other bits
yea not forgetting the Frence CC 40100 loco with 4 voltage choices!
Forget to mention the current bits
50mA (.05) can kill an adult!! especially if current flow is through the heart.
Myth - the electricity threw me
Sorry your own automatic reflexes couples with your muscle contaction does the throwing usually around 30mA. Lots of reports in my industry of severe injuries to the guy stood behind as someones arm retracts from the shock!
Cattle fences are usually around 50v as a voltage that low can produce enough current to kill a cow. warning they are very painful if you step across one and end up with one leg either side & contact is made - think about it!
