I've got a Progressive Industries EMS-PT50. I've used it a couple times on a 50a plug, and used it on a 30a plug (with a dogbone converter) at my sister-in-law's house, with no problem. At =my= house, however, it won't work. It's showing an E-1, reverse polarity, in L-2; L-1 shows no errors. I spoke with PI's tech support and they said to start by checking the dogbone to be sure that it's wired correctly and it's not breaking down. Can't remember the brand, but I'm pretty sure I got it at Walmart. I know it's =not= Camco. It works just fine when the shore cord is plugged into it and into the 30a plug. If the dogbone is correct, he said to then check the plug at my house. It was installed by a commercial electrician who =is= an RVer and has installed multiple RV plugs at his, and many others' houses, so I'm trusting that it's not the plug.
Anyone have a similar experience?
Also, I checked the paper manual and checked PI's web site for a complete display code list and all they have is the error code list; the user is left to figure out that L-1 is leg 1 and OA is zero amps (or whatever it shows), 60H is 60 hz, etc. I said that it'd probably take one of the junior IT techs to create a full "code page" and he agreed with me, and said that he's been telling management that this would be a good thing, for many years.

Can you find another dog bone from family or a friend and try it?
I would also pull the cover on the house and just check, mistakes are made. I just had an electrician here for a 100amp GFI that kept tripping,he checked and said bad GFI. Bought a new one 75 miles from home none available in town. (joys of small town living) Replaced & turned on power, new tripped immediately, more tracing and it turned out to be a bad hot tub heater, I have a spare 100 amp now.

Just thinking out loud of a way to isolate the error?
Is it possible it is displaying the error code due to a reverse polarity somewhere in your house?
Assuming the Dog bone is good and your receptacle is wired correctly & also assuming that it is a dedicated circuit?
What if you turned off every breaker except the Main & the one for the circuit your plugged into?
Do you still have the error code?
If (No) then turn on each breaker one at a time till you find the circuit with the issue.
If (yes) the error code remains with all other breakers off then the issue has to be the dog-bone or the receptacle wiring.

Brother has one that came with his Reflection, I do believe. I'll see if I can snag that and give it a try. In the mean time, I've texted my electrician about it and will see what he says. Lyle |

I'm not an electrician, nor have I slept at a Holiday Inn recently, so I can't see how =house= wiring could affect a plug that's wired directly into the panel. I =do= plan on having the 30a changed to a 50a later this year, so it'll likely be a moot point at that time. :-) Lyle |

I definitely agree with Edd505's suggestion!

The variable here is the 30A outlet, if it all worked at your sis in law, then I would check your outlet for proper wiring- follow the diagram.  |

On a 30 to 50 adapter, yes, that's what mine does.

If the EMS doesn't work there, I'll assume that the dogbone's bad. It'll, hopefully, be a moot point for both places in the near future. This weekend, my electrician friend is replacing my 30a plug with a 50a plug and I'm trying to get someone up north to replace hers as part of our "rent". :-) Lyle |

You're welcome, that will be a good test. I don't trust those adapters, even the name brand ones.

UPDATE: Took the rig up to sister-in-law's place and was getting the same error. Moot point, as I now have a 50a plug at my house and am paying to have one installed at sister-in-law's place. I =have= asked my brother to bring his 30/50 adapter home to see if that one will give the same error. Only down side is besides paying for the 2 boxes, I now have to buy a 50/30 adapter to keep at the house in case someone with a 30a plug wants to plug in.  Lyle |
