Just a note,
Our socket-outlets over here, have had safety shutters in them for some time.(since the late 1980's, by memory)
You have to be able to have a pin fully inserted into the neutral aperture before the phase aperture will open enough to get the pin in.
Sure, it may be a nuisance to those that regularly require to get test equipment probes into sockets, but hey, if it saves some kids life, it's no more than a small inconvenience.
