its a 230V 16A outlet, and if not RCD protected that metal could get quite hot with a short circuit before it opens the breaker

It will get voltage to the cable. It will not convert the voltage between 110 and 220.
(Of course it will also be a shock and fire danger to everyone in the building and you should wear electrically safe gloves to construct it, but it will get voltage to the wires as shown.)
Edit: another safety concern. this may reverse polarity which won't matter for some things but could mean heating elements in hair dryers and toasters for example may have live voltage on them instead of being connected to a neutral line when powered off.
WTF
HONESTLY WHY IS IT THAT EVERY TIME I OPEN THIS APP I GET IMAGERY LIKE THIS THAT MAKES EVERY HERTZ HURT
I’m being slightly hyperbolic.
…but as someone who is nominally a sparky, not by much.

Won’t be needing that return ticket 🎫
