Hi,
I have a quick question about wire gauges and what is a safe amount of current to run through each gauge.
With my project, I should never see more than 20 amps of current, so I'd like to pick a gauge that will work well for 20 amps for current ( though I plan to operate below 20 amps).
I found this chart:

And according to this I would need an 8 gauge wire which I think is bigger than what I need?
My motor that I have that is rated for 18.5 amps of current and has 14 AWG, which according to this chart, should not support that big of a current.
So I am a bit confused here. What is a good AWG for a max current load of 20 amps (the smaller/cost effective the better).
Also, with regards to PWM (for speed controllers), all those really do is limit the amount of current flow through the PWM and by limiting that, we can control the motors speed because we can control how much current the motor sees, right?
Thanks,
-James
