The first category: appliances with double insulation measures to increase leakage protection, can not ground protection (that is, you can plug two feet). Such as: TV, electric fan, table lamp, etc.
The second category: Electrical appliances refer to electrical appliances with only one layer of insulation. These appliances must be equipped with leakage protectors and grounding protection (that is, three-pin plugs). Therefore, one foot above the three-pin plug is used for grounding protection.
