Hi all, I am installing a fantastic vent fan on my first build. It has 16 awg wire. from my fuse box I used 14 awg wire and connected them with a butt connector. The fuse box is connected to a 12 v battery and I had a 7 amp fuse for the fan as its only load at that terminal. Problem was the fan didn't work. It only worked once I swapped out the 7amp fuse for a 15 amp fuse. I know the draw is only 4.5 amps on the fan.
I switched out the wire from the fuse box to the fan again using 14 awg and again the fan only ran with the 15 amp fuse installed. I didn't have a 10 amp fuse or I would have tried it.
What do you think is going on? Is this typical?
Many thanks in advance!
