14 AWG wire has a normal load rating of 20 amps. 12 AWG has a rating of
25 amps. Since you are fusing the circuit at 20 amps, you want to
ensure that the fuse blows before the wire gets hot. Therefore, you
need to use at least 12 AWG. 10 AWG is also ok. In this case, I would
err on the side of overkill.

Subject: what gauge wire?
Hello everyone,
I'm still working on my electric fan conversion, and had a quick
question.
The gauge of the main power lead that will come off of the battery or
starter is what I've heard a variety of answers to.
My fan draws around 9 amps. I've been told to run a 10 ga. red wire,
while
others say 14 ga. is fine.
I'm running this through an inline fuse and was going to use a 20 amp
fuse,
but is that too much?
Opinions?
Thanks,
R. Ashford Little II
