If the EMS is a Progressive Industries brand, they have a built in time delay on turn on. So, if there was a long enough power outage, maybe that started the time delay. In an RV it's sometimes hard to recognize a power failure flash because only the 120 volt devices react. I don't have experience with a power flash of a few seconds but I see the time delay every time a turn the pedestal breaker on. As stated a ground fault is only dangerous if there is a short somewhere. I would have no problem going without the EMS for a 30 amp connection upon a ground fault. However, 50 amp 240 is different deal. A ground fault there would have me worrying about the wiring integrity. A bad neutral on 50 amp can cause voltage swings enough to damage things. Note: neutral is different than ground. As stated above, using a dog bone to connect 30 amp into the 50 amp side would be good idea for most any kind of trouble with the 30 amp outlet.

You were promised by the RV park that they supplied “good” electrical power. They broke their promise and, I’ll wager, offered no refund.
If the EMS has a ground fault circuit then the problem could be with the trailer,not with the campground electric.I have come across a few trailers that worked fine on regular recepticales but would trip a GFI circuit because they have a very small leak to ground. Now if the EMS shut down because of low voltage,then that could be the campgrounds fault or even the utility providers fault. When everyone is running their A/C's,the voltage will drop. And now you have people with electric vehicles plugging in which will make things worse.

An EMS only looks at the incoming power. You could have an open ground issue in the RV and if the power coming from the pole is good the EMS will still send that voltage through to the coach after the programmed delay.

Link? Why? If the campground has a low voltage problem already with just RVs plugged in, plugging in EVs too will not make it better.
