3 phase 440v but low amp wont do much damage to human. Will feel the zap lah.If i recall correctly, its not about the voltage ( V ), its the current ( A ) that hurts us.
For example, car battery is only 12V but there are variation of capacity. I did mention that i dropped a wrench and it made + to - connection on the Pajero battery....that split second contact left a permanent mark on the terminal and manage to warm up the wrench. Imagin the energy that is stored in the battery.
Another proof is that i have seen video where offroader hook up 2 unit of 12V battery and uses it to weld.
Engineering manager told us very lucky becos few of us kena zap by voltage leak into electrical panel.
