Re: size of fuse vs size of wire.............
This is Approx.: 18awg 14amps, 16awg 18amps, 14awg 20amps, 12awg 25amps, 10awg 30amps. This also varies according to wire type Insulation and such. A 20amp fuse should be fine for you fan. Does the fuse blown right away? Is the 20 amp fuse feeding the relay? The fan? Just some question that would help.
