A few days ago I found this weird 3ph socket that had been sitting around in a box for about a year and decided to snap a few pictures.
Originally I found it in a house soon to be demolished that originally belonged to an architect and General Contractor. The room I found it in must have been some mixture of work shop and storage, I don't have the slightest idea what exactly they were doing there.
It is only 3ph+earth, 16A 380V, wired with 1.5mm2, and you can see how tight the connections were ;-)
The casing is made of die-cast aluminum I guess and it seems to be made in Austria since the only marking (aside of a brand logo I don't recognise) is ÖVE Austria.
I have NEVER seen anything like that!
