The AWG system is designed to indicate and categorize the stranded or solid wire and cable based on their sizes.
different sizes of wire and cable have unique properties so their uses and applications may vary from one size to another size.
awg stranded wire
In each building, you must install wires and cables to meet electrical needs.
You need to make sure to choose high quality wires for a safe electrical connection.
You can choose cables based on different criteria.
One of them is wire gauge, also known as gauge.
Different cables serve different purposes.

What is a wire gauge?
The thickness of the wire refers to the thickness of the wire.
A number represents one meter.
The higher the number, the thinner the line.
The industry uses the American Wire Gauge method to measure the thickness of electrical wires.
The AWG method is a standard method developed in the USA.
Using this method, you can specify gauges for solid, non-ferrous and round conductive wires.
AWG formula specification
According to the American Wire Gauge (AWG) method, the maximum wire gauge is No. 36 AWG, minimum gauge No. 0000.
These are 0.005" and 0.46" in diameter respectively.
There are 40 gauges, or you could say 39 steps, between these maximum and minimum sizes.
The ratio between these two diameters is 1.92.
Now, as the number of gauges decreases, the cross-sectional area increases.
As a result, the diameter increases as the meter number decreases.
Now suppose that A and B are two consecutive gauges whose diameters are diameter A and diameter B.
So for both the diameter ratio is 1.12293. Conversely, the percent diameter of a gauge two steps apart is (1.12293) ² ≈ 1.26098.
The relationship between thread gauge and other technical specifications The thickness of the wire affects its electrical performance.
Therefore, with the help of thread measuring instruments, the industry can determine whether the thread is suitable for its application.
Diameter: The wire gauge can vary from low to high.
A decimal number represents a large diameter and a large number represents a small diameter.
For example, AWG 4 has a larger diameter than AWG 40.
When the Gauge is reduced by six levels, the wire diameter doubles, meaning that the diameter of a four-gauge wire will be twice that of a tenth-gauge wire.
Area: You can calculate the cross-sectional area of a wire using the formula A= πr2.
Here r is the radius (half diameter) of the wire.
When the meter drops three levels, the cross-sectional area doubles.
Foot per Pounds: This means how many feet of thread you need to reach one pound.
