Junction Box Fuses?

I'm planning on re-wiring a trailer I just bought, and have already got most of the supplies, including a fused junction box. My question is what size (amp) fuses should I use for each of the 7 functions???

Nevermind. I got it.

Lowest Possible for the best protection.

That is correct too many people oversize the fuse and burn stuff. Like you said lowest possible to keep them on is the best protection. Good advice.
