If a person stands on a plastic stool and touches the electric wire, can he not get an electric shock? What is the live work?
Live working is in no condition to cut off the power switch or socket, is to stand on the insulator body alone touch a wire, that is to say, a joint, metal head as long as they do not reach the two line on the line, if it is connected to the main case the wire ends, respectively through the rubber, with a rubber handle pliers to twist up two lines, wrapped with insulation tape on the line.
As long as a man is standing on the insulating body (but not wet), hand to touch a single FireWire will not remember a single shock, because of this, the current through the wire to the ground between the body and the insulation does not form a loop shaped partition, will not happen.
