Understanding international cord regulations can be difficult. Part of this is due to the cord approval process. In power cords, the plugs, wires, and connectors are approved as separate components rather than as a whole cable. They each have unique rules and standards they must follow. However, while nations are required to use the same regulations for connectors, the approval standards vary from country to country, making it challenging to understand international cord regulations.
It may sound complicated, but it doesn’t have to be! In this guide, we examine international standards, different approvals and ratings, and how to adapt cables to various international requirements. Keep reading to learn more!
International Standards and Approvals
The IEC (International Electrotechnical Commission) is the global association that sets standards for electrical technology, including power cords and cord components. All countries must follow IEC regulations, however, there are many different approval agencies for individual countries. Although IEC standard connectors and power cords are used worldwide, their approval standards vary by country.
For example, Underwriter Laboratories (UL) is a North American approval agency that determines the approved ratings for North American power cords. While approval agencies can have their own ratings, they must comply with IEC international cord standards.
IEC Regulations for Power Cords
The IEC 60799 5.2.2 states, “The rated current of the plug or plug connector shall be not less than the rated current of the connector.” This means the connector cannot have a higher rating than the plug attached. While rarely an issue for standard or domestic cords, this can create compatibility issues when trying to use specific cables internationally.
There are situations where a power cord’s plug and wire may be approved while the connector is not. For example, many international power cords do not have approval for the IEC-60320-C19 connector. In North America, the C19 connector is rated up to 20A. However, that same connector is rated at only 16A in the United Kingdom. Not only are the ratings different, but because the C19 has a higher rating than the 13A UK plug, the IEC will not approve the connector. For the connector to be approved, the cord would require a plug rated no less than 16A.
Adapting to International Standards
There are a couple of options to make your power cables compatible with international cord regulations. Familiarize yourself with the international standards of the country you’re visiting. If your cord’s connector is not approved, you can either use an adapter or choose a cord with a higher-rated plug. Using a cord that is compatible with a country’s approved standards and IEC regulations is an easy way to safely avoid preventable risks like shock, fire, or damage to devices.
