Fusing to the size of the wire....
I know that you're supposed to choose your fuses to the size of your wire, not the device amperage draw. What I'm suddenly having trouble with though, is finding a good chart that shows which fuses for which size wire.
All the tables I can find are voltage drop tables, which aren't helpful I assume. Don't I need to know at what amperage 6 gauge wire spontaneously combusts? My specific project is a 20A 12V engine heater that I would like to fuse. I'll likely be using 6 or 8 gauge wire and the round trip run will probably be around 20-30ft.
My Google-fu is weak, please help me find what I need.
I have a sauna on my boat, therefore I win.
