I believe 48V would be used since 50V is the maximum voltage considered "safe" for humans. This is also why USB-C goes up to 48V.

It works the other way too. Low voltage is not really "safe", we can just tolerate the risk most of the time. Soak your hands in some saltwater & then grab 12 volt rails, it'll hurt like hell.

“Lick a 9V” is usually how I phrase it. Not the best feeling in the world.
