Accidentally plugged into 220v

[xnizstudio]

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 it’s hard
To say what else burned up. I’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 I’d post here and let you guys know how it goes.

At least I only have a $100 deductible 😕

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 wires—each supplying 120 volts for a total of 240—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.

Lots of ignorance on this issue. Take a look at your 220V electric dryer outlet if you don't know how a 30A RV plug can fit into a 220 outlet.

Do you really think I’m stupid enough to force a plug into a socket that doesn’t fit ? I’m not that ignorant. It was an honest mistake that the guy sold me the wrong breaker

“Had someone wire an outlet from the house...”

Even a pro might blow an RV plug install.

Did you not read the original post? It was a 30amp camper RV outlet ran to a 240v 30amp breaker . The only ignorance is the guy at Lowe’s sold me the wrong breaker .

please tell me that the "someone" was not an electrician. :h A real electrician should know the difference between an RV trailer 30 amp 120v plug and a 220 30 amp outlet. wowza
Hope not too much is messed up on the camper. good luck. 🙂

He knows how to run wire and outlets . He just didn’t know campers were 110v. The guy At Lowe’s didn’t know either because he sold me the dual pole breaker . ?????

Monitors and thermostat run on 12V so should be fine. Potential is there that you burnt out the 120V fridge element, but with just a short duration, it might have survived.

EDIT: Check the electric element on your WH if it was on. Also check anything that runs off of a wall wart. Might have fried the wall wart itself.

Right now the converter is disconnected . There isn’t any way to check for power without the converter right ?

Like.. does the converter power all the electronics ? Can I plug the camper into the 110v outdoor socket without the converter connected ? What does the converter do aside from charge the battery ?

Yeah I think it’s gonna be okay. The microwave seemed okay. I’ll double check the microwave when I get home

Sorry to hear. This happens quite often to people. You're right in your assessment- if things were off, they possibly/probably survived.

For future, you might want to invest in an electronic monitoring system and always use it (hard-wired is best for that). It would have protected you in this case:

Yeah I’m hoping the refrigerator, monitors and thermostat is all good. That’s my main concern. Fingers are crossed !

[xnizstudio]

Should have checked the voltage before plugging it in . I’m swapping the breaker now for a single pole 110v . Tomorrow I’ll install the converter and see what is toast.

Had someone wire an outlet from the house to a 30amp outlet before the camper arrived. It had double the voltage because it was a duel pole breaker . So it was a 30amp 220v braker

[fj12ryder]

Yeah, me too. What plug did you use?
