Best surge protection

We just purchased a new Globetrotter 27fb. We are asking for opinions on the best electrical protection to purchase. Progressive seems to be the highest rated but wondering if you guys just use the surge protector or the EMS. There a $200 price difference between them and just wondering if we need the EMS?

I vote EMS! Protects from more than just surge like brown-out which can be common.
Saved my rig on several occasions.

Ems. The delayed restart for the AC and the low voltage protection are very useful to have.

Hi

If you are going to mess with something like this, go for the EMS setup. It's not just the protection, it also has readouts that a simple surge protector does not have. Shop around and the price isn't as bad as you might think.

Indeed none of these devices are magic. They only can do just so much. You still have to watch for various things. You also have to connect and disconnect the various bits in the right order ( = breaker off until all is plugged in, breaker off again before anything is unplugged )

You won't regret it. We've only carried them for 5 years but zero returns and I think you will love it with the lifetime warranty. The surge only units are popular too for the budget and certainly better than roaming around not protected but the EMS units protect from anything. Just have to have something. About 25% of our converters go out the door with a surge protector for reasons of got zapped, or don't know why it failed.

After reading with interest the discussion regarding surge protection and EMS, I purchased the Progressive Industries EMS-PT50X (not cheap). I am happy to report that this unit saved our AS some major damage due to low voltage last week. We were staying at a nice KOA which has special events over the weekend. As a result, the campground was completely full and the campground's electrical capacity became stressed. At one point I noticed voltage under 104 volts and the unit cycled power. After noticing a couple of cycles I shut the air conditioner off. This low voltage remained until the campground started to empty. I am convinced without our ems we would have lost our air conditioner! Thank you Progressive Industries!!!

i had the same issue

the campground was poorly wired.

we had less than 105v or even 100v at times.

THE EMS did its job and disconnected from the grid.

at 105V the uwave ran, but dod not cook properly.
we stopped using the uwave and the AC at the resort

Yep, brownout in my resort in Paso Robles over labor day. I got the low voltage shut down, when it came back up, only 107 volts on the display. I killed the power from the pedestal and ran off my inverter for the rest of the day.
Them 50 amp monsters really do drain the grid.

Hi

Pulled into a campground two days ago. Plugged in the EMS and went on with my setup chores. After a bit ... no power in the trailer. Check the EMS, it shows low voltage. Toggle the breaker, all shows good.....hmmm.... go back to setting up, still no power. Again the error.

Cycle things and E-0 ( all is well, timing out) comes back up. This time stand there and watch the voltages as it times out. As soon as it goes "clunk" to connect things, the error comes back and one of the line voltages goes from 120V to 2V.

Head over to the office and they agree to send somebody over. He makes it just as the first drops of rain start. I suggest he wait ... nope ... box comes open and he has it fixed in under two minutes. He's back in the golf cart and asking if it works on my end.

Of course by this time the rain is going pretty good. I got well soaked waiting for the EMS to time out again. I really can't blame that part on the EMS though.

Would the fault have messed up my trailer? I certainly would not have had power on one side of the system. Might the box have caught fire? I doubt it, but maybe it would have.

So does this *prove* you need an EMS? Not really. It does show that having one with a readout can come in handy. It also suggests that there is an advantage to having one indoors ....

50Amp Plug Does not Fit Surge Protector

Our 2018 FC 50Amp male plug does not plug into this surge protector. After arguing with Camping World - they wanted me to pay return shipping and stated that, if opened, no refund would be allowed - the issue was elevated to a customer relations person at Good Sam's. They will accept a return, pay shipping and refund the price.

I wonder if the EMS-PT50X 50 will work with my plug?
