Go to an Electric supply store and tell them it is a 20 amp plug. They should be able to get the correct plug.
I had this generator and had to adjust the prong to make it work.

How do i connect a three prong wire to a four prong plug for 240 volts


DO NOT DO THIS.

A 3 prong plug is L1 L2 and ground, a 4 pong plug has a neutral.
If you are backfeeding a dryer outlet it is dangerous. Generator N and G should be isolated unless it is a seperately derived source

How do I disconnect neutral bond on a dewalt generator


Please be careful, you need a neutral bond for the GFI outlets to work when you are using the generator as a mobile unit and grounding the generator with a ground rod or building. When you are merging with a building with a grounded system, simply remove the two neutral wires (White) at the generators internal terminals from the generator frame but keep them connected together and terminate connection.

Bonding on a generator questions


Q. If I was to keep the tie between ground and neutral in the generator during standby use, would I have to break the neutral tie coming into home from grid?



A. Never disconnect the neutral line as it enters your house. It is held very well at ground potential. Each transformer is grounded, and every home supplies ground as well. The neutral coming in is the reference to both live lines, and without it, anything connected to either live line could see up to 240VAC depending on what is across the other side. Install a proper transfer panel, and the neutral issue will be taken care of.

Q. Where would I ground the generator at this time in this situation?



A. The generator will be grounded through the extension cord plugging into the transfer panel. Your home should have one ground connection only, adding a ground rod at the generator could create other unwanted safety issues.

Q. At this time is it safe to run an extension cord off generator direct to power a drill for example?



A. Yes. The transfer panel will take care of any neutral and ground bonding issues, provided things are wired correctly.

Q. If I was to lift the neutral to ground in generator and tag generator as floating neutral, then would I leave neutral unbroken in service panel?



A. Yes. The common point for neutral and ground will be provided in the main electrical panel.

Q. Could I use the 15 amp outlets on generator safely in this position to run a drill outside? I see generators with floating neutral have a 15 amp duplex outlet on cabinet also. In this situation would I install a ground at the generator?



A. If you were connected to the house with the four conductor extension cord nothing else will be needed.

Q. If you have a floating neutral generator and use it in a stand alone mode, nothing to do with a home, do you place a ground rod down? What happens with the neutral and ground connections? What about a generator on a truck or trailer?



A. In stand alone use, you should connect to a ground rod. Neutral and ground should also be bonded in the generator. The easiest way to take care of this is with a dummy plug inserted into one of the duplex outlets or the twistlock outlet. Jumper ground and neutral in the plug. A generator on a truck or trailer will follow the same rules for neutral and ground bonding, ground rods, etc.

Q. If the generator is a grounded neutral type and you only run the two live lines to the house in an illegal back feed situation where main disconnect is off but neutral still connected will I have 120 volts available in house between each hot leg and the utility grid system neutral? Would someone get shocked if standing next to generator at that time and touched it creating a path from ground to the generator?



A. The only time I would consider backfeeding a house is if the main lines were torn down and laying on the ground. I did this once after Hurricane Juan caused a tree to tear the lines off a neighbors house. The lines were still connected at the pole and were live once commercial power was restored, but there was no possibility of the generator backfeeding to the street. It took almost two weeks before the power company could get them reconnected. We still turned off the main breaker and installed a padlock to prevent it from being turned back on. The house was totally isolated from the grid so I felt it safe to connect in this manner. The generator connected via a 20 amp two pole breaker in the main panel, and there was power available for everything in the house - well pump, electric stove, all lights, etc. Generator neutral was floating as described above. Power supply was limited, they were careful not to overload and trip the generator breaker.

Q. At the same time I went to a friends home and after killing the main breaker and all 240 breakers ran a 3 wire cord from the generator 240 volt outlet direct to his pump, now isolated from the house panel using both 120 volt lines and ground. I then ran a 12 gauge 20 amp extension cord from the generator duplex outlet to a double male pig tail and back fed a kitchen outlet so he could have lights in the house. 1/2 the house to be exact. This was also a grounded neutral generator but we didn't have a problem. I did however drive a ground rod at the generator.



A. I think you were lucky this time. Electricity can be potentially dangerous and can kill and burn if not used correctly. Double male plugs should never be used as invariably there is exposed 120V on one end. If you miswire one end you can send 120V onto the neutral. At best this will trip a circuit breaker, but not knowing what else is done, could easily create a lethal voltage on the chassis of certain equipment. It gets back to doing something properly or not doing it at all. Why run the risk of personal injury or death?

Want to add 240volt outlet to generator


You CANNOT do this, USA 240V is derived from a poly phase scenario, IE 120V line to neautral and 240V line to line, UK 240V is derived from 1 line to neutral it will not work unless you power a transformer

Ground the generated it's self. I had a similar problem after a storm once. First on the generater itself find a flat peice on the frame say by the motor. Sand in down to mettal. Put a self tapper screw in. Now get a 5' to 6' peice of 10 gauge bear copper wire. Attache it to the generator and shove the rest into the ground. Now it's grounded and It took care power surges when I did it. Hopefully this will help you.

I have a 10-2 ground wire and I want to use it on the generator, but it has 4 prongs. Besides the ground which two do I use?


You really need to use a 4 wire, one with red, black, white, and a ground. 10-2 will not work properly.

NO 20amp 120v power


you probably tripped a circuit breaker. Carefully push in all the circuit breakers, I bet that one of them will give slightly and power will be restored.

Sometimes the 20amp outlet is also a GFI outlet. You may need to reset the outlet itself if so equipped.

How do you convert the (2) 240 volt outlets to one twist lock connector on a coleman powermate maxa 5000 er genset


Make an Umbilical recepticle adapter. Buy the recepticle install the recepticle in a 4" electrical BOX on a plate with two manufactured 3 prong power cords plugging into the 2 outlets and terminating at the new Box twist lock recepticle you made.

My generator is not producing power runs fine does not make power


Could be several problems on the gen set itself. Check to see if there is a surge protection breaker or fuse, depending on age. Make sure all connecting wires are secure and switches are not set to 240v instead of 120v if you are trying to use outlets.

TWIST PLUG


go to an electric supply store and let them know it is a 20 amp plug. The big box stores only have a few selections of plugs
I had the same generator and had to modify the plug to make it fit correctly
