I have two 60amp maxi-fuses on two different circuits. One supplies full time power (headlights, dome lights, etc) and the other supplies power to the ignition (key on) circuits.
They are basicly dead-short protection...no matter what amp rating you use, if it shorts out, it's going to pop a fuse, which is what you want.
I prefer them because they are easier to replace than a stupid fusible link.
