Re: 3000W Chinese Gensets Info.
To Curly2001: You were asking about rewiring your Power Pro3500. I have one, and rewired according to posts on this thread. See pic: This schematic was created by another member of the forum. These reconnections were all done down at the generator head where they hook to a terminal strip. Very easy to do, and It made a lot of difference in the voltage drop when operating my A/C. Instead of dropping from 120v to 108v or so......it only drops down to about 116v. Tom310Views0likes0CommentsRe: 3000W Chinese Gensets Info.
Could you guys who have rewired the generator for full power let me know what voltage you have between neutral and ground with load and no load. I know that usually the neutral and ground lugs are connected together in a house panel, but I am a little dumb regarding generators. Thanks. Tom298Views0likes0CommentsRe: 3000W Chinese Gensets Info.
I forgot to comment on dubman's breaker question..... When you have a 220v circuit, you use both legs of 110v to power a device, and if that device needs 30amps to operate, it has to have 30amp flow trough both legs due to the fact that the legs are operating in a push pull type of interaction. So if a double pole breaker says 30 amp on it that means that 30 amps will flow through each leg. Hope I haven't confused everybody. Tom301Views0likes0CommentsRe: 3000W Chinese Gensets Info.
Little Bill I'm not sure about the elim. Usually when you have a 220v supply with only 3 wires, you have 2 110v wires and one ground wire. The reason this can work is that the two 110v legs are out of phase with each other and so they add.....in a push pull kind of reaction. In this case a neutral wire is not necessary. The neutral wire in other 220volt setups is actually carrying current from both legs of the 220v. to provide current flow. Since the current flow in a three wire setup is from one 110volt leg to the other 110volt leg a neutral is not needed(as I said redundantly before). The third wire of course is a ground for safety in case a hot wire gets loose and touches the frame of whatever its in. So to use only one leg of 110v from a 3 wire setup would require the addition of a neutral wire to carry the current. The safety ground wire is never to be used for carrying current. Luckily the Power pro has the 4 wire outlet. Tom275Views0likes0CommentsRe: 3000W Chinese Gensets Info.
Regarding the 220 outlet on my Power pro generator.....When you use an adapter like the 50 amp to 30 amp....you are only using one of the phases of the 220volts. A 220 volt supply has two hot legs(phases) and they are each 110volts(may be 120volts depending on the supply). So what you have is two 110 legs, one neutral wire, and one ground wire. The adapter I spoke of has a connector on one end which has 4 prongs and they correspond to the wires I mentioned in the previous sentence. On the other end of the short adapter cable is a plug with only 3 prongs which corresponds to one 110v leg, a neutral, and a ground. So you see, I am using 110 volts from the 220volt outlet which delivers 30amps and has the correct guage wire to handle that load. If you are snowed by all this, just get an electrician to make you a pigtail with the appropriate plugs on each end. Now about the Gen-turi.....I kind of crossed subjects in this thread when I talked about the home made gen-turi which I added to my Power pro(from Pep Boys). A search on Gen-turi will give you a wealth of info on this great addition. I should also add that my generator is mounted on the extendable bike platform which the new Cougar 5th wheels have in the rear. So the gen-turi is conveniently attached to my ladder on the back, and I have permanently mounted it to the ladder and the generator. No pictures yet, but I will try to get some soon.

I am tickled with my Power-pro generator. I just used a 50 amp to 30 amp converter pigtail....it has the 4 prong male 50 amp plug on one end and a female 3 prong RV plug on the other.....and I cut off the 4 prong plug and added the twist lock 220 plug that came with the genset. So I don't have any worries about not getting the maximum amps to the rv. The 220 plug is 30 amp. I also made a gen-turi which made the gen. even more quiet. I just followed the examples that others made in the forum. I used black plastic pipe from Lowes and a conduit ell. I spaced the ell with 1/2 " copper pipes placed at 120 degrees inside the black pipe....as someone else did in this forum. I just drilled a hole in the ell and the exhaust pipe of the gen. to pin the ell and allow for easy removal. The Power-pro exhaust pipe is only about 7/8 " so I used 1" conduit and 2" black pipe....it works perfectly. I don't feel that back pressure is a problem due to the small amount of exhaust from this engine. If your generator has a larger exhaust pipe of course you have to use larger pipe to your gen-turi. Anyway....I am thrilled at the info I have gotten from all of the rv forum members. It really helps when problems are encountered to have this resource to call upon.275Views0likes0Comments
