12 Gauge Wire Measurements

12-gauge wire is often referred to as 12 AWG wire, which stands for “American Wire Gauge”. The gauge defines the size of the wire in terms of its thickness, or diameter. 12 AWG wire has a diameter of 2.05mm (0.0808 inches).

Our 12 gauge wire spools come in a range of lengths, between 25 and 5000 feet. Additionally, we offer wire services enabling you to request custom wire lengths. You can learn more about 12 AWG wire specifications using our hook up wire resources table.

12 AWG Wire Applications

Our 12 gauge wire is used for a variety of common electrical applications, including wiring of appliances, outlets, and control panels. If a smaller circuit (requiring <20 amps) needs wiring, it’s an excellent choice. If you do require more than 20 amps, take a look at our range of hook up wire from 14-24 AWG.

Request Wire Customizations

In addition to cutting wire to custom lengths, we also offer wire repackaging, stripping, and twisting services, to make sure your 12 gauge wire spool best meets your needs. Contact us for wire processing services today.
