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.
In a standard three-pin plug, the hot wire (live wire) is typically connected to the right pin when looking at the plug with the pins facing away from you. The left pin is usually the neutral wire, while the top pin is the earth (ground) wire. However, it's important to check local wiring standards, as they can vary by country.
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.
You can convert a two-pin plug to a three-pin plug by purchasing a plug adapter that has a grounding prong. This adapter will allow you to safely connect your device with a three-pin outlet. It's important to ensure the adapter is properly rated for the voltage and amperage of your device to avoid any safety hazards.
To convert a 3-wire plug to a 2-wire plug, you would typically remove the ground wire from the circuit. This is not recommended for safety reasons as the grounding wire serves to protect against electrical shocks. It is safer to use a 3-to-2 prong adapter if you need to plug a 3-wire device into a 2-wire outlet.
The significance of the red, black, and green wires in a three-pin plug typically corresponds to their functionality. The red wire is usually the live wire, the black wire is the neutral wire, and the green wire is the earth wire. These colors help to identify and properly connect the wires for safe and correct electrical wiring.

The left pin is usually the neutral wire, while the top pin is the earth (ground) wire. However, it's important to check local wiring standards, as they can vary by country.
In a 2-pin plug, the wire that is not present is the grounding wire. This type of plug only has two prongs for the live and neutral wires, unlike a 3-pin plug that includes a grounding wire for added safety.
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.
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.

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.
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.

=== ====== === 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. === ===
