In the 1st Chapter, we focus on the wire gauge chart, denoting diameter (mm), cross-section (mm2), and amperage (maximum allowed amps) for each AWG wire. The key part is that we cover each wire individually; from the big 4/0 – 1/0 wires to the most popular 12 gauge, 14 gauge...
You no longer need calculators, resources, or tables scattered around the internet. Here is the THHN wire size chart you need. You’ll easily see the values and load the different options can handle, including ambient temperatures. Fining out ampacities is no longer hard for your power cable!
This chart tells you what gauge wire you have to use for a 12V circuit that requires certain amount of amps at a certain distance. The easiest to explain this is just to look at the 12-volt wire size chart here: 12V Wire Size Chart ...

For example, let’s calculate the wire size of a 100-meter-long copper wire for a single-phase circuit when it must supply 30 amps of current with a 10 V voltage drop allowed: A(mm²) = 2× 1.7241×10-8 Ω·m × 100 m × 30 A / 10 V× 1,000,000 A(mm²) = 10.344...
