Should I install 50 amp or 30 amp service?

We've decided to keep our trailer at a new location in our yard that is closer to the garage.

But, I do not have 30 or 50amp service available there and plan to install something. Our trailers have always been 30amp as is our current Flagstaff Shamrock. The trailer will sit 25' from the box.

One more thing that may help: We do not plan to upgrade anytime soon to a larger 5er or MH that would need 50amp (although that is a distinct possibility 10-12 years from now). Who knows if we will even own the house.

So, my questions are:
  • Do I just go with the 30amp because that's all we need?
  • Would there be any benefit to having a 50amp for my current 30amp trailer? (I don't think so but I've been wrong before ...)
  • Is there a big cost increase between installing a 50amp instead of the 30amp? This is not something I want to do on my own and I will have an electrician install whichever one for me.
  • Assuming we go 30amp now, is it hard or expensive to add 50amp to the same box in the future?

I would bite the bullet and put in both 30 & 50.

30 amp should be sufficient for your needs. If at a later day you buy a motorhome or trailer that is 50 amp, all you need is a 30 to 50 amp adapter to plug into the electric box.

Would you be planning on running two air conditioners on a camper parked there? Otherwise, 30A service should be more than sufficient. Also, pricing the wire size you'll need for 50A will help you decide.

I would recommend 30 amp. I have 15 amp for my camper right now. I will only use fridge and vacuum at same time so that's all I need and its already there.

So it depends what you plan on doing with RV there? Just cleaning and packing for next trip then I would say 30 amp. If someone could stay in there for a weekend since house is full I would still say 30 amp. Even if you have a 50 amp RV does not mean it needs to be connected to 50 amp service. Plus 50 amp is more for running 2 AC's at same time. Unless it gets real hot where you are, I would say save the money and get a 30 amp.

Price from 30amp to 50 amp will cost about double, possibly more. However only running a 25' span the price would not be too bad to do for 50 amp. I would go that route because you never know.

If money is not an issue run the 50 amp it will cost more if you have to run it later and then your 30 amp service is negated .

Just a thought - since you probably (per code) need to dig a trench anyway, why not run water at the same time?

Run wire heavy enough for 50 amp, but only put in a 30 amp breaker and 30 amp plug. If you decide you want (need) to go bigger in the future, just swap out the breaker and plug and voila!
