Fair point on BS 1363 not being EU, and about UK electricians not being incompetent (I actually didn't know they were careful unlike the continent -- that's just one of those things that once you have to deal with the insanity that is continental Europe, it doesn't really much matter what else is out there).

But my point about electrocution risk is that 240V is not twice as dangerous as 120V. It's actually much, much worse. And 480V is worse still. We used to say that screwing up 120V will hurt you, 240V will kill you, and 480V will kill you, start your corpse on fire, and blind everyone around you. So the design requirements for all 240V class plugs are much more important.

This one is a real problem in the US because there is a standard, it is a good standard, parts are made and tested to the standard, and standards-compliant parts work very well. But few people require the damn standard. If you want good receptacles in the US, get stuff that's marked "Federal Specification W-C-596 rated" (aka "Fed Spec"; "Spec Grade" is self-certified to... something... which is... not the same thing... but in practice the manufacturers seem not to abuse that term too much; often lower-volume part numbers seem only to be available as "Spec Grade" presumably due to testing cost). It will perform well.
