[...] Our power sockets are only 3kW each - but it isn't the Watts that really hurt, or even the Volts; it's the Amps you really need to be careful with. 60 Amps at a Japanese 100V would be a lot more dangerous than 30 Amps at a European 230V. (Although either could kill you, so the difference could be academic as far as the one grasping the wires is concerned). Notice that fuses and cut-outs are rated in Amps, and that "non-lethal" stunners for the cops are rated at tens of thousands of volts. In the right (or wrong!) circumstances, the current that will make a torch bulb glow can be enough to stop the human heart. -- -- ^^^^^^^^^^ -- Whiskers -- ~~~~~~~~~~
