For 30amp Trailer, install 30 or 50amp service to pole?

Hello All,

I've got electric at a private camping area and need to add service for a 30amp plug for a new 30amp travel Trailer. I heard it better to put in a 50amp outlet in and then use a 30-50amp plug to hook it up the trailer. That way I would have extra or reserve power for everything on my 30amp trailer to run.

Smart or Dumb? :-)

  • Thank you all. I'm going with a 50amp in case I ever get a 50amp camper or add an ac or more electric devises to the camper.

    Thank you again

    When I installed a pedestal at my house, even though I only had a 30 amp RV, I installed a 50/30/20 pedestal and powered it with a 50amp 240v breaker. While going to the expense and trouble, I figured that if I ever decided to get a 50 amp RV, I would not need to re-do it. The extra cost was relatively small compared to a 30/20 pedestal, and was negligible compared to the cost of doing it twice. There was no extra trouble, since I merely pulled one extra wire (although I did run 6g wire instead of 10g wire).

    While a 30 amp is sufficient for now, be prepared for the future. "Do it right, do it once."

    this is what i would do. never thought we would go from a 30 amp TT to a 50amp TT but that happened about 2 months ago. i would spend the money and do it once. this is a nice setup
  • At home I installed 30A service, even though I will eventually have a class A. However in your situation I would run 50A. Get a box with 50, 30 and 20A connections. Use a 50-30 adapter to your trailer this will leave the other leg free when you want to use the 20A service. More is always better when it comes to electric!
  • If you want to be able to use your air conditioners then go 50. Even though your rig is 30 amp think of the future and the possibility of getting a 50 amp unit. You never know. If you just want to keep the battery charged then do the 30 amp and you will still be able to use your air and lights anyway. All is dependent on how far away it is and what gage wire used.

    If you install the 50/30/20, you won't need the 50-30 adapter. Just plug in to the 30 amp outlet. The 20 amp outlet will still be on the other leg. (On a related note, using the 50-30 adapter on a 50 amp outlet only gives you a 50/50 chance of having the 20 amp outlet on the other leg. The 50/30 adapter taps one of the legs, but you don't know which one.)

    While I agree with going 50 amp (I am the one who posted the picture of the 50/30/20 pedestal), you don't need the 50 to run your air conditioners. In a 30 amp RV, they will run just fine on a 30 amp outlet.
