Power cords:
A power cord is a wire that transmits power. In general, the method of current transmission is point-to-point transmission. According to the purpose, electrical wiring can be divided into AC wires. As a rule, AC wires are made of high-voltage AC wire. Officially, such a wire can be manufactured due to its high voltage only after obtaining a safety certificate according to a single standard. Basically, the DC line passes through low-voltage DC, so the safety requirements are not as strict as for the AC wire. However, for security reasons, countries still require a single safety certificate.
