What Is A Ground Wire?

The ground wire directly connects to the earth, which can also be called a safety wire. It is dangerous when the high voltage directly transferred to the earth, considered a life wire. Household electrical equipment due to poor insulation or a wet environment will lead to its shell with inevitable electrostatic, serious electrocution accidents. To avoid accidents can be connected to a wire above the appliance’s metal shell, the other end of the wire into the earth, once the appliance leakage when the earth wire will be brought to the planet to release static electricity.
