Wire with a gauge of 12 American copper Wire Gauge (AWG) is frequently used in electrical engineering. Amplifying at 25A at a temperature of 75 degrees Celsius on average,
12 Gauge Copper Wire
In the calculation of car wire size, the application and use of wire shall be considered.
The National Electrical Code specifies wire size requirements to prevent overheating, fire, and other hazardous situations. Properly sizing wiring for many different applications can become complicated and overwhelming.
Amperage is a measure of the current flowing through a circuit. The ampacity rating of the wire determines how much amperage the wire can safely handle. In order to correctly size the wire for your application, it is important to know the ampacity rating of the wire.
However, many different external factors, such as ambient temperature and conductor insulation, play a role in determining the current-carrying capacity of a wire.
12 Gauge Copper Wire Features
Conductor ampacity is calculated by not exceeding a specific temperature rise under a specified electrical load. The heating of the conductors is directly attributable to the I2R losses in the circuit.
The length of a conductor is proportional to its resistance. However, the cross-sectional area of the conductor can also be changed to change the resistance of the conductor.
By increasing the cross-section of the conductor (or increasing the size of the wire), the resistance decreases, allowing the current-carrying capacity to increase.
Good judgment should be used when sizing conductors, as large conductors can be expensive and difficult to install, while small conductors can be potentially dangerous.
Use the calculator above to size wires for basic applications, or check out some wire ampacity charts for wire ampacity values.

As a general rule, the smaller the diameter of the wire, the higher the resistance and therefore the lower the current capacity over a given length. It is almost always possible to use larger thread. If in doubt about the load, please use the table.
In addition to length, other factors can affect the capacity of the wire, including whether it is in a hot environment, the duration of the load, stranded versus solid wire, wire coating, etc.
