It is quite obvious that the UK std 220 V socket and plug for household applications is a bit big.
BUT.
It is very well made, all have an integral earth/ground pin and phase and neutral are always defined.
The std UK house has a quite large ( 100 A)incoming single phase 220 V supply and then there is a ring feeder going thru most rooms , thus the need for a fuse in each plug.
And some even has a little pilot light and a switch . Neat
So yes , I like the UK household electrical stuff, and wish that the rest of Europe had the same stuff.
But, the one phase supply is not to my liking.
