My new 2020 Jayco GrayHawk Prestige 29 MVP is 30 Amp power. It has a Electronic power Management System to allow the TWO Air conditioners to run on that 30 amps. Question...Is this 'EMS' the same as a Surge Protector like the Progressive Industries EMS PT30X or should I add one?

Can't hurt, considering the cost to repair/replace electrical problems.
Sometimes the semantics get confusing with all sorts of duplicity, and acronyms get reused as well, just to increase the confusion.

The specs I reviewed do not indicate it has standard surge protection.

OP, are you concerned with low voltage? An autoformer should be considered IMO.

While your at it, get yourself a plug in volt meter. I keep it plugged in the rv where I can view it. You would be surprised to know how many CG's have poor voltage when they become crowded and everyone is running things like two AC's.

The last KOA I was at showed 92 volts coming off the pedestal. I then plugged in my 'Hughes Autoformer' to boost me up to 110 v.


I protected the Hughes by first installing to the pedestal, a Progressive Industries surge protector SSP-30x @ $100 plugged into the pedestal.
Then I plugged the Hughes into that. The SSP 30x protects the expensive Hughes at approx. $400-500 or whatever they cost today.
Even though the Hughes has a little bit of surge protection built in, it is not that much , that's why I added the SSP/30, it offers protection of the entire package that follows it in line.
The third piece of the puzzle is a Surge Guard 34931 at approx. $350 which protects the rv. That plugs into the Hughes.

So to review the order, its the pedestal, the SSP 30x, the Hughes, then the Surge Guard then into the rv.

An electrician advised me to set it up that way. The idea is to sacrifice the cheapest component, being the $100 PI SSP-30X , to protect the others incl the rv.

So far after using it this way for years, nothing has been damaged and I've been thru power outages and poor state/county grid systems that simply can't handle the loads. I cover the entire package of 3 devices inside an altered tote box to protect it all from rain and keep it all out of sight. Its all padlocked to each other as well as the pedestal. I place 2 extra large dog bowls and a spiked dog collar with a chain on top of the tote box. Nobody has every bothered it and I don't have a dog that big.

If I were you I would buy the best one that Progressive Industries has. This is no place to skimp. I have seen a case where the underground cable from one pesto to another failed and caused high voltage which caused a lot of damage.
If you ever think that you might get another RV in the future that would be 50 A I would get the 50 amp version from PI and use a 3250 amp dog bone adapter. The 50 amp receptacles on the pedestal are usually in better shape than the 30s. Sometimes the 30 amp pedestal receptacles are so worn that they caused an excessive amount of heat at that point.
You may call me on the phone if you want to talk about it further.

I don't understand how you got from 92 volts to 110.

Hughes claims a boost of 10%. 92 volts x 1.1 = 101.2 volts.

"The unit automatically starts boosting 10% if the voltage drops to 113 or below. It will boost 10% until the voltage gets to 90 volts which is the minimum amount of volts for the unit."

Is it an earlier version?

Hi, hope all is well. Yes its an older unit 1980's, I used it when I was a seasonal for 17 years . I don't remember the rate its suppose to boost.
Thank you for pointing that out, I didn't mean to be misleading. I was using the 92v to 110v as a general term for all the pedestals that I tested at the time.
At the time I tested a few pedestals at my neighbors sites. They used my meter to test their pedestals and I remember they all were in the 90's with 92 being the lowest and all went over 100v when we tried the Hughes. To clarify, the Spread was 92v to 110v.
The system Im using seems to work well, I have never had anything burn out. At the times when my was pedestal was very low, I turned off my AC and just tried to protect the rv appliances and converter.

Stay safe [emoticon]

Bobndot, Hughes plug-in volt meters are $15 on Amazon. Mine works well.
