1, the voltage environment used is different. The European regulation power line is used on the voltage of the 220V, and the gauge power line usually works on the voltage of the 110V.
The cross section of the 2 and the US regulation power line relative to the European regulation power line should be coarser. According to P=UI (P is power, U is voltage, I is current), because the operation voltage of American gauge power line is low, so the current passing through is bigger. That's why the power cord of the US gauge is thicker than that of the European standard power cord.
3. The representation of specifications is different. The specification of European gauge power line is as follows: the number of wire cores and the cross section area of X conductor, for example, 3x0.75mm? AWG is used to represent specifications, such as 3/C 18AWG.
4. The color of the core is different. The line core color of the European regulation power line is usually two cores: Brown (fire line), blue (zero line), three core: Brown (fire line), blue (zero line), yellow green (ground wire). The line core color of the US regulation power line is usually two cores: Black (fire line), white (zero line), three core: Black (fire line), white (zero line), green (ground wire).
5, the authentication is different. The European regulation power line is a VDE certification standard, and a VDE - certified power line can be bought and sold in the EU. The US regulation power line uses the UL certification standard, and the UL - certified power line can be bought and sold in the Americas.
