Increases the current through the body; near the high pressure, there is induced currents, and therefore is very dangerous

Depending on the voltage on the human body, to determine the safe voltage 36V. When the human exposure after power, as the voltage increases, the body's resistance is lowered; if contact voltage, leaving skin breakdown due to the resistance of the body down  air circuit breaker  the body increases; close to the high pressure, as well as induction currents, so it is very dangerous. From a security standpoint, sure that the power of human  mcb circuit breaker , often without safe  Circuit breaker  with safety. Because many factors affect the current changes (such as temperature, humidity, electrical resistivity, etc.), and the power system voltage is typically relatively constant.
