The breaker should match the rating of the lowest capacity part of the circuit which is not protected by a lower capacity fuse or breaker down-stream. This is one thing that bothers me with these alternator conversions. If you just throw a big alternator in there, and run it through existing wireing, you may exceed the capacity of another component (likely a wire) due to rating or age. You need to make sure that the wire from the alternator output to that breaker is good for the full alternator output/breaker rating. Then you need to make sure that any connection between the breaker and the main bus, and between there and any other device not protected by an intermediate breaker or fuse is rated for the full load and is also currently in adequate condition to handle the load.
