Hello everyone, I am writing this post to hopefully help others out with an open ground issue on an EMS or Surge Protector device when running a generator or paralleled generators to power your RV.
I followed this blog and inquired with the author about my parallel situation. This will solve an open ground on a Honda and Yamaha generator. Generator Ground-Neutral Bonding | No~Shock~Zone
- A pair of Honda EU2000i generators, one being the companion, that came with the parallel cables and rv adapter plug.
- Progressive Industries EMS-HW30c.
- 2014 Rockwood Roo 233s
With most small generators the power is not properly grounded and it will show on an outlet tester there is an open ground condition. I have read some information that states to drive a rod into the ground and attach a ground wire to the generator. That is great if you are in an area with ideal soil, and not in the desert or an extremely rocky area. I did some research and found that the solution to this problem is to create a plug where the Neutral and Ground are bonded. I am opting for this solution to my problem so I do not have to drive a ground rod and try to subsequently pry that ground rod out every time I go camping with my generators.
First I went to (insert local hardware chain here) to purchase an outlet tester and a NEMA 5-15 plug. I found a really nifty one with an LED "tester" built in, but I still got a separate tester as well to use elsewhere as well.
I used a 12 gauge wire to jump the neutral/white side with the ground/green side. Note: Neutral is the side that should be a bigger blade or goes into the bigger blade in a receptacle.
After installing the wire I put the plug back together. This is basically just a plug with nothing else attached to it from the outside. I tested it on both generators, and it worked great. For me, it did not matter what generator or plug I used the neutral-ground bonded plug in to solve my open ground condition on my EMS. However, I was told by Mike Sokol I may want to keep it on the companion genny.
- 1 NEMA 5-15 straight blade plug
- 3/4" of 12g solid core wire
Hope this helps those of you who keep getting an open ground fault on your EMS or Surge protector.

PS: thanks to Mike Sokol, Electrical Engineer and author of the No-Shock-Zone for walking me through this process and answering my questions in a timely manner.
