Plugged new TT into 220v (wired wrong by electrician) HELP?!

good morning all. The short story version seems to be an all-to-common one. Electrician wired by 120v 30amp outlet that I requested for our new TT as 220v and when I plugged our new trailer into it last night, pop. I heard it pop inside. I turned the breaker back off and went inside the camper. None of the breakers were tripped and none of the 12v blade fuses were burned.

When I turned on the overhead 12v lights, they were really dim (but that's likely because the battery is low - hasn't been charged in a while). Is that an indicator to anything?

I spent the night searching the interwebs and reading all of the horror stories from "I just had to replace a couple of fuses on the converter" to "every appliance in the unit was fried and so was some of the wiring in the walls." (I cant' find the VOMIT emoticon but insert that here because that's how I feel right now).

So, I have a long list of questions that I would greatly appreciate any help with:

- obviously, I think the electrician should be responsible for this. He was told what to install and what we were using it for, and he didn't comply. Lets say for a second that he's not going to take responsibility and I have to turn to other options. Would either my auto insurance (of which I have coverage on the trailer) or my homeowner's policy like cover this?

- where do I start in checking/testing/repairing? I emailed Keystone to see if they could send a wiring diagram, but haven't heard back yet. Is there converter the unit behind my fuse panel with the heat-sink and cooling fan? It looks like to get to it, I need to remove the entire panel box that houses the breaker panel and the converter. Should I unscrew the square head screws that hold this box to the wall and slide it out to access it?

- I ran an extension cord from my house to the one small TV in the unit and it wouldn't power on. Granted, it was very late and dark and it's possible the my wife didn't have the extension cord plugged in all the way , but it sure seems like that TV got fried. What does that tell me? Should I expect then that all appliances are toast? Is there a solid way to test them one by one like direct to the units in some way?

- any other tests I can run on something to give more details of what the situation is?

Thanks in advance for any help.

  • thanks everyone. I did hire a licensed and insured electrical company, so I'm praying they take responsibility and things can get resolved smoothly. I asked for their insurance carrier...let's see what happens.
  • It is possible that the 110 volt equipment is damaged, but to say, "Everything 110 needs to be replace, everything" as eHoefler said is incorrect. Start by testing the things easily tested, like the televisions. Plug them into a known good, working 110 volt source. Some equipment may have just a fuse that will need to be replaced, while others will need professional repair, or replacement. The insurer for the trailer should be contacted if the electrician refuses to accept responsibility.
  • Another note. My RV has a generator and when i start the gen, it goes into a transfer switch before it goes to the 110 and inverter/charger. There is a chance that it damaged the inverter/charger before it got to anything else. But, like eHoefler wrote, go to your insurance company and let them start the process.

    Most legit licensed Electricians are BONDED just for this. Their Insurance should cover everything that has failed from their doings.

    Now if your Brother-in-Law was the Electrician doing this on the side then all bets are off for getting any help...

    Performing this simple AC VOLTMETER test would have caught the mistake wiring right away...




    Pictorials from GOOGLE IMAGES

    Even though you see 240VAC listed in the 50AMP pictorial keep in mind the 50AMP Trailers normally have two 50AMP 120VAC ZONES and only the very high end trailers would tap into the 240VAC usually for the washer/Dryer combos...

    Alot of us probably would do just what you did and turn it ON to see if all works ok. In hindsight you probably should have tested the circuit yourself first before plugging into it just like we do before plugging into the 30A and 50A pedestals at the campgrounds...

    Since you are looking at thousands of dollars here I most definitely would let the professionals handle everything..

    While I agree with the insurance aspects of this post, it's hard to say what was damaged without checking everything out. It's possible everything is toast like eHoefler said, or the damage could be more limited depending on how far the 220v traveled and where it stopped. Not an easy answer without a full evaluation. Sad to say I've read these types of posts quite a few times.
  • Oh fudge, sorry to hear this Contento. First thing I would do: wait to see if Keystone replies today and take their advise. If you don't hear from them, I personally would take the rig to a competent RV electrician to have them start testing the components. My RV is very complex, with 110/50 amp service, a generator and 12 volt batteries. 3 separate electrical systems that are wired inside the rig. I am sorry I couldn't give you specific answers but it is a complex system and no need to further the damage. I will follow your thread and hope for a simple fix.

    If you hired a reputable licensed business they would have general liability insurance and hopefully would cover the damage. Best of luck.
  • Likely not everything will need replacing. But you wont know what is good and what is bad until a thorough inspection. Get your insurance company involved or be prepared to spend a lot of money doing it yourself.
  • now I really need the vomit emoticon. So everything 110v =

    - A/C unit (all of it or would it be just a board/component)?
    - refrigerator (all of it or would it be just a board/component)?
    - that TV obviously
    - water heater (all of it or would it be just a board/component)?
    - microwave
    - stereo
    - I know the slideout motor runs on 12v, right?
    - does that include all of the outlets themselves and wiring in the walls?

    what am I missing?
