In the process of global harmonization, the USA and Canada will adopt the IEC 60320 standard for device plugs with minor deviations.
The IEC 60320 appliance plug standard represents a worldwide valid standard. Global standards make it easy for both component and device manufacturers to evaluate guaranteed suitable sockets and plugs. So you can be sure that the plug from the European manufacturer A will also work without problems with the socket from the Asian supplier B. Beyond that the safety is examined against electrical impact just like against fire.
