Accidentally plugged into 220v

So yes I made a mistake and wired the RV outlet into a 240v dual pole breaker at the house . The converter is toast . I have a keystone Laredo fifth wheel .

I took the tv and microwave out and tested inside my house. They seemed okay. At the time of the overload , the AC was powered off. So I know that itโ€™s hard
To say what else burned up. Iโ€™m hoping since the microwave and tv still work that nothing else was damaged . It was plugged In for about 20 seconds. Smoke was coming from the converter . The replacement converter will be here tomorrow. Hopefully this is the only damage.

I talked to my insurance company and they will cover any damage .

Just figured Iโ€™d post here and let you guys know how it goes.

At least I only have a $100 deductible ๐Ÿ˜•

Edit: The following page outlines the difference between 240v and 120v breaker layouts/installments.

https://www.thespruce.com/installing-a-240-volt-circuit-breaker-1824649

A 3-wire, 240-volt circuit has two hot wiresโ€”each supplying 120 volts for a total of 240โ€”and an equipment ground wire. A 120-volt circuit has only one hot wire connected to the breaker plus a neutral wire connected to the neutral bus bar in the service panel.

The wiring was fine. I just had the incorrect breaker. You can wire a dual pole 240v breaker to only put out 110/120v but, thats not the best practice and will more than likely fail inspection. So before you reply and comment about incorrect wiring, the wiring was not the issue, having the incorrect breaker was the issue.

how can a 30 amp rv plug fit into a 220 outlet? I have never seen one that fits.

More info pls. Must have been a 30A RV. A 50 A rv likes 220.
How exactly did it happen.
