I have read a lot of threads about using an adapter to plug into the 50A if you start having issues on the 30A. It was for this very reason I bought an adapter 2 years ago. Still in the package until last Friday. We were at a state park and it was packed. Maybe 5 rigs that would have 50A plugs and the rest all 30A TT like mine. Before we were done getting supper ready I lost the A/C. I thought that was odd. Checked and my breaker in the TT had popped. Checked the one on the pole and it was fine. Made me wonder. So I grabbed the dogbone and put her in the 50A hole and never had an issue the rest of the weekend. Don't know why it did it. Only thing I could figure was that it was Friday evening and a steady wagon train of people coming in and setting up and firing up their A/C units probably put a big load on the 30A circuit? I don't know. My rig is only a year old so I can't imagine the breaker is weak. But who know. At least I had the adapter. Thanks to the good folks here for that recommendation.

Do you have a surge protector? If you don't, I'd invest in one sooner rather than later!WoodGlue

The A/C breaker in your TT probably tripped because the park's voltage had dropped because of the load from all the campers and that caused your A/C's motor to draw more current. Most likely the voltage drop on the 50A circuit was less because the wire gauge is larger and fewer people were on that circuit.This assumes, of course, that the 50A and 30A circuits on the pedestal are fed by different wires which is the proper way to do the wiring since it is possible (although unlikely) that both the 30A and 50A outlets could be use at the same time. However, I am pretty sure that at many parks the 50A and 30A are not independent of each other and this argument would not be true.

I did the same thing, had my adapter in the package, never used it until last year. We were camping and the breaker on the pedestal kept kicking off. I thought, I will fix that. I got my adapter, hooked up to the 50 Amp service, never had a problem. The 30 Amp gets used and abused a lot.

That Friday evening would have been a good time to monitor voltage in your RV.

I don't have a surge protector. I have considered one but I don't want one that hangs outside for theft reasons. Part of the reason I don't have it is that I am not really ready to dig into wiring one in.

As a general rule, I will utilize the 50 amp plug if available at the pole for these very reasons. I do have a surge protection circuit and it displays incoming voltage and current load. As a side not my surge protector went bad on last use. Had to bypass to make work. Manufacture sent me out a new board to replace and now all is well.
