Is it safe to have only two wires for a three pin socket?

The three-hole socket can also be used with only two wires, but there will be problems with the safety of electricity without a grounding wire, and the use of some low-power electrical appliances is not a big problem, but the relative safety is not very good.

Hello! If the three-phase socket is only connected to two wires, that is, the neutral wire and the live wire, it can also be used, but the safety performance is greatly reduced if it is not grounded.

There is nothing wrong with this ordinary daily use. That is to say, in fact, you can't use high-power appliances, such as more than 3kw, basically you have to use less or no one.

Weakly asked, why do I have only two wires in the three-hole socket of my house There are only two wires in the three-hole socket of the power supply, indicating that the developer has cut corners and does not have a protective ground wire connected to the power supply, but it is still possible to use general electrical appliances, but the iron shell electrical appliances require that there must be a protective ground wire.

From the point of view of electrical safety, this practice is extremely dangerous and can cause a fire at any time.

The socket strip is a type of socket, which is just a multi-hole socket formed by putting multiple sockets together. This combination has many benefits, it can be used for multiple purposes, saving both space and lines. It is a very simple and practical invention.

Usually the socket strip is mostly a multi-hole socket with a power cord and plug that can be moved, while the socket usually refers to a fixed and mostly five-hole socket.

Socket strips, also known as strip strips, commonly known as drag strips, are necessities of life.

Qualified switch products must obtain national certification and meet international industry standards. Domestic products must pass 3C certification, ISO9000 series certification, and some international brands have also obtained other national and international safety certifications, which will be marked in the product itself, packaging or instructions through identification.

It is unsafe for the three sockets to be connected, because the sockets and sockets between each socket strips are movable, which is prone to short circuits, and sparks are easy to occur when short circuits, which is easy to cause fire disasters

It is unsafe, which will increase the power of electrical appliances and easily cause short circuits, spontaneous combustion and other phenomena.

This is not safe, if the electrical power on the socket is too large, the wire will not be able to bear, there will be potential safety hazards.

Insecurity! Now the national standard stipulates that a single socket row cannot be set up with multiple jacks. This is for security reasons.

As long as the wire is not connected incorrectly, there is no problem with the power of the connected wire, and of course it is safe.

Hello, as long as the power of the electrical appliances used is within the rated maximum power of the socket row, there is no problem in theory, but plugging in more socket strips will increase the potential safety hazards, it is recommended to replace the longer wires and connect them to the socket strip for use.

Of course, there are potential safety hazards, and the quality of the socket will affect the poor quality.

The more sockets in series, the higher the risk.

Current risk, the current of the first socket bar may be too large, causing overheating, fire hazard and electric shock hazard (if the enclosure is not well protected).

The more sockets, the less secure they are. A multi-socket strip can be installed.

Summary. The three-hole socket can be plugged into a two-hole plug, the two-hole plug is generally not a hidden danger to static electricity, and it can be used with confidence. However, it is better not to plug in a two-pin socket than a three-pin plug; Electrical appliances are three-pin plugs, and the static electricity generated by the electrical appliances reaches a certain amount, which will cause electric shock to the human body.

To what switch is installed on the zero line, left zero right fire, red fire blue zero.

and other basic common sense.

Is it risky to connect a three-prong socket to a two-prong socket?

Hello, glad to answer for you. Kiss. There's nothing risky. Is it risky to connect a three-prong socket to a two-prong socket?

Is it risky to connect a three-prong socket to a two-prong socket?

The three-hole socket can be plugged into a two-hole plug, the two-hole plug is generally not a hidden danger to static electricity, and it can be used with confidence. But the two-hole socket is best to Zen pat guess not to plug in the Sanhe carry plug; Electrical appliances are electrical appliances with Sanga type pin plugs, and the static electricity generated by the electrical appliances reaches a certain amount, which will cause electric shock to the human body. It is very useful to understand what switch is installed on the zero line, left zero right fire, red fire blue zero and other basic common sense.

I hope my reply is helpful to you.

Electricity is OK, but the lack of ground wire lacks safety protection. The three-pin plugs are the live wire L, the neutral wire N, and the ground wire. 220V AC power supply is the live wire electrical appliances The zero line constitutes a loop, the ground wire does not participate in the power supply, and only the live wire and the neutral line can be supplied in the three-pin plug.

However, the electrical appliances that use 3-pin plugs are generally metal shells or contain metal fittings, and the internal ground wire is connected to the shell, and the leakage current is discharged through the ground wire connected to the socket ground wire when leakage occurs. Therefore, it is best to connect the ground wire to the electrical appliances with three-hole plugs, which is an additional safety measure.

Hello, the three wires are three-phase wires, which are safer for high-power electrical appliances.

If you encounter similar problems in the future, you can follow the following ideas to solve them:

1. Finding problems: often living in the world, always in these kinds of contradictions, when some contradictions are projected into consciousness, the individual only finds that he is a problem, and asks to find a way to solve it. This is the stage where the problem is discovered.

From the perspective of the stage of problem solving, this is the first stage and the premise of solving the problem.

2. Analyze the problem: In order to solve the problems found, it is necessary to clarify the nature of the problems, that is, to figure out what contradictions there are, which contradictions, and what is the relationship between them, so as to clarify what results the problems to be solved, the conditions that must be met, the relationships between them and what conditions have been met, so as to find out the important contradictions and key contradictions.

3. Put forward hypotheses: on the basis of analyzing the problem, put forward hypotheses to solve the problem, that is, the solution that can be adopted, including what principles and specific ways and methods to take, but all of these are often not simple and ready-made, and there are various possibilities. However, putting forward hypotheses is the key stage of problem solving, and correct assumptions lead to the smooth solution of the problem, while incorrect and inappropriate assumptions lead to detours or lead the solution of the problem astray.

4. Verify the hypothesis: The hypothesis only proposes n possible solutions, and there is no guarantee that the problem will be solved, so the last step in problem solving is to test the hypothesis. In either case, if the test does not produce the expected result, a new hypothesis must be proposed and tested again until the correct result is obtained, and the problem is not solved.

The brown line is the fire wire, the blue line is the zero line, and the yellow and green color line is the ground wire. Just connect the brown and blue lines. But it's best to connect the three-pin plug so that it's safe.

The two wires are connected to the two pin terminals under the three-pin plug, the lower left corner is connected to the neutral wire, the lower right corner is connected to the live wire, and the upper one is the grounding wire that does not need to be piped. Then reinstall the triple plug and it's connected.

The three-wire plug is a live wire, a neutral wire and a grounding wire, and the function of the three-wire plug is to better protect the safety of the staff using household appliances with metal shells, so as to prevent the staff from leaking electricity and electrocuting during use.

Three-wire plug structure:

Three-pin socket: "left zero right fire on the ground" (the ground wire is generally connected to a metal plate buried in the ground). Three-wire plug:

Appliances with metal casings are basically three-wire plugs, which correspond to three-pin sockets. The function of grounding: the plug in the middle of the three-wire plug is connected to the metal shell of the electrical appliance, and when the three-hole socket is inserted, the metal shell is connected to the earth.

Civil 220V electricity, one live wire, one neutral wire, three wires for safety, plus a ground wire, it is safer to have a grounding wire.

The first method of connection. The live wire is connected to the leftmost hole, the zero wire is connected to the adjacent hole, if there is a ground wire connected to the hole in the middle, if you want to control the lamp, then the switch control wire is connected to the hole on the top of the switch, this is a socket with a switch, the second connection, if you want to use the switch to control the socket, then the live wire is connected to the hole above the switch, and the zero wire is connected to the hole on the right.

The 220V voltage itself is two wires, a live wire and a neutral wire, and the third wire is a grounding protection wire, there is no electrical appliances can operate normally, why add an additional grounding protection wire, is it an extra move, the answer is no, the general small household appliances are plastic shells, even leakage will not hurt people, so the use of two wires can be, and some household appliances shells are iron, due to some reasons the live wire on the terminal is loose and falls off, the shell of the electrical appliances will be electrified, Once a person touches it, it will be electrocuted, resulting in **, with this grounding protection wire, it can lead the current into the ground, so as to play a role in the safety protection of people!

1. How to connect the three wires in the socket.

The socket is usually connected to the neutral wire on the left, while the live wire is connected to the right side, and the ground wire is in the middle. The line in the normal socket, the red wire is the live wire, the blue wire is the neutral wire, and the yellow and green wire is the ground wire, and we can connect it according to the color. So the red wire is connected to the live wire, while the blue wire is connected to the neutral wire and the green wire is connected to the ground wire.

When wiring, they cannot be connected incorrectly, otherwise there will be certain safety accidents.

When wiring in the home, whether it is a metal crust or a metal wire, it must be grounded and protected. And the laid lines must be kept in meters. When laying wires, the wires should not be directly embedded in the cement.

Generally, the depth of wire embedding must be more than 10 mm. If there is a cast-in-place concrete floor, be sure to use a sheathed line.
