   The plug-in system defined in the standard for 250 V / 440 V alternating voltage at 50 Hz is structured to be “hierarchically downward compatible”. [3] This means that sockets designed for 16 amps also accept plugs for 10 amps, but not the other way around, and that 2- or 3-pole (single-phase) plugs can also be used with 5-pole (three-phase ...
