Update: Finally someone has manufactured an affordable true 30 Amp parallel kit (around $60):amzn.to/2o5LWtB
KEEP YOUR HONDA FROM BEING STOLEN: amzn.to/2um7Eb0
To save time and hassle, I recommend buying the ( amzn.to/1Tav3H0 ) Honda parallel cable set and cutting it instead of buying the wire separately and banana plugs. It will save you $20 to do it the way I show, but it will just take a little more time.
Safety Banana Plug ends: (about $25 @ mouser)
565-6729-0 (black) 565-6729-2 (red)
6729-0 6729-2
Pomona Test Plugs & Test Jacks
R/A BANANA PLG BLK
US HTS: 8536698000 ECCN:EAR99 COO:US
You could also use these safety banana plugs: 125037 silvertronic
They are about $2.50 each and come in 5 colors.
Flexible 12 awg wire/cord is called "SO" wire or SOOW, SOEW, etc (about $4)
PUSH BUTTON CIRCUIT BREAKER 30A was purchased off($5) amzn.to/1Qi0bOX
Plastic outlet box/cover is from my local home improvement center.(about $1)
Cable holders are from my local home improvement center.(about $1)
RV plug adapter is (about $9) amzn.to/1Qi0ERb
Wire 3 HONDA generators together:
I assume you want to use this for your motorhome or trailer. You wire it the exact same way I did in the video, but use 3 sets of wires instead of 2 into the circuit breaker. Then from the circuit breaker you take a 2 lines off, one to each opposing side of the 50amp RV 120/240 plug. BUT this is not 240v compatible. This is strictly 50amps of 120V power. So if your plugging your RV into it you CAN NOT run appliances that use 240V like a dryer. You can run all your 120v appliances like dual AC units, fridge, tv's, microwave etc. On the 50 amp RV plug, the round is ground(green/bare), opposite that is the neutral(green) and the other two that are opposite each other share the 120v load(blacks)
You could also use this kit amzn.to/1TauRYp but you'll also need the adapter: amzn.to/1QhYUr9

Thanks - you have saved me a huge trip - minimum three days and over the price of a new genset! I will buy the Canadian units, have a warranty, and build some kind of parallel system similar to what you have. I appreciate that you have taken the trouble to look into this so well, and to put up a video of how you built your kit. It is well thought out and easy to follow. All the best!
-
Wow. Thanks for the time and effort you put into this. Not only the hardware to do it, but the video editing to boot!
-
I have a few links to various parts in the video description along with a brand new parallel kit that will give you full capacity out of your generators for barely more than I built this one for.
-
Yes you can. These little banana plugs connect directly to the regular plugs internally. I would try a couple plugs and try to find a really tight fitting one and use those for your setup.
-
Btw, I just looked up the shop manual online - you can download it for free. It confirms what you say - the parallel ports connect directly to the live and neutral wires. You are brilliant!

Good old Ebay... In the description below the video I show where I got everything and how much it was..

Cant wait to try this! The reason why its correct to use a 30 amp breaker is because the wire is rated at 30 amps. Even though the generator output is under 30 amps, if for some reason there was a short, the breaker protects the wire from catching fire and not the generator. The generator has its own protection against overloading and will turn off its output if it was overloaded.
-
Thanks for sharing, I will get a second Eu2000I and build my own parallel cable just in time for Hurricane season!
-
Cheers mate, I will definately keep you posted as my little Canada-in-particular problem sorts itself out! People should check out your other videos too. You have some great ideas for maintaining things. I love keeping old stuff running.

Thanks man. I bought 2 of the A-iPower SC2000i from Costco. The Yamaha made generators. I took them back twice. Getting them now I know that the parallel cables they come with melt or just ain't large enough gauge wire to hold up when running the AC on our camper. I wont use the factory cables this time. I was looking around on YouTube and found you. I'll look for the link for the banana plugs/connectors and make my own out of 10 gauge wire. I think that will do the trick and make a box like you did. Thanks!
-
you said it didn't matter which way you hook up the purchased parallel cables. I listened to, hooked them up. like you said and it toasted my EU1000. IT DOES MATTER HOW YOU HOOK THEM UP! Thanks alot doude!

Thank you for answering my questions! I have some more inquiries for you if you’re game? Awhile back I made the parallel cable box with the 30 amp push button breaker for two 2000i generators. The feed from that box was a female twist lock NEMA L14-30R 125/250v. The female twist locked into my panel power inlet male NEMA L14-30 125/250v- 4 prongs. Knowing that I would only energize one bus with 120volts, I bridged L1 and L2 to get 125 volts on both buses. I did this in order to avoid moving breakers around to one bus. It worked great. As you know one generator was stolen and I opted to upgrade and still parallel. Now I have two 3500 inverter generators that I found can use the Honda parallel cables to sync. In our last communication you said to change out the existing 30amp to a 50 amp push button breaker in the existing box. Q- I think I should change out the 30 amp cable and plug on the box to a 50 amp 125/250v #6-4 conductor cable with a 50 amp female twist lock? Q- If I am right my power inlet would be a twist lock male of the same pin and cable configuration going from there into my panel? Q- in the panel the existing generator lock separates a double pole 30 amp breaker. I imagine I should change that to a double pole 50 amp breaker and wire the new cable into it? Q- Last one. If this all sounds sound, would I have energize both buses or should I bridge L1 and L2 to do so?

Makes sense. Yeah, let me know if you do it and how it goes. The price on the banana plugs went up so I do suggest just splitting the basic Honda parallel cables.

I am revisiting this video. We had very long power outages with hurricane sandy. I have a yamaha generator that produces 2000 watts, not enough to run the well pump. But this generator, like yours, is a gas sipper (12 hours per gallon) with the idle up technology, and is so light that I like the idea of attaching two together for 4000 peak watts. I am pretty sure that would run the well pump. Yamaha sells the cable for about 90 dollars.

Your the man! We are in the Virgin Islands and after two hurricanes this information is gold! Thank you thank you
-
Great video! I would recommend a two gang Bell box for your splices and circuit breaker. Thanks for the info!
-
GREAT solution! Can you give me better shopping list and where to get these parts? PLEASE! I have the stock Honda cords and didnt know I was losing AMPS, ugh!
-
“I took them apart at the store.” 😂. So you’re the guy who’s opening the sealed boxes and messing with the merchandise! 😂. Great video. My next project.
-
Great Video, thanks. I have a Honda 2000i. I want to add another but they aren't made anymore. Mine is not among that serial numbers that Honda says is compatible with the 2200i for higher voltage parallel operation. Their cable is made to use the 30 amp box on the 2200i (you won't get the combined voltage). Do you have any idea if this type of setup would work for me since I wouldn't be using the connection on the generator?
-
Very neat. Never heard of anyone paralleling a non Honda with a Honda.
