A pregnant woman in a rented house in Shenzhen got an electric shock while taking a shower. Her husband was killed in her rescue. How could she get an electric shock in the shower?

Water is not an insulator, but a semiconductor. It is easy to get an electric shock when people have water in the bath. When getting an electric shock, the live wire forms a loop on the ground, and the current passes through the human body, causing an electric shock. There are several reasons. Unreasonable installation of electrical equipment, no equipment grounding wire.

Electrical equipment, leakage, resulting in water charged.

Incorrect use, resulting in accidents. To prevent electric shock, you should do the following:

First, don't touch or touch electrical equipment, especially when your hands and feet are wet, don't operate live electrical appliances, such as pressing the switch with wet hands and plugging and unplugging the power cord.

Second, when electrical equipment breaks down, don't disassemble it yourself, especially if it can't be operated live. You should have it repaired by a professional.

Three, electrical accidents, be sure to connect the zero line and grounding protection device. And check regularly to ensure safety and reliability. Do not use inferior, worn and damaged wires or electrical equipment.

4. The buttons, switches, sockets and wires of the distribution box that are frequently contacted should be kept intact, and the aging and damaged parts and wires should be replaced in time.

5. Configure elevator equipment and wires according to the safe load of the project, and do not arbitrarily increase the load to prevent short circuit and leakage caused by overheating of wires.

Six, the back of each socket is marked with the tolerance range of electricity, such as 220 volts to 250 volts. When using the socket type, make sure not to exceed the maximum current carrying range of the socket.

7. Don't use a socket for electrical equipment with high power consumption. Electrical appliances with power exceeding 800 watts should be provided with separate sockets, which cannot be shared with other electrical equipment.

Eight, long-term unused electrical appliances should be unplugged, winter air conditioners, set-top boxes, televisions, and long-term unused mobile phone charging appliances. Be sure to unplug it to ensure safety and save electricity.

Home distribution meters, such as digital meters. Ordinary electric pens may not detect leakage. Digital pen has high sensitivity and can measure very low voltage.

You can install a leakage circuit breaker at home, connect the water heater and turn on the switch of the water heater. If the water heater does not trip, it means that the leakage current is safe below 30 mA.
