How many times do I have to say it. There's no need for over current protection, IF YOU WANT TO BURN YOUR BOAT DOWN!!!!!!
This was a DIY bilge pump install with NO FUSE!!!!!!!!!!
The wire got so hot it literally turned from stranded copper to solid copper...... It luckily fused itself, & melted in two, before the boat caught on fire..
The wire is NOT supposed to be your FUSE!!!
