Why Ground Wire Is Important

Electricity is one of the greatest inventions of humankind, and now we need electricity in every aspect of our lives. But at the same time, electricity is invisible and untouchable. In electric shock, the current is small and lucky, but if the current is too large, it will endanger human life to ensure personal safety. People added the third wire for the electrical appliances -grounding cable.

In this way, when the appliance’s insulation is damaged. The electricity flows from the ground into the ground, and people do not have to worry about being electrocuted. But someone may say: “I have seen a lot of appliances, but never see what line into the ground ah?” Ground wire, not from each appliance to connect a wire, and then buried in the ground.

Most of the devices are wired earth. General electrical appliances are equipped with grounding devices on the shell. When using the instrument, the plug is grounded. You seem to appliances do not seem to be grounded. The colour of the ground wire is generally yellow-green. In the cable industry, we also named earth wire.
