I was looking in the documentation and was unable to find info on what rating the breaker should be. Perhaps someone else can look at theirs.

We tend to think of 12ga wire as 20 amp but automotive wire is usually 105C rated (because engine heat) and that would handle probably 35 amps safely. I suspect the circuit breaker itself malfunctioned from age/corrosion. If it already seems toast, maybe pry it open and take a look at the internal condition.

If you are rewiring I would upsize the wire to 10awg (because why not) and put a fuse or second circuit breaker in line (30-40 amps). I wouldn't trust the factory breaker after what happened.
