What Is The Standard For A Us Standard Power Cord Plug?

In daily life, power plugs are indispensable household building materials, but you may not know much about the relevant standards and selection precautions of power plugs. Do you know? In fact, the American standard power plug, as the name suggests, is the American standard power plug. You may ask again, what is the standard of the US Standard Power Cord plug?

At present, there are generally two types of voltages used for indoor electricity consumption in various countries, namely AC 100V~130V and AC 220~240V. 100V, 110-130V are classified as low-voltage, such as the voltage in the United States, Japan, etc., and on board, focusing on safety; 220-240V is called high-voltage, including 220V in China and 230V in the United Kingdom and most European countries, The focus is on energy conversion efficiency. In countries that use 220-230V voltage, there are also situations where 110-130V voltage is used, such as Sweden and Russia. American standard power plugs are used in the United States, Canada, Japan, Brazil, the Philippines, Thailand and other countries, and Taiwan, and are characterized by one round and two flats.

The American standard socket refers to a socket that is different from the three-item plugs commonly used in China. The live wire and the neutral wire are composed of two parallel plugs respectively. Instead of the two plugs forming a 120-degree angle with each other like the three domestic plugs. The domestic electricity voltage in the United States is generally AC120V/60Hz. Generally, there are three wiring connections on the socket, one is the live wire, the other is the neutral wire, and the other is the ground wire. There is no problem with the reverse connection of the live wire and the neutral wire because both positive and negative directions can form a loop. Just be careful not to connect the live wire to the ground wire interface. Whether it is the national standard, the American standard, or even the European standard, the power socket connection is the same. In fact, the national standard uses English letters, which are naturally the same as the American standard and the European standard. The live wire is represented by the English letter L, that is: line; the zero line is represented by the English letter N, that is: null; the ground wire is represented by the English letter E, that is: earth.
