what is a wire gauge
People also ask
What does gauge mean in electrical wiring?
The gauge also determines the resistance of the wire and its weight per unit of length. When dealing with wire gauge, the characteristics of a wire usually specified on a chart is the wire’s size (specified in AWG), diameter, area, feet per pound, ohms per 1000ft, and current capacity (in amps). Below is a chart of different wire gauges.
How many gauges of wire are there?
According to the American Wire Gauge (AWG) method, the highest Gauge of a wire is Nr. 36 AWG, and the smallest Gauge is Nr. 0000. The diameters of these two are 0.005 inches and 0.46 inches, respectively. There are 40 gauges between these largest and smallest sizes, or you can say 39 steps.
What is a circular wire gauge?
These wire gauges are available in a circular or oblong shape and it is having notches along the edges of the shape (as shown in below picture) and each notch is stamped with wire size number. This wire gauge can also be used to find out the thickness of sheet metal as well.
What does AWG stand for in wire gauge?
AWG stands for American Wire Gauge. The sizes 4-40 are standardized to this system and represent the diameter and area shown on the chart. The diagram above does not represent the exact size, but just a general diagram to show the approximate sizes of the type of gauges in reference to each other.
