Fuses are sized to protect the WIRE, so the wire gauge will determine the correct fuse.
THIS is the correct and proper answer... LISTEN to this man
Putting a 40 amp fuse on a 12 ga wire is a good way to show of the last RV fire I saw.. This was a TT.. The TT had smoke damage to the outside, A good bath (perhaps with a bit of Clorox) is all it needed.
The Truck Pulling it was TOAST (Do not know why, Did not stop since Fire and Friend were both on scene already so no need for me to stop)
But putting a big fuse on a small wire is one way to do it.
The correct fuse for the trailer feed on GM trucks IS 40A. The OEM wiring is sized correctly.
