electrical wire means the cross-sectional area it has (and in turn its diameter). The larger the area, the more current the wire can transmit with lower resistance. It is pretty similar to water flowing in a pipe. Using a larger pipe allows more water to flow at a lower pressure.
Correcting for operating temperature
The resistivity of a conductor depends on its temperature, so the environment you will be installing your wire in will affect the wire size. When specifying a temperature, try to think of the maximum temperature the wire is likely to operate in, to be on the safe side.
Example of using this AC wire size calculator
Let's say that we are using an AC single-phase system operating at 120 V; a 3% allowable voltage drop; a copper conductor; 25 A peak current; a one-way cable run of 100 m (328 ft); and 50 °C max operating temperature.
