1. The voltage environment used is different. The European power cord is used at 220V, and the US power cord usually works at 110V.
2. The cross-section of the core of the US 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 US-standard power cord is low, the current passing through is larger, which is the core of the US-standard power cord relative to the European-standard power cord. The reason for the thicker section.
3. Specifications are expressed in different ways. The specification of the European power cord is expressed as: the number of cores x the cross-sectional area of the conductor, for example, 3x0.75mm?, the American power cord is usually expressed in AWG, for example, 3/C 18AWG.
4, the core color is different. The core color of the European power cord is usually two cores: brown (live wire), blue (neutral wire), three cores: brown (live wire), blue (neutral wire), and yellow-green (ground wire). The core color of the US power cord is usually two cores: black (live wire), white (neutral wire), three cores: black (live wire), white (neutral wire), and green (ground wire).
5, the certification is different. European power cords use VDE certification standards, and power cords with VDE certification can be sold in the EU. The US-standard power cord uses the UL certification standard, and the power cord with UL certification can be sold in the Americas.
