Did I blow my converter?

I just bought a 1997 Winnebago Adventurer 34RQ. When I built the house I had the electrical install a 30amp service in order to connect to a generator. I connected the mh to the outlet.

Generator must connect to an inlet and the system should have a transfer switch or lock-out device to prevent back feed to the grid.

An RV outlet should be wired to a single breaker to get 120 volts. This is written right on the NEMA TT-30 outlet.

The electrician did both wrong and should be held responsible. Have the items inspected and permitted by the city or at least a real electrician.

Generally a converter should have 120 vac in and gives 13.6 vdc out. Yes, converter is probably shot.

Not too soon to get a PI EMS to protect the RV from over voltage, under voltage, bad ground, reverse polarity, and poor service.

There are so many problems here I don't know where to begin but I'll try.
An "outlet" to connect a generator should actually be an inlet, that is, male connection. Otherwise you need a cord with 2 male ends to connect your generator and these are dangerous.
A generator connection should have an interlock or transfer switch to prevent the generator connection from ever being connected to grid voltage. Without this grid voltage could fry your generator and/or your generator could power the lines on the otherside of your transformer with thousands of volts and kill an unsuspecting lineman.
No generator connection should ever involve a 30 amp RV outlet. Your RV plug shouldn't have fit into this connection in the first place. Even though he used a female he should have used something with 4 prongs, the best choice would have been a twist-lock configuration.
IF, and that's a big IF, your RV uses a 50 amp service then you WOULD measure 240v between the hot legs. Why stuff blew up? Well, perhaps your idiot electrician also mis-wired the outlet and put the hot on the neutral or ground.
Either way, I would say anything in the RV is now likely damaged.

The only good part of this is your orig converter was junk to start with. Now you can get a good 3 stage converter (Progressive Dynamics) and enjoy all its benefits.

Never ask a car mechanic to work on your airplane...

How many now does this make? Three dozen listed on this site?

My recommendation is that you yourself personally let a professional who knows what they are doing do the install for you.

You need to examine the socket. Obviously there is a 2nd LINE voltage connected to where a neutral should go. Not only does a line connection have to be there it has to be in the right place. So does NEUTRAL and so does earth ground. And all three circuits have to be connected to the right pin for it all to work.

Do you know what neutral is? How to find it in the circuit box? It has to by code be a white wire. Your breaker is most probably a ganged double breaker at the moment. You need to switch it to a single breaker. Have you any experience doing work like this?

Do you have the aptitude to disassemble your converter and check continuity through soldered on tube glass fuses?

"Someone told me's" have caused fires and fatalities.

It is highly likely your converter is irreparably damaged.

Check the breakers to see if the one for the converter popped but normally, if 240 got to the converter, it's toast.
Sorry!
