50 amp wiring question
I'm getting a new trailer and it will be my first with 50 amp service. I've always noticed the standard NEMA 14-50R 4 pole receptacle on the AC pedestals but never paid any attention to the female sh...

"Why "top of the line"? "

We are at a campground right now. And believe it or not, just about 10 minutes ago we lost all power to the 5er (Montana High Country - 50 amp - both AC's running, it's hot). My laptop is on battery and my hot spot is my cell phone, so my laptop did not go out, nor my phone. But everything else in the camper did.
I checked the breakers in the camper first. All fine.
I checked the breakers in the shore panel power post. Nothing tripped. My Progressive 50 amp (portable) EMS just turned off and shut down the trailer. It did what it was supposed to do.
Power spike, or low voltage, don't know what happened, but something happened and the EMS shut the trailer down. I flipped the breaker at the pole, waited the 2 minutes and everything powered back up.
Air conditioners did not take a "hit" or fail due to low voltage, nor did the television get a sudden spike and blow up! Not to mention the residential refrigerator. I don't know if the EMS shut down because of spike or low voltage, most likely ... low voltage, as said, it's hot, and air conditioners are running everywhere right now all over the park.
Spikes, power fluxes, low voltage, sudden changes in voltages, you name it, a good EMS will protect the electronics inside the camper.
If plugged in at home, there not so much of a threat for provided electricity to fluctuate so much. I still keep the camper plugged into the EMS. However, at a campground, everyone plugged into the campground power is drawing, draining, exhausting, and taxing the electric lines and usage.
That's why you need a good EMS. (either permanently installed inside your camper or the portable one that connects at the campsite power pole)
