Elctrical Circuit Issue
So today I did a stupid thing. I hooked my battery up backwards and now I have no lights working off one circuit. I blew the two fuses on the converter. Before I replaced them I had no power for fr...

A reverse polarity from the battery will NOT cause the main fuse or CB (if there is one) to blow or open the circuit in the case for CB.
The OP said it was a WFCO WF-9855, but that's just a stand-alone converter, so he's more likely talking about an WF-8955, which is a power center which has the circuits and fuses he's talking about. And yes, connecting a battery in reverse will blow the main DC fuses, which are between the battery and the converter/branch circuits.
Straight from the WFCO manual: "If the reverse polarity fuses are blown, it means the RV battery was accidentally connected in reverse, either at the battery or at the converter...These fuses protect the converter from damage in the event that the RV battery is accidentally connected in reverse. A reversed battery connection, even for a second, is the reason that these fuses will blow."
It's clear from your comments that your knowledge of electricity rises only to the "knows enough to be dangerous" level. Please refrain from spreading that danger to others.
