Using 30 amp at CG

2007 3400RL. At home I hook up 50 amp (had a plug installed by my front door of stick house) when loading and unloading, then the night before we leave I just use a heavy 110 cord to hookup to keep the fridge and small chest freezer running until we head out. On previous trips we have always had access to 50 amp, which we almost always needed as we camped in hotter months and needed both AC's. Starting to do more fall/winter camping and anticipate going to parks that only have 30 amp. I have the appropriate adapters to use 30 amp CG supply and realize the major limitation is I will not be able to run 2 AC's at once (any other major no-no's with 30 amp only) but my question is: I never want to plug in without the protection of my big 50 amp surge protector. If I plug in to the CG supply with my 30 amp adapter, then in line to the trailer would be the surge protector, 50 amp cord, then trailer will I be OK? Or will the 50 amp surge protector give me error messages and/or not function as it should and/or prevent me from having electrical supply? TIA.

Depends on what you have. Ours works on both.

I read RVTravel.com there is an electric guru there that answers your questions. I asked him if I needed a 30 amp surge protector or if the 50 amp one that I have is ok to use at a 30 amp hookup. According to him the 50 amp, used just the same, works just the same with 30 amp.

My Progressive works the same as it does on 50 amp. When on 30 amp, I do not use the electric hot water heater, and I try to remember to turn off the fireplace when using the microwave or other high amp kitchen appliances. I have tripped the parks breaker a couple of times in the past.

Thanks for the responses. We have a Surge Guard Model 34850 made by Southwire. Bought it at CW. As long as it is connected between the CG pedestal and the trailer does it matter if it is closer to the pedestal than the trailer? Still OK to use the 50 amp "anaconda", correct?

Should work fine although I never have had the product you have and have to figure it works same as progressive.

You will be fine with the 50 amp cord, the 50 amp Surgegard, and an adapter to connect to the 30 amp receptacle. You can put the Surgegard next to the power pole or next to the RV connection. Being next to the RV enables protection for the 50 amp cord from the pole to the RV.

We run more on 30 amp than anything else. As said before, turn off the electric water heater, consider running the refer on propane and run no more than one high amp draw device at a time.

DW is an excellent CB tester. Our TTs were all 30 amp and I cannot think of a time when she did not pop either the pedestal or the inside one.

I think a couple of times were on purpose
