Main Fuse 100A next to battery?

[Pskhaat]

That fuse box next to the primary battery's positive terminal. There are four fuses listed on the top, first one is ALT-S (I'm assuming this is the ``alternator good signal'') and the next one is MAIN. There's no fuse in there for MAIN. Should there be? What then would that possibly be for?
