Then you are not protecting the various circuits. That would be like splicing all of the connections in your house to a main breaker.

The fuses should be sized to protect the smaller wires.

Imagine tying various outlets in your house to a large breaker. Now instead of popping the individual breaker, the wires will be the weak link, and burn out in the walls first.

In your example above the right way would be to put a 30 amp breaker or fusible link as close to the positive terminal as possible, then your #8 wire feeding a fuse block, and the individual fuses sized for each circuit.
