How Big of a Wire for a Car Air Compressor260

When choosing a wire for a car air compressor, there are a few things you need to consider. The most important factor is the amperage draw of the compressor. This will determine the size of the wire you need to use. The amperage draw of a compressor is typically listed on the compressor itself or in the owner's manual. Once you know the amperage draw, you can use the following chart to determine the size of the wire you need.


Amperage Draw
Wire Size


0-10 amps
14 AWG


11-20 amps
12 AWG


21-30 amps
10 AWG


31-40 amps
8 AWG


41-50 amps
6 AWG

In addition to the amperage draw, you also need to consider the length of the wire you will be using. The longer the wire, the thicker it will need to be. This is because the resistance of a wire increases with its length. The resistance of a wire is measured in ohms. The higher the resistance, the more voltage will be lost over the length of the wire. This can cause the compressor to run less efficiently or even overheat.

To determine the correct wire size for the length of wire you will be using, you can use the following formula:```
Wire Size = Amperage Draw x Length of Wire / Voltage Drop
```

For example, if you have a compressor that draws 20 amps and you will be using 10 feet of wire, you would need to use a 12 AWG wire. This is because:```
Wire Size = 20 amps x 10 feet / 12 volts = 12 AWG
```

It is always better to err on the side of caution and use a thicker wire than necessary. This will help to ensure that your compressor runs efficiently and safely.

Here are some additional tips for choosing a wire for a car air compressor:
Use stranded wire, not solid wire. Stranded wire is more flexible and less likely to break.
Use copper wire, not aluminum wire. Copper wire has a lower resistance than aluminum wire, which means it will lose less voltage over the length of the wire.
Use a wire that is rated for the voltage of your compressor. Most car air compressors operate on 12 volts.
Be sure to connect the wire to the compressor and the power source securely. A loose connection can cause the compressor to run inefficiently or even overheat.

By following these tips, you can choose the right wire for your car air compressor and ensure that it runs safely and efficiently.
