Stop! What...? Don't try to do that...!
Don't make a cable with the intention of plugging a generator into an outlet in your house, it is incredibly dangerous!
Power from your generator will back-feed into the power lines, posing a severe unexpected shock hazard to any line-workers who may be fixing the lines - the very same reason you are wanting to use your generator!
Plug your appliances directly into the outlets on your generator. If you want to power the outlets in your house from the generator you must do it right and install a proper 'generator transfer switch' at the main incoming breaker panel which is situated where the main electricity service cable comes into your house.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

You are wanting to power your RV with your generator The RV uses 30 amp 3 prong your generator plug that is 30 amp is 4 prong Can you do this?
Go to this site http://www.generatorjoe.net/html/nemaplugs.html and tell me what configurations you have and I might be able to help you.
If you can change a 4-wire to a 3-wire 240V outlet circuit then what was the purpose of having a 4-wire box in place to begin with?
== == You are not allowed to change a four-wire outlet to a three wire outlet.You can change a four wire cord to a three wire cord.That is VERY different! === === I have answered this question at least 6 times. The 4 wire plug has a neutral and the 3 does not. An untrained homeowner who does their own plumbing can flood the house with water or sewage, on the other hand electricity can kill instantly. I wouldn't want to gamble my family's lives on my incompetence. 3 wire plugs are old and outdated. Way back in the old days they didn't ground equipment so plugs didn't have a ground. (Remember the old 2 wire 110V outlets on houses built before the 50s?) A few people got killed so they decided to add a safety wire. It took them longer to catch on with heavy appliances, but eventually they did. That it what the fourth pin is. Since many homes still have the 3 wire plug it is allowed in older homes. New homes must use the new 4 wire plug. Changing your 4 wire cord to a 3 wire cord is the same as plugging a 3 wire 120V appliance into one of those 3 prong to two prong adapters they sell. Your appliance works now, but is ungrounded. Don't listen to anyone who says to replace the new up-to-code plug with an older plug. That is the same as replacing your 3 prong 120V outlets with old two prong outlets! Ignore anyone who tells you to do so, they think they know a lot more than they actually do. Buy a new cord. It is cheap and safer.

Are there 3 prong to 4 prong adapters for driers?
No, and adapters are not needed. What needs to be done in remove the old three blade dryer plug and install a new four blade cord on the dryer.Dryer plug three to fourInstructions should come with the new cord. Open up the electrical access panel on the back of the dryer. You will see a terminal block with three wires going into it from the plug cord assembly. A red and black and white are now connected to the terminal strip. Look at the position and colours of the existing 3 prong cord and how it is connected. Make a diagram. Coloured wires on the outside terminals white in the center. From the center wire terminal you will see a jumper strap that goes to the frame of the dryer. When installing the four prong plug this jumper is removed completely. The kit should have with it a grounding lug that connects to where the removed grounding strip attached to the frame of the dryer. This is the attachment point for the fourth green ground wire from the new dryer cord assembly.
What do the letters stand for on a 4 prong plug?
On a 240 volt outlet, such as a dryer outlet: G is Ground, W is Neutral, X and Y are the two Hot legs.
When wiring 4 prong plug for 220 has W X G and Y what goes into the X and Y?
On a 240 volt outlet, such as a dryer outlet: G is Ground, W is Neutral, X and Y are the two Hot legs.
Four prong generator male to a 4 prong female then go to a 110 volt house current?
I,m going to bypass the generator and plug into the house for my race car trailor. Once I pull the plug from the gewnerator I will have a four prong male need to plug into a for prong female then be able to plug into a house socket.
How do you connect a 4 prong generator twist and lock plug to a 3 prong travel trailer power cord?
Check Lowes and Home Depot they normally carry the adaptors
If your outlet is a 3 prong outlet can you hook up a 3 prong plug from your old stove to a new stove which has a 4 prong plug?
No you can not you will need to replace the plug with a 4 prong the same as the style of your oven and change your breaker to the correct Amp for your style of 4 prong plug

Where do you ground the extra wire when plugging a 4 prong wire into a three prong outlet for a dryer at?
It may be a 220 Dryer, and you will need a new outlet installed. There should be no extra wires when connecting the Power cord to the plug
How do you wire a three prong twist lock receptacle to a 4 prong male connector in 220V?
Buy a new receptacle that your plug fits in. You probably need one with a neutral so look for 125/240v.
If your generator has a 4-prong 240V 30A receptacle 8500W peak and your stick welder has a 3-prong 240V plug how do you make this work?
Before you follow any of these instructions, make certain that you check with the documetation that came with the generator, since I can't be certain of what your generator is doing. The following assumes that the generator provides 220 output and is NOT 3 phase. If it's 3 phase, all of the following is wrong and don't do this! In general, 220 circuits have 2 110 "leg's" which are nothing more than a center-tap into the 220 source. It can be a center tap on a transformer or a generator. The center tap is designated with a white wire, and the two "hot" lines are usually designated with either black or red. In the case of your generator, if it is not a 3 phase circuit, the 4th wire is probably green which is the universal indicator for a ground wire. To be safe, it is a good idea to ground the generator using a long, copper grounding rod that has been driven into the ground and using a good sized wire (typically #10 or larger) connect it to the generator at the grounding lug, again, see instructions that came with the generator. To make the welder work with the generator, you can "get by" connecting the white wire to the white of the generator or if you're using a plug connect it to the silver screw. The two black wires or the black and red wires are connected to the two brass colored screws. Whenever a ground wire is provided on a wire it should be connected to grounding screw of the plug. I hope this is enough information. If you have any questions, contact the manufacturer or a local electrician.
How do you make 4 prong male plug to 3 prong male plug?
This is something that should not be done. If this was to be done you would be omitting the ground which in point can make it unsafe. I recommend changing the female end of the system and making it a 4 prong.
What is the difference between a 4 prong dryer outlet and a 4 prong stove outlet?
The four blade dryer plug brings a separate ground wire from the machine to the electrical grounding system. The three blade dryer plug depended on the neutral wire of the plug to make this connection.
How do you wire a 4 prong trailer wiring plug?
If you are referring to a 4-wire flat trailer cord then; White=Ground, Brown=Marker/Tail, Yellow=Left turn, Green=Right turn.If not, see the answer to the Related Question shown below.
Do you have a picture of 4 prong electircal plug?
There is an illustration at the related link below.
Wiring circuit for 240V welder with 3 prong plug pulling 6-3 wire do you need to replace welder cable with a 4 lead cable-plug or can you avoid the white lead to wire a 3 prong outlet red-black-green?
It depends on the welder. If it doesn't need 120V you can just put a wire nut on the neutral and wire a 240V plug. If it needs 120/240V you need the 4 prong plug. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.
