Rare insults

We have a standard it’s called Type-F aka Schuko. It’s cross compatible with the French plug and socket. Though a Danish three prong plug doesn't fit in a Schuko socket but a Schuko plug does fit in a Danish socket. And in Italy it’s standard to install sockets that accept both Schuko and Type-L. Also type-C plugs aka Europlug (two prong, no grounding) are accepted in every European country except Ireland and UK.
