Assuming you mean the plug that goes into the receptacle . . . Its easy. Look at the plug. Attach the green wire to the cround (upside down U shaped). Attach the BLACK wire to the coppery connector. Attach the WHITE wire to the SILVERY connector. Attach plug cover securely. DONE. Go see this site for a better step-by-step explanation: http://www.hammerzone.com/archives/elect/accessories/ext_cord/end1/replace.htm
most dryer cords are flat and the connection on the dryer is split or the ground wire connection will be at a different height. The cord probably has black, red, and white wire. Black and red are hot and white is ground. It does not matter black and red or red and black, they are both hot. If the dryer is not marked it will be layed out so that the ground will be the center of the connection.
Generally *(Red , Blue) is connect with this symbol " L"/Line *(Black, Brown) is connect with this symbol "N"/Neutral *(Green, twist of Green & Yellow) is connect with Earth
Look closely. Almost all plugs indicate which is hot and which is neutral.
If there is a silver screw, that's neutral(white) and the brass screw will be "hot"(black).
If the plug screws are not different, look for writing on the base.
If you cannot find an indicator, get another plug.
Looking at the plug from the blade side directly on, you should see a larger blade (silver) on the right, smaller (brass) blade on the left and a U shaped ground blade on the bottom. The white wire connects under the right (silver) coloured screw, the black wire connects under the left (brass) coloured screw and the green wire under the green ground screw on the U shaped ground blade.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized

The 220 V should be between red and black wires and the ground connects to the ground prong on the plug.
If you are asking this question, then maybe you need an electrician.
Gold/black , white/silver.
My question is WHY did you replace a four prong dryer plug with a three prong! 220 volt Electric dryers require two hot legs, a neutral and a system ground wire. Sounds as though you shunted one of the hots or the neutral. You need to install a four prong plug of the same configuration and wire it exactly as the original.
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
If you are in north America, black and red go to the main prongs and white to the ground (round prong) . Black and red can be on either main prong.
Electrical plug hot wireThe smaller blade of the plug is the hot wire, but both wires are in a way hot. This is because you are working with alternating current. Alternating current changes its direction of flow 120 times a second in the United States. An electrical cord can have different plug types. The most popular are the two and three prong type with the three prong type the smaller straight piece is hot, the larger straight piece is called neutral and the round one is ground. With the two prong you don't have a ground.
I am guessing this is a 220-240 Volt plug. There is 220-240 V between Black and Red and the Green is ground.

South Africa uses 220-240V/50H 3-prong plugs that look like this: http://www.jjeac.com/UploadFiles/JJA-14%20South%20Africa%20plug.jpg
220 volt electricity 3 prong plug.
Three phases, one neutral and a GROUND
First you need to know that an electric dryer is almost always a 30 amp 220 Volt power supply. Most small welders require a 50 amp 220 volt power supply. Check your welder's power requirement. If it requires 50 amps, it'll never work correctly on 30 amp.The plug conversion is simple. The wire your dryer is powered by will have two "hot" legs, the red and black wires. These supply the 220 volt. Then it has a ground (bare copper or green conductor. And last it has a white wire, the neutral.Your 3 prong plug on your welder only requires the two "hot" legs and the ground wire. You shunt the neutral white wire with a wire nut.
I wouldn't advise it. Your pressure washer has a four conductor plug for a reason. It requires its two hot conductors providing 220 volts, a neutral which is likely being employed in a small circuit board or safety switch and an earth ground which is needed to provide path to ground for stray current and short circuit protection. Don't reinvent the wheel.
You can do it, on the four prong plug you have 2-hot(120v+120v=240v) 1-neutral 1-ground, on a 3-prong plug you have 2-hot and 1-neutral but no ground. on old electrical systems the neutral and ground bar were wired together. and that system worked fine,now they are isolated. There are no adaptors to do this you will have to change the oven pigtail with a four prong one and use 2-hots(black and red wires) and connect the neutral (white wire) to the green ground wire and attach the green wire to the metal body of the stove or change wall outlet to a four prong (although this is not recomended) you'll have to see if your panel has a isolated neutral bar. Best left to the pros as one wrong touch will give you a one way trip to the pearly gates. Hope this helps. p.s. I've found most ovens will have instructions on how to connect ether pigtail to it ,if its old hop on the net go to mfg.website put in model # usually there are installation manuals avalable.
A 220 oulet line carries two 110 vold lines and a ground wire. The outlet is shaped differently than the standard household (110) outlet, usually having at least one (plug-in) prong 90 deg to the other, sometines two of the prongs. This type is usually found in a utility room for dryers, most of which use 220 power.
