MarkC Posted January 10, 2022 Share Posted January 10, 2022 Ordered a OTT and will be delivered Sept. with lithium battery package. I've been reading about the neutral ground plug and not sure how it works yet...only that I need one. Looking at the Honda e2200I companion generator...it has 1ea, 125v and 1ea, 30v receptacle. I plug the neutral ground plug into the 125v and the 30amp into the trailer. Correct, so far? My question is...what if I want to run a 125v tool at the generator while hooked up this way? Can I plug a Y into the 125v receptacle, plug the neutral ground plug into one leg of the Y and the tool cord into the other side of the Y. Does that allow the neutral ground plug to still do what its suppose to do? Or should I disconnect the 30 side from trailer first? Not sure why Honda only put one 125v receptacle on this unit as it has two on the E2200I regular unit. Must have to do with amp/volts. Link to comment Share on other sites More sharing options...
Ray Kimsey Posted January 10, 2022 Share Posted January 10, 2022 Yes you can put a "Y" plug in the generator and hook the ground plug into one of the two receptacles and then the tool in the other. 2019 Ram 1500 5.7L V8, 3.92 axle ratio - 2020 LEll - Hull676 Link to comment Share on other sites More sharing options...
Moderators SeaDawg Posted January 10, 2022 Moderators Share Posted January 10, 2022 Just get the Honda 2200i, save the $100 or $200, and use the 30 to 15 adapter for the trailer. If my memory serves, you still only get roughly 15 to 20 amps from the 30 amp plug, from the companion, unless you've linked it to a running 2200 with the parallel cable. It's something like 1800 or 1900 running watts, 2200 peak, so math says something like max 16 to 17 amps, running.

Moderators mossemi Posted January 11, 2022 Moderators Share Posted January 11, 2022 I agree with and adding to SeaDawg's comments. These spec's are for the EU2200i and the EU2200i Companion and they are identical except for the equipped output plugs.

Moderators SeaDawg Posted January 11, 2022 Moderators Share Posted January 11, 2022 We have two generators. The little Honda 1000 that's been our BFF for 14 seasons, and a Westinghouse 2500, 2200 running watts. We disconnect the trailer after charging, but I wouldn't run a big saw or our air compressor while the trailer was plugged into the Westinghouse. We have charged makita batteries at the same time as charging the trailer. The Honda won't run much, at 1000 watts, but it's great for charging our 2 agm batteries, only. 1 2008 Ram 1500 4 × 4 2008 Oliver Elite, Hull #12 Florida and Western North Carolina, or wherever the truck goes.... 400 watts solar.

Moderators SeaDawg Posted January 11, 2022 Moderators Share Posted January 11, 2022 One more thing. Your newer trailers have a device (ems) (probably progressive dynamics) protecting you from open grounds. That's why you need the neutral grounding plug. Most quality inverter generators (Honda, yamahs, and many others), use a floating ground, and it will trip out your protective device, without the neutral grounding plug . I know this sounds complicated, but it really isn't. It just is what it is. Buy the neutral grounding plug (maybe $15), or make one, use it when you plug in the trailer, and life is good. You don't have to understand all the electron magic. Just have the right bits. 5 2008 Ram 1500 4 × 4 2008 Oliver Elite, Hull #12 Florida and Western North Carolina, or wherever the truck goes.... 400 watts solar. DC compressor fridge.

MarkC Posted January 11, 2022 Author Share Posted January 11, 2022 Thanks for your info. Didn’t realize both Honda units put out the same amps. I probably would have purchased the companion model. Thanks again! Link to comment Share on other sites More sharing options...
