Power Problems at Campground

It is a 30amp hookup and I used a Camco 30 amp surge protector.

Surge protector only or an EMS w/surge protection? What model? What was the voltage when you lost power? If what you have is actually an EMS then perhaps the source voltage fell below the low voltage threshold and the EMS did exactly what it was designed to do - disconnect power to the trailer.

Does this happen at other plug ins, at home for example? What was the weather looks? Was it dry, or have recent wet weather? With wet weather, the rain may have seeped into somewhere. If its dry, or happens at other locations, it may be your cord or trailer.

I would do some minor maintenance.
Disconnect from shore power, remove cover from 120 volt AC power panel. Inspect and tighten all the electrical connections paying attention to the white neutral connections. Look for wrinkled or melted insulation on the wires.
Is this what you have?
Camco Surge Protector

Any chance it is a GFCI breaker?

How much power are you using? Put the fridge and water on propane only.

I am using the Power Grip - Voltage Protector - 30Amp. It does not show the voltage, only lights to indicate an issue. I have used it many times at various campground with A/C on and had no problem. The campground power at my site only, cut off and I had to reset by turning power off and on again at the pedestal. I will try this again at another campground in a few weeks, just want to make sure my rig is ok before a long summer trip. I think it was a problem with the campground pedestal but want to be sure. Thanks for all you suggestion, I will check them out.

I had similar problems this spring with 50 amp surge guard. Would shut me off sometimes immediately, sometimes intermittent. Tested every power pedestal and all checked out good but still had the problem. In three different cases, three different parks I moved to a pedestal on a different circuit and problem disappeared. Any kind of fault will cause that to happen. In my case the voltage was never too high or low. It was detecting some kind of fault . In my case I think the surge guard was doing its job even though I think the coach would have been fine on the same power with out the guard. Mine is permantly installed

What have you got running? Sounds like you may be overloading the 30A circuit.

So it's this Camco 55301 Voltage Defender EMS ... an example why a model with voltage display is more useful. Low voltage threshold is 102 vac for this model and I'd suspect it's just doing what it's designed to do - disconnect power to the RV whenever the supply voltage drops below 102 vac. Without voltage monitoring though you're just guessing so I'd suggest you invest in an inexpensive DVM so you will know what that incoming source voltage is.

If the breaker is tripping you might simply be using too much power. It's pretty easy to do. 30 amps is not much power if you have 1 A/C running.

30A power outlets are not gfci, only 20A and less. Thats not it.

Breaker tripping in ped. , replaced with new by camp, still tripped., but not in camper main panel. Thats amperage overload that could be caused by poor connections or undersized wiring downstream of the breaker. Assuming your cable to the rig is a 10/2 in good condition then it may be poor connections in the ped between the breaker and outlet, or in your rig where your shore cable connects into your panel or junction box.

Poor connections will heat, which causes resistance, resulting in low voltage. As the result, amperage increases to supply the wattage demand. Its why welding cables are so big.

Several times we have had connections on our side overheat, its age and corrosion due to weather in outdoor environment. We fix it right away, its not something that can be a preventative maintenance issue. Inspection yesterday, cannot see a problem tomorrow. Its like a car, it ran fine this morning, broken down now.
. A few times we have found a heated weak connection in someones camper. Inspect your connections ,cable , junctions, then have the camp inspect and verify adequate sizing, sound connections.
Knowledge of wattage of your load to keep you below the threshold of your available amperage would help you convince others that the problem is not yours. And add to your safety.
