Electrical Connection

We have just purchased a new Rockwood Ultra-lite. It has a 50amp service; however, at home I don't have anything other than 120 volts (15amp) that I can use. It works to keep the batteries charged, but none of the wall outlets work when plugged into a 120 volt outlet. Is this working right or am I missing something? If I plugged our trailer to a Honda 2000 would I have power in the wall outlets?

Thanks for your help...

  • Check the breakers in the load center are not tripped. Can't always verify visually. Push them off firmly, then back on.

    Still nothing? Get out your multimeter or voltage detector. Remove the cover that will expose the wires and check each breaker has 120 volts to neutral.

    Post the results.
  • Many house receptacles are 20amps.



    Maybe it's not quite as bad as you think?

    In any case, you WANT to have a 20 amp receptacle installed. 15amp receptacles are often overloaded, overheated, and damaged in short order.
  • Using a voltmeter and with the 50 amp cord unplugged from the adapter, at the 50 amp end of the 50/30 adapter check to see that you have 120 vac between hot pin 1 and neutral and also that you have 120 vac between hot pin 2 and neutral. Those two hot pins should be jumpered together in the adapter. If you do not have 120 vac at both hot pins, then there is a problem with your adapter.
    If you have 120 vac at both hot pins, then you have a problem either in our 50 amp cord, or somewhere in the trailer.
  • You could look at your 50 amp load center inside the RV and look to see what other circuit is NOT on the same leg as your converter. That circuit breaker would typically be in an opposed location as to the one that powers your converter.

    IOW, if any or all of the other circuits in the RV operate, you could assume that your dogbone arrangement is correct and that a GFCI has been tripped.
    Sometimes, an exterior GFCI or one that is well hidden is in front of the wall receptacles. It pays to look them all over. Also, some circuit breakers are hard to observe if in the tripped position. Turning them off and then to the on position is a good way of uncovering that situation.
  • Thanks for the information... To clarify how I have connected the TT to power. I ran a hundred foot drop cord from the house to the TT where I connected to a 110 to 30 amp and then a 30 amp to 50 amp to the TT. The converter is working and charging the batteries; however, I have no power to any of my wall outlets. I have checked the ground fault outlets and they are ok. Puzzled???

    Thanks,

  • Let's start with the basics, How exactly are you connecting your 50A RV to the 15A outlet?

    Your 15/50 adapter would seem to be defective. L1 from the adapter should connect to both L1 and L2 of the RV. Or one of the breakers are tripped in the RV. Most likely the GFCI in the kitchen is tripped.

  • If using a 15amp to 50amp dogbone, everything should work. However, if you exceed 15 amps you will trip the breaker.
