What is the function of each pin in a 3 pin XLR PLUG?
Pin 1 = ground, Pin 2 = hot/plus, Pin 3 = cold/minus
Is it okay to use an adapter to change a three pin plug into a two pin plug?
No, it is not ok, it is potentially very dangerous because the two-wire cable has no earth with it. The earth wire is an important safety component that comes with a three-pin plug. An exception can be made for certain low-power appliances that have double insulation. This includes TV sets, radios, and table lights provided the mounting is plastic and not metal. These appliances are commonly sold with a twin-wire cable but often with a three-pin plug on the end of it. The three-pin plug in this case often has a plastic 'earth' pin and it is safe to replace it with a two-pin plug.
Why does in an electrical plug the earth pin is longer than other two...what is its main function?
The earth pin is called the equipment grounding conductor. The National Electric Code requires this conductor to be the first to make contact with the receptacle and the last to break contact with the receptacle, the way manufacturers comply with this requirement was to make the pin longer.
Can I plug my 2 prong Christmas light cord into a 3 prong extension cord?
UK answer only: Yes but you need a three-pin to two-pin adaptor. Alternatively fit a three-pin plug to the light and leave the earth pin disconnected. This can only be done if the lamp already has a two-wire cable fitted to it, anything else is potentially dangerous.
What does the earth pin do in an electric plug?

What is the function of 3 pin plug?
The 3 pin plug is used to connect (and eventually disconnect) various devices requiring an AC power supply to and from the main power supply.As the name suggests, the 3 pin plug consists of three pins :-Longer one, usually on the top for most standard plugs : is the earth [ E ]Left pin (Usually) : is the Line connection [ L ]Right pin (Usually) : is neutral [ N ]Next to the pins, on the plug, the three pins and their respective function is given by E, L and N.

Why is the earth pin in 3 plug the longest and thickest?
The term "earth pin" is generally a European term but in the US, the ground prong (same thing) is required to be "first make/last break." It must the the first terminal to make connection in the receptacle and the last terminal to break connection. The thickness is probably because the ground prong is often removed, either on purpose or by misuse.

Can MCB switches be used for Geysers?
Connect a good quality three pin, 15 amps plug the geyser cable with green wire connected to the earth terminal (thicker pin in the plug). If the geyser is to be fitted permanently at one location only, then it is advisable to connect it with a D.P. Switch to avoid burning of wires due to loose connections in three in plug and socket.

Why third pin is plastic in 3 pin plug?
Double-insulated electrical appliances, such as electric drills, only require two connections -a line and a neutral- to the supply. An earth (ground) connection is unnecessary. In the UK, all electric socket outlets have shutters that blank off the line and neutral terminals when there is no plug inserted. These shutters are operated by the earth pin of the plug. As double-insulated appliances don't require an earth connection, a plastic earth pin is moulded into the plug in order to open the socket shutters in place of a normal metallic earth pin.
What is the third prong in plug for?
On a British plug it is the earth pin connected to the earth wire. This is safety feature to stop electric shock

What pin on a power plug is the earth pin?
The third pin usually on the bottom is the pin that goes to the ground/earth.See Sources and Links below.AnswerIt really depends on what type you plug you are using. From your use of the word. 'earth' (rather than 'ground'), you may be referring to the plugs used in the UK, Ireland, and places like Malta, Cyprus, and the Gulf States? If so, then the earth pin is the longest of the three, and located at the top of the plug. Some European plugs don't use an earth pin at all -in Germany, for example, they use a pair of contacts located in the moulded recesses located on each side of the plug.
