Armored power plug ET-1313-16A Ettehad Electric

If you have just bought a laptop or mobile phone, you will notice a charger or power cord that consists of three plugs instead of two. To be able to use it, you have to take a head and tie it to its head to turn it into a fork. Now we will explain the reason for this and what is the difference between the two.

Reasons to use three and two branches:

Electrical appliances need two pins to work. The third wire is not needed to operate electrical appliances. Even if you cut this wire, the appliances will still work. So what is the function of this third wire? What is its duty and role? The role of the third wire in the three branches is to protect you against electric shock. If for any reason an electric current is connected to the body of the device and you accidentally touch it, you may be electrocuted and irreparable damage will be done to you.

Three branches and the reason for using the third wire:

For this reason, a third wire is inserted so that the extra current is directed to the ground instead of being directed to your body if it is connected. In Iran, however, three branches are used instead of two, because this issue has not been taken very seriously. Instead, electrical protection is used to prevent hazards.

How do the three branches work?

If you look closely at the three wires of these three branches, you will see that the brown wire is the color of the phase wire. The blue or black wire is the same as the neutral wire. The green or yellow wire is also the ground wire. The phase wire is connected to the fuse. The fuse base is connected to a three-prong pin. If the current increases for any reason, the fuse blows and the power goes out completely. The basis of the fuse is that when too much current passes through it, the wire inside it melts due to the high current and the electrical circuit is cut off, and this causes the power supply to be cut off. For this reason, it can be a protector of human life and has more of a safety aspect.

How to turn three branches into two branches?

In Iran, due to the fact that the power switches are dual, the three branches can not be used. In order to be able to use it and turn it into a fork, you can use a scythe. It has a low price and can be easily found in electrical stores.
