Electric water heater problem (ground. Anti electric wall = =`` etc.)
A wire, you take a bath is standing on the ground, leakage this time, because the resistance of your body than the ground resistance, so the current through the resistor smaller local transmission to the ground, not through your body or a small part through your body, you will feel tingling. Without wires, the landlord thinks, 220V voltage flows through your body to the ground, your body is a wire, you can withstand it?
If there is no ground wire, when you take a shower, the water heater is out of circulation. You are standing on the ground, and the current will pass through your body to the earth, so you will get an electric shock. It's life threatening for you!
The line is designed to prevent leakage of electricity and cause damage to the human body. The ground wire is connected to the outer shell of the electric appliance (the heater is attached to the outer shell of the heating body or at the water outlet), and one end is connected to the ground. Usually more than 4 copper core wires are connected. Suppose you are in the bath when the water heater leakage, then you can transfer the current to the ground through the earth wire, at this time leakage protector detects leakage, leakage protector cut off the power supply. The water heater stops supplying electricity and the electric current stops. It's safe for you.
