What I meant by the 30 amp service is I have yet to see any TT with 30 amp service (as a reference) that had a larger fuse at the battery. I can not speak for any TT's with 50 amp service, even though the shore power service is not related to the 30 amp DC fuse. Unless your battery is just about dead and the TT's battery is trying to draw more than 30 amps from the TT's charge controller.

My 2016 also has a metal, non sealed box. Inside you will find your wires, nutted together with inappropriately sized, dry condition wire nuts. It maybe overkill but I replaced the metal box with a plastic one with a seal. I also used push connectors and replaced the wire nuts.

My auto reset breaker was only a 20amp and would reset itself a few times if the converter/charger was trying to throw some bulk mode at the batteries.....it would reset itself enough times that the charger would drop to a lower voltage charge rate. I replaced it with a 40amp (since my power center is the 55amp model) and have not had a problem loosing bulk mode since. I have seen over 30 amps with my clamp meter going to the batteries.

If your charger is supplying a 30 amp charge to your battery it will only be drawing around 4 amps from your 30 amp shore power.

Battery fuse size is based on the size of your charger and has nothing to do with your shore power rating.

If that box is for the connection to the 7 way trailer cord. I would replace it with one of these if I had to replace it.
Searching in your TV for a blown fuse isn't fun.

Were you referring to my post? On my TT, the auto reset on the front of the trailer is connected to the positive lead coming from my charger/converter meant for 12V DC power, and based on meter readings is well over "4 amps" when a charge not a float is occurring.

Before I installed SOLAR, the most my TT's battery charge controller ever put out was 18 amps across the fuse, because the battery was at around 12volts. Most of the time it was putting out around 3 amps across the fuse (ceiling vent fan and a few LED's).
