Has anybody with a big rig had success plugging into a 15A GFCI? What steps do you take? I have had no luck at all. Tried reducing SHORE setting, Tried bypassing the Progressive EMS. The GFCI pops immediately. No problem with a non GFCI, but they are rare.

Can’t plug into a GFI outlet or it will do exactly what’s happening. Nothing you can do to make a GFI outlet work.

Here is information for house service to keep batteries all fully charged, all you need is 110 outlet.
GFI could be recognizing a problem in coach like electric elements leaking to their casings in a Gas refrigerator for instance.

Most likely your charger/inverter trips it. GFCI's and them don't work together......

I found this same problem with a GFI, but on a hunch I suspected a problem with the GFI. Replacement with a new one resolved the problem.

Open the 120V AC circuit Breaker that is for Fridge Electric element (or unplug fridge power cord)

Then try using the GFCI outlet

Had this problem at my son's house parked on the street.
0utside outlet on the porch was protected by a GFCI.
So I plugged into a garage outlet, no problem. We were there for 2 months. Try living with 15A that long. Luckily our A/C only uses 8A.
Finally ran a second long cord from the porch thru a RV window so we could run microwave, toaster, etc.

Check your power cords. I plug my 40' MH via 50a cord, 30a extensions, over 100' into a GFCI outlet on my front porch. Have done the same with our previous 5ver, 30a cords and 30a extensions, different GFCI, no problems. Check your cords. My 30a extension cords use twist-lock connectors like the ones used on construction generators. Blade-type connectors heat up and burn up, they are junk.

Have the same problem when my friend comes to visit with his rv. I just plug his coach in with an extension cord that doesnt have a ground prong. It doesnt pop the gfi then. I have to do the same with my block heater on my backhoe. It will pop the gfi every time if I use an extension cord with a ground on it. I know I will get taken to task for telling you this, but gfi s are a pain in the butt most times. We have worked on boathouses, and dropped the end of the cord in the lake by accident, and it didnt trip the gfi. Next time, one drop of rain and all the gfi s are tripping.

RVs and gfci circuits often don't get along. Best to just use a non gfci outlet.

Scottybdivin · 12-03-2017, 05:40 PM

OK. Sounds like I'm not alone. I don't think there is anything wrong with my coach. I have a residential fridge (1.1A @ 120V). My 110V electric elements are off on the Hydro-hot. I set SHORE to 15A and have even tried going down to 5A. I use the 50 A cord all the way to the outlet. I have tried multiple adapters. As soon as I plug it in, the GFCI trips. May have to re-think this. Non GFCI, no problem. I have camped on 30A power many times. I may consider carrying an external battery charger and connecting it directly to the coach batteries, then running everything off the inverter.

Winniman, just for grins, I may try removing the ground prong on an adapter and see if works. Thanks.

Scotty, I wouldn’t ignore the issue. Maybe not your problem but my ‘05 HR would do this. It was fine with a regular outlet. Went through 3 transfer switches before blowing up a 50 amp pedestal.
Turns out the invertor/charger had a short and I had 115 volts on my neutral.
A mobile RV tech diagnosed it, Magnum replaced the faulty unit and all was well but please, don’t ignore the GFI issue. Could be a small or a big problem. Good luck with it. - Ron

I dont have this issue, even with a progressive industries surge protector. I put the shore setting to 10 amp, and reduced to a regular extension cord, then plug into the GFI at the storage facility.

No muss no fuss.

HMMM! I do have a new Magnum MHS 3012 (Hybrid) on the way, replacing my ME 3112 modified SW inverter. Maybe, we will see if that makes a difference once I get it installed.
