What is the difference between European and American power cords?

The voltage environment used is different

The European standard power cord is used on the voltage of 220V, and the American standard power cord usually works on the voltage of 110V.

Different in appearance

Compared with the European standard power cord, the core section of the American standard power cord is thicker. According to P=UI (P is power, U is voltage, and I is current), because the working voltage of the American standard power cord is low, the current passing through it is larger, which is the wire core of the American standard power cord relative to the European standard power cord The reason why the section should be thicker.

Specifications are expressed in different ways

The specification of the European Extension Power Cord is: the number of cores x the cross-sectional area of the conductor, for example: 3×0.75mm, and the American standard power cord is usually expressed in AWG, for example: 3/C 18AWG.

The color of the wire core is different

The core color of the European standard power cord is usually two cores: brown (live wire), blue (neutral wire); three cores: brown (live wire), blue (neutral wire), yellow-green (ground wire).The core color of USA type power cord is usually two cores: black (live wire), white (neutral wire); three cores: black (live wire), white (neutral wire), green (ground wire).

The certification is different

European power cords use the VDE certification standard, and power cords with VDE certification can be bought and sold in the European Union.

US Power Cords use UL certification standards, and power cords with UL certification can be bought and sold in America.
