Help with Wiring

Fuses vs. circuit breakers: there's no inherent reason to always prefer one over the other in my opinion. Probably circuit breakers are a little handier in most situations.

Fuses are generally less expensive and often smaller in size, but obviously cannot be reset. Circuit breakers can be reset and (depending on the type) can also be used as a disconnect switch. Either one, properly sized for the wire, will safely prevent overcurrent in the case of a short circuit or overload and so keep the wire from getting too hot and potentially starting a fire, which is of course their primary purpose.

I didn't think there was any difference. I like the idea of circuit breakers only so I don't have to mess around finding another fuse if one were to blow. The difference in expense really isn't that much.
