Grounded plugs and ordinary plugs are two different plug types, and they have obvious differences in structure and use.
1. Structural differences
Grounded plugs are constructed differently than regular plugs. A grounding plug has three pins, namely live, neutral and ground, while a regular plug has only two pins, namely live and neutral. The third pin of the grounding plug is used to connect the metal shell of the electrical equipment so that the electrostatic charge in the electrical equipment can be directed to the ground to ensure personal safety.
2. Differences in use
There are also differences in the use of grounded plugs and regular plugs. Grounding plugs are generally used for electrical equipment that require grounding protection, such as refrigerators, washing machines, ovens, etc. These electrical equipment will generate electrostatic charges during use. If there is no grounding protection, these charges may cause harm to the human body. Ordinary plugs are suitable for electrical equipment that does not require grounding protection, such as TVs, computers, mobile phone chargers, etc.
3. Security Differences
Ground plugs are safer because they have an extra ground pin. When electrical equipment fails, the grounding plug can conduct current into the ground to avoid electric shock accidents. Ordinary plugs do not have this protection function. If the electrical equipment fails, it may cause an electric shock accident.
4. Differences in scope of application
The scope of application of grounding plugs and ordinary plugs is also different. Grounding plugs are generally used for electrical equipment that require grounding protection, such as high-power electrical appliances, industrial equipment, etc. Ordinary plugs are suitable for some small electrical equipment, such as mobile phone chargers, desk lamps, etc.
To sum up, there are obvious differences between grounding plugs and ordinary plugs in terms of structure, use, safety and scope of application. When using, the appropriate plug type should be selected according to the needs of the electrical equipment to ensure personal safety and use results.
