220v is still a lethal voltage, and 220V at 10A is enough to sustain a nasty arc in the right circumstances. An arc can have the temperature of four times the surface of the sun and will not neccesarily trip a noormal protective device due to its impedance. Just for interest, vaporised copper has 67,000 times the volume of solid copper, this is why it makes quite a big bang. I am an electrical engineer, most people do not fully understand the dangers of electricity and the lottery they play even at 110VAC. The "physics" of electricty are tricky at all voltages, there are recorded cases of people dying from electric shock from a 24VDC truck battery. |

yes, that's because lethality is a combination of voltage, current and the location where those are applied to the body. Apply one charge to your foot? No problem. Apply the same charge to your chest right above your heart or in some configuration where the current flows through your heart? You are probably going to have a bad day :p
