Hello Mike,
I have a new mobile food trailer with GFCI outlets that is powered by a new Honda EU7000is generator. The last part of my permit process was passing electrical inspection, which I failed. The inspector said the electric problem is the outlets in the trailer having reverse polarity. He used one of these (right) to test the outlets.
I had an electrician inspect the wiring and he says it’s the generator not being properly grounded. The place that sold me the generator is saying the generator works fine and has a floating ground/neutral. I am just trying to have my new generator and new trailer work together safely so I can pass inspection. Since everyone is on a different page on this issue, I figured I’d reach out to you. Any advice? —Thanks! LibbyÂ
Libby,
I suspect that all you need to do is plug in a G-N bonding plug at the generator. That will bond the generator’s floating neutral to chassis ground and correct the outlet readings. Make sure you plug this into the generator itself, NOT a receptacle in your trailer.
Here’s a short video on how it works.
Please let me know how it works out for you. Electrical inspectors are only trying to keep us safe, so he’s doing a good job so far. Â
Let’s play safe out there…. —Mike Sokol

Mike,
First off, thanks for all the great info on RV electrical issues.
I have a follow up about a G-N Bonding plug to make a set of generators work with a surge protector. I have two Yamaha EF2000iSv2 with the sidewinder cable. Neither is listed as primary power. How do I apply the plug; is there a way to determine if one is acting as primary power, or do I just select one generator and put the bonding plug in a 20 amp outlet, or do I put a bonding plug in both generators?
Thanks
