I also found a link to the Progressive Dynamics website that discusses their EMS. I know there are a lot of folks using Honda EU2000s, are you all using a bonding plug? I am continuing to research this and it seems that at least some Honda EU2000s have a similar configuration to the Yamaha. Still above is how I would do it, do as you like NOTE Im longgggggggg retired as an electrical power distribution engineer and rusty on this and the latest codes so NO WARRANTY do as the manufacturer or NEC says if different them me. If it fed my home and I used a 2 pole transfer switch (2 hots if a 120/240, unswitched Neutral) I would use a Floating Neutral (NOT bonded to frame) and carry the equipment ground out to the gennys frame. If the genny fed my RV I would want a Bonded Neutral, but you do as you please. This has to do with Transfer Switch wiring. Maybe that's why the genset manufacturer isn't concerned the genset itself has a floating Neutral, because at the homes panel Neutral is bonded to ground there.Ī bit more technical, a genset which has a Neutral to Ground bond (often the gennys metal frame) is considered as a "Separately Derived Source" which is wired different then if not (floated) in which case its NOT a separate derived source. If the genset powers a homes panel that's a different situation, because it gets a Neutral to ground bond there. NOTE inside the RV panel, unlike a homes panel, the Ground Buss and Neutral Buss are NOT bonded but separate and electrically isolated and insulated, which is why I prefer the energy source, be it the parks utility power pedestal or normal utility (which have Neutral to Ground Bond at transformer and main panel) or genset have a bonded to ground Neutral. There's more to this story but nuff said for now. Its (safety equipment ground) like a bridge (wire) to nowhere. If its NOT bonded a ground fault to the Safety Equipment Grounding Conductor (which is bonded to outer metal cases of some tools and appliances) does NOT pass fault current and will NOT trip the breaker. Its easy to jump wire the Neutral and Ground together by using a male plug or other simple methods, I prefer a Bonded to Ground Neutral configuration myself. If your Genset has its Neutral FLOATED detection and surge devices don't know which end is up lol Seems like we discussed this in detail somewhere some time back, and there was a link describing which makes and models of portable gensets had FLOATING NEUTRALS and which had BONDED TO GROUND NEUTRALS. Any suggestions/recommendations would be greatly appreciated. It would be harder to get into the guts of the generator to see if the Red and Brown wires are reversed at that point. It would be fairly simple to switch the wires at outlet. Has anyone else encountered this with their generator? Same result plugging it directly into the generator outlet. I tested the outlets inside the trailer with one of the small circuit testers and both yellow lights and the red light are on indicating reverse polarity and open ground. The reverse polarity has me stumped as I looked at the wiring diagram for the generator and the Red wire is connected to the vertical/horizontal blade side of the outlet and the Brown wire is connected to the vertical blade side as shown in the wiring diagram. The faulty ground I can understand because the grounding system for the generator is not much. It passed the power through, but the screen is reading reverse polarity and faulty ground. Today for the first time ever, I plugged the Surge Guard 34730 into the generator. I have used my Yamaha 2400IS a number of times when dry camping and to charge the batteries.
