Ok, long talk, short conclusion, our "light duty 3ph plug" is widely known as Perilex plug, rated for 16A. I saw the old "SEMKO 17" plugs being referred to as "widow makers" or "death plugs" in a german newsgroup (they were phased out in Germany in the early 80ies), Perilex plugs are still legal. Is it correct that SEMKO 17 plugs only had 3ph + PE? I always thought they were 3ph + N.
