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...

Thanks everyone for the continued comments (massive learning curve for me, so lots of good advice).
Initially, it was my intention to just replace the 7 pin cable and brake wiring. But as I got into it, I could see a bunch of corrosion locations, which I figured would bite me later so figured I would re-do/replace some obvious items. That is how I came upon the circuit breaker and as it was accessible, figured I may as well replace that too. Funny thing was, there were no markings at all on the old one, so I took it into an RV place and was advised to just get one which was the same amperage as the pedestal amperage for the trailer (in my case it is 30 amp), which is what I did.
As the junction box was a residential box and it was absolutely crammed with wiring, all connected with typical residential marrettes and a lot of corrosion, I purchased an RV waterproof box and re-did the wiring connections.
As to the brake wiring, I replaced with the same gauge wire and ran a single blue and white from the box to the centre of the axle(s) then pigtailed off a wire to each wheel. So, each brake has exactly the same length of wire running to it (don't know if that is relevant but the OCD in me said to do it that way).
I did purchase a brake assembly for each wheel, and my next step will be to replace the old with the new.
