What size is a zero gauge?
What size is in between 0 and 00? When you get to 0g, the next size is 00g (pronounced “double zero gauge”). 00g is equal to about 3/8 of an inch. After 00g, we run out of gauge sizes, so we use fractions of an inch instead. The next size after 00g is 7/16″.

AWG Formulas
- According to the AmericanWire 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. The ratio of these two diameters is 1.92. Now, as the gauge...
Relationships Between Wire Gauge and Other Technical Specifications
- The wire’s thickness affects its electrical properties. Thus, with the help of a wire’s Gauge, industries identify whether a wire is suitable for their application or not. Diameter: Wire gauges may vary from lower to higher numbers. A small number means a large diameter, while a large number refers to a small diameter. For example, the diameter of AWG 4 is larger than the diamet…
Wire Gauge Size Chart
- The American Society for testing and materials (ASTM) maintains the standardization of wire diameters and cross-sectional areas. To see the latest wire gauge chart, you can see ASTM B258-18.
Stranded Wire AWG Sizes
- You can also use AWG gauges to describe stranded wire. For a stranded wire, the AWG gauge is the sum of the cross-sectional areas of each strand. Here, you do not count the gap between each strand. If the stranded wire is made of circular strands, holes consist of 25% of the wire area. Thus, the diameter of the overall bundle is 13% more than an equal gauge solid wire. To specify …
Typical Applications of Standard Wire Gauges
- The wire with different gauges has different electrical properties, and as a result, they are suitable for their unique applications. Higher gauge wires are fit for lighter-duty electric works. On the other hand, lower gauge wires are suitable for heavy-duty projects. For construction and building projects, the standard wire gauges used are 10, 12, and 14. Some other applications of the wire…
Choosing The Perfect Wire Gauge
- To choose the perfect gauge wire for your application, you must consider the carrying capacity and the current in amps that the wire needs to conduct. The current you need to run through a wire is directly related to the wire gauge. Further, the distance of the wire that you need also affects the wire gauge. As there is no perfect conductor, you lose voltage with distance due to h…
Conclusion
- For an electrical system to run in the desired manner, it is essential to pick the correct wire. As a rule of thumb, the Gauge is a crucial factor. However, determining the right wire size is a bit complicated. You may take the help of professionals. You can contact Cloom for any assistance with wiring harnesses and cable assemblies.
