American wire gauge (

**AWG**), also known as the Brown & Sharpe wire gauge,**is**a logarithmic stepped standardized wire gauge system used since 1857 predominantly in North America for the diameters of round, solid, nonferrous, electrically conducting wire.How gauge of wire is measured?

**Wire gauge**is a

**measurement**of

**wire**diameter. This determines the amount of electric current a

**wire**can safely carry, as well as its electrical resistance and weight.

## What does 24 AWG mean?

American Wire Gauge (

**AWG**) is a U.S. standard set of non-ferrous wire conductor sizes. The "gauge"**means**the diameter. Non-ferrous includes copper and also aluminum and other materials, but is most frequently applied to copper household electrical wiring and telephone wiring. Telephone wire is usually 22,**24**, or 26.3

## Is there a difference between AWG and gauge?

The confusion continues with all the ways

**AWG**can be abbreviated. For example, you or I might say or jot down that a conductor is “12**gauge**”. But, that can also be expressed**as**12**AWG**, #12, No. 12, No. 12**AWG**, or 12 ga. They all mean the**same thing**and are used interchangeably.4

## Is wire gauge measured with insulation?

Generally speaking, the smaller the

**gauge**number, the thicker the**cable**. This form of**measuring cable**thickness is used specifically for electrically conductive**wire**. Note that the diameter of the**cable**does not include the outer**insulation**- just the conducting**wire**on the inside.
