China's daily voltage is 220V, 220V household electricity can electrocute people.
Industry regulations for the safety of the voltage is not higher than 36V, continuous contact with the safety of the voltage is 24V, the safety of the current is 10mA, the degree of harm to the human body of the electric shock, mainly depends on the size of the current through the human body and the length of time of energization.
The greater the intensity of the current, the greater the risk of fatality; the longer the duration, the greater the likelihood of death.
Can cause people to feel the smallest value of the current known as the perception of the current, AC 1mA, DC 5mA; people can get rid of their own current after electrocution is called the maximum current to get rid of the current, AC 10mA, DC 50mA; in a shorter period of time life-threatening current known as the fatal current, such as 100mA current through the human body for 1s, it can be enough to make a person fatal, and therefore the fatal current for the
In the case of electric shock protection devices, the human body is allowed to pass the current can generally be considered as 30mA.

Precautions against electric shock:
One of the main reasons for electric shock is that the human body may be harmed through the study of the current. causes, to improve the awareness of prevention and preventive capacity.
Second, do not privately pull, move wires, not in the transmission line, sunshine things, not in the bed head to install light bulbs, not private electricity.
Three, in the work and life as far as possible to avoid close contact with high-voltage lines. Leisure, not in the high-voltage lines near the kite, not in the high-voltage lines under the fishing pole. When a thunderstorm comes, be alert to the ground whether there is a broken high-voltage lines, once found, should be away from the broken line 8 meters away from the line in order to prevent electric shock. In addition, when encountering thunder and lightning, do not stand in open farmland, high places of buildings, next to water and under trees. When traveling in the countryside, you should also pay attention to avoid the open road, in order to prevent motor vehicles from lightning strikes.
Four, strengthen self-management. Non-work needs, should not touch the distribution transformer and other electrical equipment, and should always look at the indoor switches, lamps, wires and sockets terminals, once the junction box is found to be damaged or exposed wires, need to take immediate measures to prevent electric shock.
