- Wrong plug or poor earthing increases the risk of accidents.
Tech Tips: Often you must have seen that homes have 2-pin or 3-pin plugs. But have you ever wondered why not all have three pin plugs and which one is considered better for home safety? Today we are going to tell you about the difference between the two plugs and how they work.
What is a 2-pin plug?
According to the information, a 2-pin plug has only two pins. Of these, one is for phase (Live) and the other for neutral. Such plugs are normally used in low power consumption devices like mobile chargers, radios, table lamps or small electronic gadgets.
If double insulation is provided in these devices then normally 2-pin plugs are considered safe. Therefore, it is not that all 2-pin plugs are dangerous.
What is special about 3-pin plug?
For your information, let us tell you that in a 3-pin plug, apart from two pins, the third pin is for Earth. Due to this third pin, the safety of the house increases more. If for some reason the wiring inside your device gets damaged and the current reaches its outer body, then the earthing pin sends that extra current directly to the ground. This greatly reduces the chances of anyone in the house getting electrocuted.
When is there greater danger?
If a person uses a 3-pin plug device with a 2-pin adapter or uses it in a socket with poor earthing, the safety system may get damaged. In such a situation, if a fault occurs, current may enter the body of the device, which increases the risk of a serious accident. Apart from this, broken plugs, loose sockets and bad wiring can also become major causes of electricity related accidents.
Which devices require a 3-pin plug?
Let us tell you that the use of 3-pin plug is very important in those devices whose body is made of metal or which consume more electricity. 3-pin plug is mostly used in devices like refrigerator, washing machine, microwave, electric iron, geyser and air conditioner. Earthing is an important part of safety in these devices and ignoring it can be risky.
which plug is better
Let us tell you that if your device is of low power and the company has designed it with a 2-pin plug, then it is considered safer to use it that way. But devices with a 3-pin plug should never be operated through a 2-pin adapter.
