pin having largest area of cross section will be ground pin as it will hve lower resistance , hence provide lower impedence path for ground fault currents.

Why you use three pin plug insted of two pin?
In an electrical socket, there are three holes. One is a hot wire, one is a neutral wire, and one is a ground wire. Usually, the hot wire is black. The neutral wire is white. And the ground wire is green. Motors usually have three pin plugs. Other items also have them. When a motor has a three pin plug, the body of the motor is attached to the ground. If a spark goes from the electrical wires to the body of the motor, it will go harmlessly to the ground and not hurt anyone. On a two pin plug, usually one pin is larger than the other. The larger pin goes to the neutral or white wire. It is also grounded. That way if there is an electrical short in the device, it should not electrocute the person using it.
3 wire to 2 wire plug?
You get a two wire plug!! You should never try to skip connecting the ground wire, the soul purpose of the ground is to create safety for you and others around you. the problem is that someone may assume that the ground is part of the wire since the plug is a three wire!! \You will have to skip the ground terminal on the plug. Usually plug has a green screw or wire, ground pin is longer than two other and round in shape.
How do you adapt a 3 prong German plug to fit into a 3 prong US 230 dryer outlet?
German appliances don't have three pinned plugs. The standards are the "Schoko" plug, which is a two pin plug with contacts on the side as a ground connection and the "Euro plug which is a two pin plug without a ground connection. There are adapters available at most good electrical stores.
How do you convert a two pin plug to a three pin plug?
You don't, in theory, because the ground wire is missing. But if you must, cut the end of and add the new three pin plug, the two flat pins are for the two wires, the round is for the ground that is missing. If something has only two wires,say a light fixture, adding a plug that has the three is useless because the ground wire is missing, so it does not become safer just because you added it. If the end is bad,then you get a plug end that comes apart and is made for adding to a wire, do not cut wire,add another plug end by splicing it together with electric tape.
What is the function of the live wire in a 3 pin plug?
A 'live' or 'hot' wire is a wire that is connected to a power source. This wire supplies voltage to a load ( light bulb, hair dryer, etc.). When the load is also connected a neutral or another live wire this becomes a path for the flow of current (amps) known as a circuit.
How do you connect the 3 pin plug?
One pin for phase other pin for neutral and third one is for earth/ground wire. In India the right pin is for phase, left pin is for neutral and pin on top side is for ground wire. This third top side pin is slightly bigger and longer compared to phase and neutral pins.
Does a 4 wire plug for a dryer can be replaced with a 3 wire plug?
The fourth prong is a ground for the body of the dryer. The dryer will work fine with the 3 main ones. Building code requires the four wire plug now, but you can change it and the dryer will work. If you have a 4 plug outlet and a 3 wire cord, you can just change the cord and not use the second ground or connect to the the frame of the dryer.

Which wire is not present in a 2 pin plug?
The earth wire.
What is the purpose of a wire?
it is the brown wire in a three pin plug

Can you plug a 220 dryer in an 220 aircondition plug?
Probably not, the pin configuration of a 30A dryer plug should be different from a 15 or 20A A/C plug. The demand draw of a dryer is higher than that a A/C unit and would trip the 15 or 20A breaker. By putting a bigger breaker on the A/C circuit would not be a good idea either because the wire size to the A/C plug would then be under sized.
What pin on the plug to the AC outlet is the ground pin and what is its purpose?
The ground pin or earth pin is the uppermost pin on your plug. It's purpose is to provide a safety barrier between you and the supply in the event of an overload or in case of an accident.
Can you plug a four prong dryer into a three prong outlet or is there an adapter you should use?
=== ====== === Old practice [accepted by National Electrical Code requirements] allowed the frame [chassis] of dryer to be bonded to the neutral conductor by a link to provide ground. New NEC requirements call for separation of neutral and ground paths. In a new house, or if you install a new cable to feed the dryer, you would be required to run a wire with an insulated neutral and a ground wire [10/3 with ground - 4 wires]There are 2 possibilities:One is that there is actually a 4-wire cable feeding that outlet, in which case you CAN change the dryer outlet to a 4 wire type - you just have to put the right wires on the right terminals and make sure the ground is connected in the panel. [Even though we only used 3 wire outlets, most electricians I know had run 10/3 with a ground for dryers in case the unit got hard-wired, which used to be allowed.]The second possible answer is that you are allowed [unless your township or city doesn't allow it - always check with them first] to establish a ground-to-neutral link inside the dryer unit for the chassis ground and replace the 4-wire plug with a 3-wire plug. [See NEC Article 250.140] Answer Some dryers also have devices (such as lights and the timer) that run on 120 volts. These need a neutral that is separate from the protective ground.I got a new dryer yesterday... the plug on it has four prongs and my old one has three prongs. So can the old three prong plug be taken off my old dryer and be put onto the new dryer? I notice my old three prong plug is not color coded like the one on the new one. Also when I took the old dryer off and unplugged it, a green ground wire was still fixed to it (the old dryer), so how would I ground the new dryer being that it only has three prongs? Thanks in advance. === ===
