Multiplus-II Wire Size Smaller Than Fuse?

I've purchased a Multiplus-II 24/3000/70, and the manual recommends a 300A fuse, but then only 50mm2 wire size - am I correct in thinking this would be undersized for a fuse of this size?

I'm also wondering if anyone has used a smaller fuse of say 175-200A?

I'd stick with the recommended size. The start current on the multiplus can be very high as its capacitors charge. If you do get a short, a 300A fuse will blow quickly.

Thanks. The 50mm 2 wire would be undersized for a 300A fuse though, wouldn't it?

Guess it depends how you're using things. Here not.
