Wet weather is easy to get an electric shock, because

I=U\R It can be seen that the current passing through the human body depends on the human body resistance, which is mainly in the cortex. If the human body is wet, it is equivalent to lowering the resistance and the current flows through the epidermis. There is a very extreme example: when a person just gets an electric shock, the current flows through 30mA, but after a certain period of time, the human skin is punctured, so the current flows directly through the blood, and the current can rise to several hundred amperes, so it is impossible for a person to survive.

Wet and rainy weather reduces the insulation performance of electrical equipment. At this time, the power consumption of electric fans, air conditioners or temporary lines increases, and the relevant operators may not wear work clothes or insulating protective gear because of the hot weather. In addition, at this time, the human body sweats and is easy to conduct electricity.

There are several main reasons for electric shock: 1, because there is no leakage protector at home.

2, leakage protector failure, can't guarantee more than 30mA leakage and trip.

3. Because the ground wire at home is not well grounded.

4. The metal shell on the electric water heater used is not grounded or poorly grounded.

5. The local water quality is not good, and there are many minerals containing calcium and magnesium in the water, which makes the shell of the electric heating tube have scale. Some families don't turn off the electricity and clean the water tank for a long time, which leads to the heat in the electric heating pipe can't spread quickly, and the temperature rise is easy to corrode the shell of the hot rod, which leads to the current entering the water. When someone takes a bath, electricity will knock him down immediately.
