Your question brings up IMO an important point for both CBs and 12 fuzes and that is one should make sure they understand "EXACTLY" what each CB and each fuze protects and make a list now before you have a problem. This should have every 110V and 12V light, appliance, item that uses either 12 or 110 v power. This is critical when one item goes out since that way you can trace where the issue might be.l I keep a copy of my list taped inside the converter power cover so I know where it's at when and if needed.
P.S. don't forget to include the actual ground fault items since some outlets on that might be there more from convenience than actually being required by code.
