There is a "life-saving line" in the three-wire plug

Do you often complain that the three-wire power cord plug occupies the space? It is not as easy to use as the two-wire plug power supply. I can’t wait to change the three-wire power cord into a two-wire plug power supply. In fact, one of the three-wire power cord plugs is a grounding wire. The grounding wire is not a redundant design. It is a "life-saving line". It is usually connected to the housing of electrical equipment. Once there is a leakage, most of the current flows to the earth from there. In the event of an electric shock, only a small current flows into the human body. Changing the plug of the three-wire power cord to two-wire without authorization is a joke on safety.
