Wiring fire, advice sought!

Hi Tim, Just like too many people in a group going to a movie!! All good advice,but which one to pick! I'm "no" electrican, however I think a 60A is a tad bit high. It's like wrapping tin foil around a blown fuse. To me the Idea is to protect your system. If a fuse or link is rated to high it's "whats the use". Too high amps would by-pass your link and melt down your wires. I would suggest if you have a 40A... to put it in. Just my suggestion...you or "I" may get more advice on this one.
PS Like Robbie stated If you have a 10G wire...Put in a 30A link
