Never could figure out the actual reasoning behind it but I do know I

Maybe the thought is at 230v, the arc takes longer to extinguish when
you pull put a plug under load and the switch is designed to do it
better.

It depends on the type of electricity.

Nuclear power has a small amount of residual radiation that can leak from devices. While coal seems safe, power generated from coal often releases small amounts of carbon monoxide into the home. Probably the safest is hydro power but water can condense
out and corrode the connections. Since the oceans are becoming more acidic, I'd expect to see inter-granular corrosion appearing in aluminum mains wiring too.

Well Al, what about solar power? Can one use the wiring for a flashlight?
What about wind power? Do it suck or blow at the end of the wire? I thought
those plastic stoppers were to keep them from leaking.
