I don't agree with this at all. We have safety sockets in the US, fuses in every plug is just one more thing to go wrong, and what they call circuit design is really just industrial design and I'm dubious that it would do anything.

This is the weirdest UK flex.

English plugs are designed to land pins up and stab unsuspecting intruders in the foot. That's the best design feature because A: defence, and B: accidentally pulling the plug out is harder as the cable exit is mostly never in the pin direction.

* Pin contact order is guaranteed.

* Shuttering of L/N is mandatory.

* Also not a plug thing, but 230V = lower current = lower heat, less fire risk. And less copper!

This makes it seem like the brits have trouble plugging things in, that can't be right. I've never had a power cord get "hot" either.
