Progressive Industries Electrical Management System

Today I purchased a different adapter and will see if this fixes the open ground problem. Progressive Industries has told me that their system does not care or know the difference between 15, 30 or 50 amp services. So they are also suggesting that the adapter is faulty.

Well today I had the opportunity to try my new adapter and all works good. So this being said...I have 3 "puck" type adapters and every one of them showed the same, open ground, fault. Guess I have learned something today.

I plugged the PI EMS into my pedestal at home. It read 119 volts, 60hz, drawing 9 amps, with a message of E 0 which means every thing is A OK, as it should be with my home pedestal.

I just hope the ones I run across in my travels read the same.

This may be a bit off topic, but I have the 50amp built-in with remote and it works great when plugged into a 50 amp or 30 amp service, but when we plug into a 15/20 amp service, we always get an open ground fault? Have spoke with progressive industries, and they don't seem to have an answer other than the receptacle must have an open ground. But this happens always, not one specific receptacle. Anyone else experienced this and if so, what was the solution? Thanks in advance

There, fixed that for 'ya. Have you tested the 15 amp adaptor you're using to see if it has continuity from the female to male sides of the ground?

It is not uncommon to have this kind of problem with the M.I.C. hockey puck style of 15/30 Amp adaptors. In my case, the female round ground receptor had too much inside diameter to properly mate with the male counter part. I was able to crimp the female through the rubber using slip joint pliers to make ir work until I later replaced same.

My portable EMS shuts down due to either to high voltage & too low voltage. The EMS is a surge protector, high/low voltage protector, reverse polarity protector, plus a lot of other stuff.

If you have a hard wired PI MS, you should be good to go.

We have a 2002 HR with an in-house EMS. Is the EMS also known as a voltage regulator? That is, will it shut down my electrical system with too low or too high voltage? I'm aware it will prioritize systems when needed, but nothing in the manual indicates a shut down feature. Also, is it necessary to have a surge protector with the EMS? How large. The park where we are staying is having electrical issues with surging.

No, I got it strictly to use should I find the 30 amp broken.

However, as the poster after you suggested, it might be good to use it all the time since the 50 amp outlet sees much less wear than the 30 outlet.

Hope this question doesn't sound too stupid, but does the use of the dog
bone from 50 to 30 amp, give fewer problems, or more consistent power ?
I have a progressive unit also, and had one time it kept kicking out at a Campground due to faulty ground issue. Have a dogbone on hand , and will use it if it improves things, thanks Joe

Thanks for the idea. I had actually gotten the dog bone strictly in the case the 30 amp was broken. Hadn't thought about using it just because the 30 amp might be overly used and not very tight.

In general, 30 amp connections see a lot of wear and tear. I've been to CGs where even trying to fix the connection with some De-Ox-It just results in a spotty connection, so I just grab the dogbone, plug into 50 amps, and it works out quite well.

I know some people who always use the dogbone and 50A just because it tends to be less used, thus more reliable than the 30A connection.
