50 Amp TT Plugged into 30 Amp Service
I hope this is the right forum for this post, if not, please forgive me! DW and I have a TT with a 50 Amp service/cord and have it parked on our lot at a private camp ground that only has 30 Amp service. We have a 30 Amp surge suppressor plugged into the pedestal, and then a 30-50 Amp adapter between the surge suppressor and the TT's power cable. So far, so good.....
We received a notice today about a vote to upgrade the campground to 50 Amp capability which I agree with. What I'm questioning are two statements in the newsletter that state running a 50 Amp RV/TT on a 30 Amp service will lead to appliance or accessory damage. I've searched the forums, and have not been able to find any doom and gloom postings or threads about plugging a 50 A into a 30 A. Am I missing something?

Nope, won't damage a thing UNLESS the voltage goes too low. Right now our rig is plugged into a normal 15 amp plug int he garage due to my 30 amp outside outlet being broken when our fence blew down. Have had it that way for months and no trouble.

No problem using a 50 to 30AMP. You just can't use 2 AC's the same time as the microwave and hair dryer. Or the breakers will trip usually on the shore power box.
If your surge suppressor is the kind that will cut electric off if volts are low/high. Then your appliance or accessory's will have no damage.

30a service to a 50a capable RV will not damage anything. One must be aware of load management due to the 30a limit is all.

Thanks all for the replies! Much as I thought, as long as I watch the amperage draw all will be good. Surge suppressor will also trip if the voltage drops too low so that is a plus as well.
I thought the campground might be painting a "doom and gloom" scenario

The only way damage could occur is if the contractor who wired the system assumed that the 30A outlets were 240V instead of 120V...

That being said what I'm reading he has definitely got enough safety inline. However I'm sure that not all campers are as protected and I'm guessing that was probably a form letter to everybody. Yes I have seen 110 Spike on one side of a 220 line like the campgrounds often use because of a ground fault.

I'm just wondering why you have a 30A surge protector, when you have a 50A trailer?
Or, do you have one of each

Simple answer on the 30A surge protector, that's what our previous RV system was and that's what our lot is wired for so I decided it would work just fine until the campground upgrades to 50A service (they say it's coming) and will upgrade then. Good question!
