I am stupid.
I have a 4 gauge wire that I want to hook to a mosfet in a 14vdc, 30 amp circuit. The leg on the mosfet is about the size of the wire in a 30 amp fuse. I look at these and have trouble believing that this is going to work. The 4 gauge wire gets warm with only 20 amps, it seems that if I reduce the size to connect to the mosfet it will overheat quickly. Am I concerned about nothing?
I use 4 gauge to prevent problems, is it causing a problem?
Thank you for any help.
