TIP : Wire Size for Electrical & Electronic Projects

WireWhen building electronic project it is very important to make sure you are using the correct size wire. Obviously you want to use a high-quality wire to begin with, but size does matter. I tried to find a single comprehensive chart that showed the correct size/gauge wire for different ampere ratings at different lengths. The lengths I wanted to see were those that I customarily use, or may use, in my projects. I couldn’t find a single chart that covered what I needed so I combined and merged several charts to meet my needs.

Here is the result of that work. I hope it proves useful to you while working on your projects,

Wire Gauge Chart, wires size ampere ratingThis is a very conservative chart showing examples of amps / wire gauge / length of wire. Your results may vary widely and you can get longer runs with smaller gauge wire carrying more amps. I wanted to err on the side of caution.
