30 amp MH in a 50 amp CG

New to the Forum and Proud Owner of our 1st MH - a 2016 Thor, Four Winds 31E. WE have had numerous TT's for years but they were setup on a Seasonal Site for over 15 years, so we are somewhat familiar.

I'm NOT sure if I'm in for some sort of Problem and/or Issue????

We have a reservation at a CG that 'ALL' sites have 50 amp Elec. The Owners Manual says that the MH has a 30 amp Elec system. The MH did come with a 30 amp connector on the 40 ft cable. Also included was a 30 amp female to 50 amp male adapter. I assume that this is for just the instance that is coming up.

I DO HAVE a Progressive Industries Surge Protector, but it's for 30 amps ONLY.

Would greatly appreciate any and all ideas and/or suggestions.

Thanks and The BEST to YOU & YOURS.

30 amp MH in a 50 amp CG

prndl....... Congrats on your new Thor!! Many pleasant miles ahead.

And welcome to iRV2. This is the place for...... whatever you need!

As to your plug in-- you'll be fine just as you are. That thing you have (referred to as a "dog bone") will enable you to plug your 30A cord into a 50A socket. You may not even need it, as most CGs that bill themselves as "all 50A" actually provide each campsite with each type of receptacle, one 30A and one 50A, to handle just such a situation as you have.

As to protecting your coach, your Progressive unit will do the job just fine. When you plug your 30A coach into a 50A line, your coach will still only draw whatever electrical power it needs. There will still be the higher amp capacity available from the system, but nothing in the normal setup will try to cram 50A down your throat.

Enjoy your trip!

Most all 50a are 30/50a with plugs to accommodate both. If not then a dogbone converter. Your PI should still work ok.

Two options.. I suggest you be prepared for both

ONE: Most 50 amp sites also have a 30 amp plug (and a 15/20 amp duplex outlet like the walls in your house as well)

If this is the case.. Just plug into the matching outlet after testing it.

Option 2 is to get an adapter from your favorite source (E-bay, Amazon, Wal*Mart, Camping world, Generic RV store)

As others have said, just plug into the 30amp outlet if available or use your dog-bone adapter.

As far as your surge protector, plug your shore cable into it, then adapt the cable from it to the campground post as has been said. You are go to do.
