Progressive Surge Supressor

Thought I would post my latest experience with a Progressive surge supressor.
We checked into Fort Wilderness with the family for Presidents week. I plugged my Progressive 50 amp surge supressor into the electric and my coach into the surge supressor and turned on the breakers. Went on to hook up the water, sewer and take care of the things that needed to be done when setting up. Went back to do something on near the electric panel and looked at the read out on the surge supressor. After going through all the normal read outs, it flashed an error code PE7- low frequency. Called Disney's maintenance and they sent a man out to take a look. He said he would need to unhook the electric and take the box apart. We had dinner reservations and had to leave so we powered down everything in the coach and left. When we returned, we hooked up to the electric again and found everything working perfectly. The maintenance man returned and said that the bus bar in the box was rotted and needed to be replaced. Don't know if the low frequency condition would have caused any problems, but I didn't want to take any chances. The surge supressor probably saved my electronics from any damage. This is the second time that the readout really helped. When I was camping over the summer, it showed a voltage reading of 104 volts, which is very low. Again it turned out to be a problem with the campground's electrical system. I feel that the money spent on this surge supressor was well worth it and would highly reccommed it to anyone.

Thought the Birkshire had a built in surge......

protector. I also have a separate surge protector that I used with my previous coach. Do I need to use it?

Couple of questions specific to this supressor......

How much $$ and where did you purchase it? Any pics?

You mentioned this is a 50amp model, (model number?) and I'm sure that's what the Berkshire needs. Our Georgetown is equipped with a 50amp connector, but I have adaptors to change to 30amp if that's all a campground might provide. I'm guessing you could connect the supressor to the shore line cord of the MH, then connect an adaptor down to a 30amp cord if needed, and then connect to campground pedestal?

This is the unit I purchased. It looks like it has gone up a little in price since I bought. I don't remember where I purchased mine from, but you can probably get it a little cheaper if you look around.

EMS-PT50C

Did a quick search and it looks like Tweety's has this for $350.

If you search a little more, you might find some one who has it for even less.

Thanks for the heads up Tom. We are looking at putting one in before we head out after tax season.

Why are people using surge protectors when......

the Birkshire has a built in surge protector (so I was told by lazydays tech). Sorry to be redundant but asked earlier and nobody responded. Thanks.

This was NOT my understanding. Dealer did say you would be fine and did not push it - but I thought the extra protection would be worth it!

I also picked up a surge protector when we first purchased our unit (does not seem to be as featured as this unit).

frequency is very tightly controlled in the US. i don't know what a campground can do abt it unless they are generating their own.
i can see surge suppression because of lightning and switches.
perhaps the suppressor is picking up on a phase shift between voltage and current. very common. that can be corrected.

i stayed at ft wilderness abt a year ago. was surprised at the number that spent the winter there.

I've not seen the need for a surge suppressor except just before my computer. i didn't install one on my house and did experience a surge once. lightning struck the electrical line and smoked the wire to my neighbors hot water heater. i lost a driver transistor in a clock...odd.
one of my coworkers did install a surge supressor in his house. it is just a matter of ur comfort level.

the more i think abt disney, as large as they are, they may generate their own and keep it isolated from the grid. seems like they do everything else out there. where i use to work, we generated part of what we used and part of the plant ran what we generated plus the difference from the power co. we had to stay in sync to do this.

if ur comfortable with one, do it. as with chicken soup "it doesn't hurt"

I had a 2 week old Prosine 3.0 get burned up by too high of voltage - I can attest to the need for one. My company repairs Inverters and we see them with fried inputs from over voltage all the time

Well I now have 100% proof that I made the absolute correct decision when I installed my Progressive Industries Surge Guard a few months back!!!!!

Went to local state park over the weekend.... Stayed Friday and Saturday night... Saturday night (when more people were there) we experienced three, yes - three, power surges. My Progressive shut everything down each time totally protecting my MH...

Just across from me was a guy in his two-day old 41' Fifth Wheel... Sunday morning he was outside his rig totally ticked off because he had blown almost every fuse and threw breakers all night in this new rig.. I asked if he had ever considered a surge protector and he didn't realize he needed one... I said - well now you know differently... Was upset that his salesperson didn't at least suggest one...

He took pictures of mine (hardwired in power compartment) and is ordering one for his rig....

I now know my unit is protected and that let's me sleep a lot better....

I also had my proof the second time I used my SP. While on a 4th of July camping trip at a new camprground the power went out. Turns out there were several blackouts & brownouts before my arrivial. One RVer for sure (but maybe two RVers) A/C units were damaged. The only downside I had was to be without power for 18 hours during a heat wave but I was thankful to have my SP when the campground lost power 20 minutes after I pulled in.

Any of you electricians find this weird?
How does a "rotted buss bar" in the power pedestal cause low frequency?

Inquiring minds want to know... Sounds fishy to me as I thought the frequency of the alternating current is determined at the generating source (or sub station transformer).

Ernest,
I see your are from Tyler so I assume this was Tyler State Park. We were there as well, (and 8 days before that). We were parked right across from the 2-day-old guy. He mentioned you and the problems he had. We had no problems (but no surge protector to notify us either). We were probably on a different circuit. The power system there looks pretty new, and there weren't that many people there, so I'm surprised there were problems. I checked with a meter before we hooked up and everything was good at that time (121 volts). Obviously things can change.

Exactly. I can understand 'low voltage', corrosion or water intrusion being the culprit. But I'm no electrician. I don't even play one on tv.

Barry....


I guess it was a different circuit because I definitely had three distinct surges all three of which were caught by my surge guard...

i'm curious...how many other campers had problems? do u have any pictures.
how was the weather? much lightning? lightning does interesting things.
most of the things i'm reading abt here are not surge supression. most are talking abt one of the built in features of the surge guard that shuts it down on high or low voltage. the suppressor part would take care of the rapid spikes.

Great weather.... Don't know how many others had problems... It's and older park and I have no idea how long it's been since they have reworked the electrical - if ever... It's easy to tell its an older park because most of the pull-tru sites are small and not designed for 40' MH's... Mine wouldn't fit in the first site they assigned....

Fine weather. No storms at all.

Did you take some readings when your protector said there was a problem?

I know the other guy with the new camper said he was having problems, but who knows.

If I wanted to sell surge protectors, I would get more customers if my suppressor reported problems than if none were ever found. This is just an observation and not based on any fact what so ever.

yeah, there is no telling. lightning would have been easier to understand. it can fry one or even one item and all else is unaffected.
