3000W Chinese Gensets Info.

I am unhappy with this unit and I have a question for professor or anyone who may know. This is my situation:

I wanted this unit because it was said that the Jing Dong "Homier" units will run full power to both of the only two 110V outlets on this unit without modification. But what I received is not a Jing Dong eventhough the picture in the auction is identical to the Blue JD unit. My unit is almost identical but I have a different breaker on mine from the JD Homier unit. I cannot run one of the heavy load items which I wanted to use with this Genset which is in addition to camping related items.

This is my problem >>>>> The heavy load item is a Thermal Dynamics 110V 20Amp plasma cutter. When I try to use the plasma cutter, the voltage meter on the genset falls to about 90 volts and the plasma cutter will shut off everytime. I contacted the manufacturer of this plasma cutter and they said many people use these plasma cutters on a generator. I was told it should be no problem with my rated 2800watt genset but this is not the case.

***** This is my question to the professor or anyone who may know how to answer this, Is it possible to rewire a 110V two outlet genset so it will supply full power to both of the two only existing outlets on a unit of this type?? This unit only has two 25Amp 110Volt outlets.

While it is possible that your unit has split outlets, it is unlikely. Most 110 only units I have encountered have parallel connected coils. Still, you need to perform one (or both) of the following tests to determine the wiring design. Once you perform the tests, write back and let me (us) know the results.

You will need a portable multimeter set to read AC voltage. Select a voltage scale that will allow you to read up to 250 volts AC.

Start the generator.

Place one of the multimeter probe tips into the SHORT slot on one of the 110 outlets. It does not matter if the lead is black or red.

Place the other meter probe tip into the remaining SHORT slot on the other part of the 110 outlet.

If your voltage reading is 220 or higher, you have series connected coils in the generator and can only draw 1/2 of the total wattage from a single outlet.

If your voltage reading is zero volts your coils are parallel connected and you should be able to draw full wattage from either 110 outlet.

Be sure to "wiggle" the probes around inside the outlet to assure that you have made contact with the internal metal pins. Obviously, if you do not make contact a false zero reading might be obtained.

ALTERNATE TESTING METHOD:

Open the generator front panel so as to expose the wiring on the back of the outlet (generator off, of course).

Look at the back of the duplex outlet where the GOLD screws are located. On the side of the outlet, between the GOLD screws is a metal tab that normally connects the two together. If the tab is intact, you should have parallel coils and full power to any 110 outlet.

If the tab is broken out so that there is no electrical connection between the two halves of the duplex outlet on the gold screw side, you most likely have series connected coils and will only be able to draw 1/2 of the total wattage from a single outlet.

Let me know what you find......
