Usually you only see the rib on two wire cords. Yes this is the wire that gets connected to the silver screw on the plug end. On a three wire cord the inner wires are usually colour code identified. Black to the brass coloured screw, white to the silver coloured screw and green to the green coloured screw which is the ground connection.

Why is a red colored wire in a 120 volt circuit and what does it do?
It is used as a hot wire. <<>> In a three conductor cable set the third wire colour is red. In home wiring a three wire cable is used in a couple of locations. If the circuit involves a three way switching circuit, the cable between the two light junction boxes is fed with a three wire cable. Check the Internet for three way lighting connections. The other location a three wire cable is used is in split circuitry. Your kitchen counter receptacles use this method of wiring. The tie bar in the receptacle is removed on the hot (brass colour) side of the receptacle and the red wire is connected to the top brass screw and the black wire is then connected to the bottom brass screw of the receptacle. The white wire, as always, is connected to the silver coloured screw of the receptacle. Another example of using a three wire cable is to take two circuits from the distribution panel to two separate circuits on the other side of the house instead of running two, two wire circuits. The three wire cable is terminated in a junction box and two two wire circuits are feed from this junction box to the circuits that require power. The two two wire circuits will use the white wire of the three wire cable as a common neutral.
When wiring a house do you have to use the black wire as the hot wire?
No, there are different occasions when the red of a three wire cable gets used as a hot wire. There also times when the white wire gets used as a hot but has to be re identified as a hot with marking tape. When wiring baseboard heaters the cable used is red and black with no white wire in the set.
How do you wire a three wire 220v for dryer White to white but where does black and ground go?
If the cable you are trying to connect the dryer up to only has a white, black and ground wire, then the dryer is not going to work. The cable needs to be a three wire, the ground wire is never counted when discussing house wiring. Open up the electrical access panel on the back of the dryer. You will see a terminal block. A red and black and white connect to this terminal strip. The "hot" wires are connected to the outside terminals. The neutral (white) wire will be in the center. Connect the ground wire to the frame of the dryer. It is very important that this ground wire be connected as this is the wire that carries the fault current to trip the breaker should a fault arise.
Which wire is live on American cable white or black?
black
What color is the hot leg of 12 2 120 volt residential circuit?
Answer for USA, Canada and countries running a 60 Hz supply service.There should be a clarification of what a three wire cable is. A three wire cable consists of three main wires and a bare ground wire. The wire colours are, red, black and white. In normal circumstances the red and black wires are used as "hot" conductors. The white in this cable set is usually used as a neutral.Two commonly used procedures for a three wire cable in home wiring are for kitchen counter split receptacles and the other is for the traveler cable connection between three way switching. Also in home wiring, larger three wire cables are used for the range and dryer connections.In larger square foot homes, circuits that are right across the home from the distribution panel are fed with three wire cables. This allows two circuits to be connected to the one cable much like the kitchen counter receptacles.Now if your definition of a three wire cable includes counting the ground wire, the electrical terminology of this cable is a two wire. In a two wire cable the black conductor is the "hot" wire.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.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

How can you tell if you have a 4 wire cable installed with a 3 prong outlet?
What you term as a four wire cable is known as a three wire cable in the electrical trade. The ground wire is not counted in the cable set as it is not a current carrying conductor. Turn the power off to the circuit in question. Remove the three prong outlet from the junction box. If you see a red, black, white and bare ground then you have a three wire cable feeding the receptacle. If this is what you see and the purpose of this question is to see if it can be changed to utilize a new four blade recepticle then the answer is yes.

What are the colors of the conductors in nonmetallic sheathed cable for two wire cable?
The wire conductor colors in a non metallic sheathed cable are black, red, white, and a bare copper.
How to connect ipod nano with windows 2000?
by plugging the white wire with the usb cable to the usb cable slot. Then you plug the other side of the white wire into your ipod then it should say connected on the screen
What are the color codes on 240 volt 3 wire?
In North America the cable colour coding is Red and Black, usually used for the current carrying conductors. The third wire is White and it is used as the neutral on a three wire electrical circuit.
Where can one purchase wire and cable?
AWC Wire, wireandcabletogo, and graingerwire are three large suppliers of various types of wire and cable as well as other various types of industrial materials.

How do you connect a 230 volt outlets using a neutral white wire?
I am taking this question to mean that you are making an installation using two wire cable that has a black and white in it. In this situation the white is not called a neutral. At the distribution panel end the white wire does not connect to the neutral bar. It will go to one side of a two pole breaker. the other side of the breaker will connect to the black wire of the cable. On the 230 volt receptacle end the two wires will connect to either side of the receptacle. Make sure that the cable wiring is rated to take the amperage that your plug-in device will draw. The last thing to do is identify the white wire as a "hot" current carrying conductor. This is done by placing black tape around the white wire. This is done at both ends of the cables white wire. This is done to ensure in the future that is someone else works on the circuit they will know that the wire is not a neutral conductor.In the market place there is a new cable that has no white wire in it. This cable is used for wiring baseboard heaters and has a different colour jacket to identify the type of cable it is. The internal wiring colours are black and red. This wire is used for all 230 volt circuits.
