2/0 AWG to mm2: Understanding Wire Sizes
When working with electrical wiring, understanding wire sizes is crucial to ensure safety and efficiency. One of the most common wire sizes used in electrical applications is 2/0 AWG (American Wire Gauge). But what does this mean, and how does it translate to other measurement systems, such as mm2 (square millimeters)? In this article, we'll explore the conversion between 2/0 AWG and mm2, and provide a comprehensive guide to wire sizes.
What is AWG?
AWG, or American Wire Gauge, is a standardized system used to measure the diameter of electrical wires. The AWG system is based on a logarithmic scale, with smaller numbers indicating larger wire diameters. The most common wire sizes range from 0000 (also known as 4/0) to 40 AWG.
What is 2/0 AWG?
2/0 AWG is a wire size that falls between 0000 (4/0) and 0 AWG. It has a diameter of approximately 0.115 inches (2.92 mm) and a cross-sectional area of about 67.4 mm2. 2/0 AWG wires are commonly used in high-voltage applications, such as electrical power distribution systems, transmission lines, and electrical substations.
Converting 2/0 AWG to mm2
To convert 2/0 AWG to mm2, we need to calculate the cross-sectional area of the wire. As mentioned earlier, the cross-sectional area of 2/0 AWG is approximately 67.4 mm2. This means that 2/0 AWG is equivalent to 67.4 mm2.
Wire Size Chart: AWG to mm2
Here is a wire size chart that shows the conversion between AWG and mm2:
| AWG | mm2 |
|---|---|
| 0000 (4/0) | 107 mm2 |
| 000 (3/0) | 85.0 mm2 |
| 00 (2/0) | 67.4 mm2 |
| 0 | 53.5 mm2 |
| 1 | 42.4 mm2 |
| 2 | 33.6 mm2 |
| ... | ... |
Conclusion
Understanding wire sizes is crucial in electrical wiring applications. Converting between AWG and mm2 can be confusing, but with this guide, you should now have a better understanding of how to convert 2/0 AWG to mm2. Remember that 2/0 AWG is equivalent to 67.4 mm2, and use the wire size chart above to convert other AWG sizes to mm2.
