Trying to use a second-hand oven (bought in France) but it has this strange plug I've never seen before:
The wall sockets in the kitchen are just the usual EU one:
I searched the hardware store for an adapter, but could only find the inverse direction. And if I search for "four monophase adaptateur" ("four" is oven in French) then I also only see pictures of adapters going the other direction.
What is the plug? Is there such thing as an adapter to convert to a normal socket, or some practical reason why this only possible in the inverse?
If there is no such adapter, what will be involved to get this oven working - will it be as simple as wiring up the correct socket into the wall, or there may be more involved?
