Question about Honda 6370C - Parallel Power Kit For EU3000i

2 Answers

Honda EU3000i is rated to put out 15A but won't

Honda EU3000i won't run my 15A electric log-splitter. It is rated to put out 15A but the power overload light comes on, and it won't send power to the log splitter. After browsing here, I'll next try turning OFF the eco-throttle setting. Any other suggestions? Will oil change, air filter clean-up, and such maintenance inprove performance?

    Thanks for the comments, jtlap.
    The log splitter works great on household 120v power. It's from Canadian Tire, and is brand new.
    I plugged it straight into the genny to avoid adding resistance with an extension cord, but still no workie.
    I have the manual, if ther are more specs that would help I can type them in.

    Hi joboo1. Thanks for helping me with my EU3000is honda generator and 15A electric log splitter. I got a chance to try your suggestions and was able to split wood using the locking plug.
    However, using the locking plug I see the red light (overload indicator) comes on for about 2 seconds and then goes out. The manual seems to indicate this is ok but what do you think?
    I'm planning to clean the air filter, change the oil, etc. as my genny is 2nd hand and I think maybe 5 years old. No idea how much run time.
    Anything else you'd recommend?
    Thanks again for your time and expertise.

    Hi, A 120v 15A log splitter? do you have more details on the log splitter? What kind of cord are using to the splitter ( how long). Did it ever work OK? Long distance troubleshooting is tough, more details will help.

If you attempt to use a 15 amp generator to power a 15 amp appliance you will have a big problem. Always plan to use no more than 80% of any power supply. You are currently trying to use the absolute maximum power this generator can supply, and it's probabally not rated for that load at continious use. Get a larger generator, or , a very sharp axe.

I hope this information was useful for you.

    More specs wont help, more power will. There's nothing wrong with your generator or the splitter, It's like this, the most you can use on a 20 amp circuit is 16 amps, and only 12 amps max on a 15. thats just the way it works.

Hi, Well, at this point I would try a couple of things depending on the age of the genset. Definitely turn off the eco throttle. The 120v duplex plug is rated at 20amps but varies with run speed so lets assume it is close and the specs a little loose. Change the plug to the 125v locking plug which at full speed is rated at 30 amps and see if it holds. The rest would be dependent on age . This genset has a 2 year residential warranty and if it is under I would have it repaired under the warranty. I would at the very least test it or have it tested to see what the overload is tripping out on. My best guess from here is the overload circuit board if everything runs correctly. We use this genset out in the field for bull testing equipment and haven't had a problem like this even with an extension, (we use the locking plug). As far as your overhaul, if the genset is running up to speed and doesn't bog down it is probably OK. If you hear any difference in speed at all when you plug something in, change the oil, filter and spark plug and check your carb settings. Good Luck, let me know what you find out, hope this Fixsya!

    Hi Jim, I think your splitter is pulling the max so the only other suggestion to squeeze out any more is to check the wire size from the splitter, if it is rated for 15 amp the wires size is probably a 12 gauge or less. Most appliances do not run at full faceplate rating all of the time, but it sounds like your splitter is running close, so a bigger wire size won't hurt and will even fit your locking plug a little better. If you have room from your splitter try a 10 gauge. Glad we at least got you going! Let me know how it works out for you! Thanks

I have generac c 5000 series, that is 5000 watts . can you give me the equivalent watts given into Kva?


This is the formula The conversion of W to KVA is governed by the equation KVA=W/(1000*PF)

For example 1500W/(1000*0.83) = 1.8 kVA (assuming a power factor of 0.83)
Thanks for using FixYa and for the great rating.

Wont run off 1/2 choke

I had a problem with a honda generator that would only run on full choke. I removed the carburetor and cleaned the main jet with a wire and carb spray. Problem solved. Fuel stabilizer should be used with todays gas mixtures that have ethanol in them. Hope this helps.

Honda EU30001 generator causes erratic pellet stove operation.

Ok Motors and the like generally DO NOT really go all that well from a generator, what load does the Stove use?, You must add up the cumlitive "Wattages" of ALL things connected, see your generator is about 3000 Watts, 3KW, How much "headroom" is there between the two? Whats supplied versus whats being used? Purely inductive loads, like Motors etc, are less responsive than electronic loads. I suspect that your generator is NOT providing enough current to the Stove, especially when "Other" things are connected. also. Look, if the, any, generator is 3000 Watts really you should only load it up to a couple of KW's, 2.5KW being about maximum. To do what you are doing would require, IMHO, at least, 5KW, to get the "Headroom" of current drawn over current able to be delivered by the generator. Also inductive loads loose heaps of power and actually cause a higher draw. So that your answer, you must use it well, inside it's rating, not right up to the limit.
