There are often many customers who don’t know much about the difference between the European standard power cord plug and the American standard power cord plug. So in order to answer everyone’s doubts, the editor Jun Jian below will tell you in detail about the voltage of the two. The difference between the core and other aspects.
1. The voltage environment used is different. European power cords are used at 220V, while American power cords usually work at 110V.
2. The core cross-section of the American power cord is thicker than that of the European power cord. According to P=UI (P is power, U is voltage, I is current), because the working voltage of the American power cord is low, the current passing through is greater. This is the core of the US power cord compared to the European power cord The reason for the thicker section.
3. The representation method of specifications is different. The specifications of European power cords are expressed as: number of cores x conductor cross-sectional area, for example: 3x0.75mm?, American power cords are usually expressed in AWG, for example: 3/C 18AWG.
4. The core colors are different. The core color of the European power cord is usually two cores: brown (live wire), blue (zero wire), three cores: brown (live wire), blue (zero wire), yellow-green (ground wire). The core color of the American power cord is usually two cores: black (live wire), white (zero wire), three cores: black (live wire), white (zero wire), and green (ground wire).
5. Different certifications. European power cords use VDE certification standards, and power cords with VDE certification can be bought and sold in the EU. U.S. power cords use UL certification standards, and UL-certified power cords can be sold in the Americas.
