richardbetsey Posted January 6, 2019 Report Share Posted January 6, 2019 I have a Honda EU2000i generator. When I try to use it with our New Horizons 5th wheel, it will not supply AC power to the trailer when I attach it to the Park AC power input on the trailer with the Camco 50 Amp to 15 Amp pigtail adapter. Along with this problem if I try to attach power to the trailer using thew adapter to a 20Amp ac GFI outlet It poips the GFI. If I pluge it into an AC outlet without a GFI everything works fine. Any ideas on how to get the Honda or a GFI outlet to work. Richard Clauser Quote Link to comment Share on other sites More sharing options...
GeorgiaHybrid Posted January 6, 2019 Report Share Posted January 6, 2019 (edited) You need to buy or make a plug that ties your neutral and ground wires together at the generator to get power thru your surge protector.

richardbetsey Posted January 6, 2019 Author Report Share Posted January 6, 2019 I tried that and all it did was trip the GFI on the Honda generator and on a 20 AMP AC outlet with a GFI immediately trip it. Quote Link to comment Share on other sites More sharing options...
GeorgiaHybrid Posted January 6, 2019 Report Share Posted January 6, 2019 Are you sure you have neutral and ground? It sounds like you have the hot leg and ground tied together on your plug. Quote Link to comment Share on other sites More sharing options...
DesertMiner Posted January 7, 2019 Report Share Posted January 7, 2019 Just bypass your EMS if your are using a generator. Quote Link to comment Share on other sites More sharing options...

It sounds like the Neutral and Ground wires are tied to the same point in the trailer panel. This is what's causing the GFCI to trip. Make sure the Neutral is connected to an insulated terminal, with only other neutrals connected to it. Quote Link to comment Share on other sites More sharing options...
NDBirdman Posted January 7, 2019 Report Share Posted January 7, 2019 Mine does the same. I checked for correct voltage/neutral, all good. I just turn off the EMI, works good for us. Just don't forget to turn it back on before connecting to shore power. Quote Link to comment Share on other sites More sharing options...
army Posted January 11, 2019 Report Share Posted January 11, 2019 Daryl is right. Could be a bonding screw in the panel that ties neutral to ground that needs to be removed. Quote Link to comment Share on other sites More sharing options...

Brad & Jacolyn Posted February 8, 2019 Report Share Posted February 8, 2019 When I need to use the generator I just bypass the EMS. Quote Link to comment Share on other sites More sharing options...
RickW Posted February 8, 2019 Report Share Posted February 8, 2019 For my Honda 3000i I just built a bonding plug. Took less than 5 minutes and cost less than $5. Like Brad said if your EMS has a bypass switch that will work too. I did the bonding plug route as I knew the one time I forget to turn the bypass off after using the generator, we would actually hookup to a bad power source and we get fried due to the EMS being in bypass.

Darryl&Rita Posted February 8, 2019 Report Share Posted February 8, 2019 So, did anyone read the original post? He's trying to figure out why a GFCI is tripping, not how to bypass an EMS, or trick it with a bonding plug. Quote Link to comment Share on other sites More sharing options...
GeorgiaHybrid Posted February 8, 2019 Report Share Posted February 8, 2019 The GFCI on the trailer is tripping because he is trying to back feed the panel thru that outlet. That is not what a GFCI outlet should allow and not where you supply power to your trailer. On popping the GFCI on the genset, something is wired wrong and assuming that Honda is more than likely correct and our finely assembled trailers are not, I would look at the wiring on the 50 amp plug on the trailer and inside the the EMS and breaker box to see if someone has crossed up the neutral and ground wires somewhere.

Randyretired Posted February 8, 2019 Report Share Posted February 8, 2019 (edited) Finding ground faults can be difficult but if it always pops a ground fault when the RV is plugged into one there is a problem. My 50 amp power source at my house is a ground fault protected circuit and occasionally when friends come by we find a problem. The fault is usually caused by the ground crossed with the neutral. Often times we find the electric water heater element has a fault but other things can cause it. Some just ignore the problem since it works without ground fault but I don't do that. My method of locating the problem is to disconnect all of the neutral wires in the RV breaker box and put them back one at a time. The bad circuit should trip the ground fault when it is connected. A load is required to make the ground fault trip so start with a breaker with something on and all of the rest off. This is somewhat technical and if you are not comfortable working on electric circuits you may want to hire it out. Another method is using a volt/ohm meter.

Carlos Posted February 10, 2019 Report Share Posted February 10, 2019 Wait, are you saying that you are using a male-to-male 15a household plug to put power INTO one of your outlets from the generator outlets? You should never use a male to male adapter! You should figure out why it won't supply power through the shore power connector. That should work. Test your adapters.
