What is the difference between a three pin socket and a two prong socket?

All the pictures are three-hole sockets, three-hole sockets and two-hole sockets are missing a hole of ground wire, two-hole socket only has two holes, no ground wire, three-hole socket has three holes of zero wire, live wire and ground wire.

The difference between the three-pin socket and the two-pin socket is that there is a lack of a ground wire jack in the middle, which can protect the safety of the electricity user when the electrical equipment can be returned through the ground wire when the electricity leaks.

The power is different, the applicable object is different, the safety is different, the three-pin socket is more than the two-pin socket with a ground wire interface, and the electrical metal shell is connected, if the electrical leakage phenomenon, can protect the user from electric shock accidents.

Three-pin sockets cannot be plugged into two-pin sockets, two-pin sockets cannot be plugged into three-pin sockets, the size is not the same, the specifications are not the same, and the current is not the same.

The circuit connections inside are different, and there will be different knowledge at the same time, and the power used is also different, the purchase method is different, and the precautions are also very different.

Regardless of whether the three-hole or two-hole installation method is basically the same, it is facing the socket, the left zero line and the right live wire, and the top hole of the three holes is the grounding wire, which is to prevent the danger of electrical leakage and connect with the earth. Hope it helps.

The standard connection of the socket is to connect the live wire to L, the ground wire to E, and the neutral wire to N. However, since the home socket may contain other wires, such as the wires of other sockets, it is important to understand the function and purpose of each wire when wiring.

Hope mine is helpful to you.

The usage of the two sockets is actually the same, the other hole in the three-hole socket in addition to the L and N holes is the protective grounding hole, which can protect people when the electrical leakage, and in some old houses, there is no such protective grounding wire at all, as long as the live wire and the neutral line of the power supply are connected to the L and N holes when used, it can be used normally.

The usage and difference between the three-pin socket and the two-pin socket The three-pin socket has an additional ground wire, which is to prevent electric shock damage to the human body caused by leakage in the electrical shell. The two-pin socket only has the live wire and the neutral wire. You're right, and you're right.

The three-hole one has an extra ground wire.

The main difference is that a three-pin socket has an additional bottom line than a two-pin socket.

With the improvement of living standards, there are more and more electrical appliances in the home, and of course there must be more and more sockets in the home. Today's sockets generally have a difference between a two-prong socket and a three-prong socket. Whether it is a two-pin socket or a three-pin socket, it is very safe to use.

However, if you are willing to make your electricity consumption safer, it is recommended that you choose a three-pin socket.

Originally, appliances only had to have two cables to receive an outlet to operate. One line flows in and one line discharges. In the three-pin socket of the home circuit, the transmission wire connected to the largest hole of the pinzig type is called the grounding wire.

The other end of this line receives the underground or receives a metal water pipe, so it is also called a laundere. The launder hole of the socket touches the three-pin power plug, the thickest and thickest cutting, and then the cuttings receive the plastic shell of the electrical appliance.

For example, automatic washing machines, household refrigerators, irons, etc. need to be connected to the grounding wire. The ground wire has no current under normal conditions. But as soon as the appliance is energized, the current is entered from the chassis through the ground wire.

Because the resistor of the ground wire is much smaller than the resistor of the body, the vast majority of the current enters the ground along this line, and the current passing through the body is small enough to be safe.

Common problems with electrical socket wiring, electrical appliances are not grounded, and under normal conditions, the body is not easy to be electrocuted. Electrical appliances are not grounded, and once the electrical appliances are electrified, there will be a risk of electric shock. When the electrical appliance is connected to the ground wire, the exposed current will follow the ground wire, and the body can avoid electric shock.

According to the introduction of this article, you can understand that the two-pin socket is a neutral wire, the other is the neutral wire, and the three-pin socket has an additional ground wire. The ground wire of the three-prong socket can protect the body from electric shock, and it is more reliable for electricity consumption. If you want to buy a socket, it is best to choose a three-prong socket.

It will produce different amounts of electricity, have different powers, and have different wiring routines, which will produce different effects, different safety performance, and different electrical equipment used.

The jacks are different, the connection methods are different, the suitable products are different, the risks are different, and the installation situation is different.

The difference is relatively large, the line is not the same, the suitable items are not the same, the way of connection is different, one has a ground wire, and the other has no ground wire.
