In here there is no such thing as a stupid question, those are reserved for wives and teenagers.
Your one wire alternator has an internal voltage regulator. I don't see anything wrong with your setup as long as your breaker can handle the amperage output from the regulator. You didn't state the amperage rating of the breaker or the brand of alternator.. With the way you have it configured your breaker will act as a surge protector helping to protect the battery from excess voltage should the regulator in your alternator go haywire.
If your breaker trips you should get a low/no charge indicator on the dash if indeed you have such an indicator on your instrument cluster. If not you will know soon enough as the battery will get drained without a charging current.
