I'm not able to find the link right now, but Technology Connections did a fantastic breakdown of the designs for U.S. plugs/outlets compared to those in (I think) the U.K.
Unsurprisingly, our outlets in the U.S. feature several braindead design choices that make them more dangerous.
The sockets were adequately designed for the plugs of the time. Then we started cramming transformers, capacitors and regulators into them to convert ~high voltage AC to low voltage DC.
The plugs changed, but the sockets took forever to barely catch up, if you can even say that much.
The more concerning thing is how they leave exposed live metal that you could touch while inserting/removing if you're not careful.
I really like where some countries have the prongs partly insulated so you can’t electrocute yourself as easily. It seems like it could be cheaply and easily done in the US as well, if we cared to do so
At this point you can get gfi plugs, abd chil proof plugs that block the live outlet. At this point all wr can add is plastic wrap at the base of the prongs
