MikenMpls - your winch acts similar to a 12 volt DC car engine starter, when first engaging motion, it requires much more amperage. And even more so for a winch, I’m guessing maybe 2-4 times until the load (i.e. dragster or stuck vehicle) is moving. Due to this initial amp loading, selecting a correct fuse is not so easy without calculating your specific locked rotor amperage.
If you’re interested in a safeguard, an easier route is to install a shutoff switch inline on the positive cable between the battery and winch. When using your winch, turn on power. If your winch overheats or has another issue, you can turn off power immediately, as opposed to having to disconnect a cable from a battery terminal.
My latest Summit catalog, page 100 shows a Hella Battery Disconnect switch for $17.25. Max continuous rating is 100 amps at 12 volts, Max peak load (for 10 seconds) is 1,000 amps at 12 volts. Alan
