They're a vast improvement over those bent bits of metal you lot use. The only criticism I've ever seen of them is that they could be considered to be over-engineered. http://en.wikipedia.org/wiki/BS_1363 Often considered the safest plug / socket system in the world btw. > We have, at most, 20 amperes at 120 volts in general use > receptacles, fed by wire that will carry that current forever > without overheating.

Why do you presume a break ? The cable used is 2.5 mm^2 btw which is 14 AWG. It's comfortably rated. Do feel free to calculate temp rise if you feel so inclined. Your understanding of UK wiring is quite flawed. Electrical problems here are exceedingly rare unknown and it's unheard of for faulty electrics to cause house fires. Graham

Complete rubbish again. Where on earth do you get this nonsense ? They used to be sold without the plug only. Nowadays a cord with plug pre-fitted or a cordset must be supplied. Graham

I know. You still need customers though. R&D isn't a freely tradeable commodity like oil or corn. Graham
