Onan 5500 Gen in RV

Right above the stop/start switch there is black plastic part with plastic door on right end and when you open it there are two in-line-fuses inside. There appear to be spare ones. Where are they for?

I don't see any place for in-line-fuses. On end by breaker switches there is a 20 amp red breaker fuse with two blades.

Can find anything in my manual and can't find manual on line.

    ON EDIT: Oops, I think I read your post too quickly on my first response.

    There should be a breaker for each 120VAC line. Not sure about the inline fuses, they might provide protection for any 12V operated devices on the generator (choke, fuel pump, ?).
