We have a 2020 390rk and overall it has been a great rig. However the 110v system is a frustrating mystery.

If we plug in an appliance in the kitchen that heats, eg. electric fry pan, the General breaker trips.

It seems the refrig, all outlets in the kitchen, the TV, the microwave and even the outlet in the pass through storage are on the same circuit.

We have a breaker marked Refer but it does not seem to be connected to the refrigerator. Same for the one marked Microwave, it does not seem to control the microwave outlet.

I contacted GD and was told they did not have schematics that were for a specific unit and could not offer any advice.

Has anyone else had this issue? If so, how did you resolve it?
 
One of the first things we did when we got this trailer was to label every outlet and breaker. We put colored dots on the outlets and on the breakers, so that everything that has a green dot, for example, is on the breaker that also has a green dot. Then, since we are now able to boondock, I made a list of the appliances and what they draw. That list is posted on the refrigerator, so that when we're running on batteries, as we are right now, we know what we can and can't operate together.
 
Did you buy this coach new? It doesn't sound like the current wiring is the way it would have come from the factory.
 
Sounds like you have some circuit tracing to do.

Maybe start with all the breaks off and one-by-one turn them on to see what powers up. It could be just a case of mislabeling - or, knowing how GD's quality control doesn't exist - wrong wires to wrong breakers.
 
I would agree with what has been said. If it was me I would get after it right away, figure it out and fix it. Suspect wiring and electrical problems in an RV need to be tracked down and fixed right away. Fire safety hazard.
