Electrical Help Needed
As part of correcting a no brake issue on our trailer (small 23 foot), I decided to freshen up and rewire some components of the braking system. I will quickly admit, I knew/know very little when i...

First, again, many thanks for the continued information. I have/am learning a heck of a lot as I work through this stuff.
Regarding what I was informed by the RV employee, I realize the pedestal power is AC and the battery system is DC, but as the lady who I spoke with has been in the parts section for at least 15 years, I thought she was knowledgeable and that there was some sort of relationship between the DC system amperage and the pedestal amperage. And I showed her the old breaker and told her it was connected to the battery...Go figure.
I checked the Converter and it appears it has eight gauge wire and from manufacturer details on this Converter (WF-8955) the output power (rated DC current) is 55A and max input current is 11A. Not sure which number is relevant, but if it is the output power, does that mean I need a 60 amp breaker?? Afidel, not sure this is the same as "charging circuit" and "charger rating" that you mentioned.
Thanks,
Marv
No, do not use a 60A breaker or fuse.
You want the fuse or breaker to protect the wire from overload and potential fire.
8 Ga wire, 40A fuse or breaker..
That is typically the amperage RV manufacturers use.
The fuse or breaker on the tongue is there to protect the wire connected to the battery, on the converter end there should be a dedicated fuse for the battery. The idea is you have two power sources and because of that you should have a fuse or breaker on each end of the wire nearest the power source.
You can of coarse under size the breaker, 30A is perfectly fine and well within the current rating of your wiring.. The only issue may be occasional breaker trips if you are using amperages close to the breaker rating.
