After the emergency socket is plugged into the appliance, there is electricity in both holes

It's one of the wires of your socket that is broken, the neutral wire is broken, and the live wire (the phase wire is not broken). After plugging in the electrical appliance, you take the electric pen and follow the line to find the breakpoint, and if the electric pen does not light up, it is the breakpoint position.

The common fault is that the zero line fuse of the entrance switch is broken, and the fuse of the live wire is not broken.

This is most likely because the neutral line is broken, and when the live wire passes through the load (the TV) and is transmitted back to the neutral wire, the neutral line is open.

So that there is no loop formed in the circuit, so it is measured on the socket that both wires have electricity.

There are two wires inside the socket, and one zero and one fire are connected separately to the two binding posts. It may be that the neutral wire of the binding post inside the socket is broken.

Just pull the switch open and check that it's connected.

It's a very simple thing, unplug all the electrical equipment from the socket, and then use the electrical test to see that the socket only lights up one end, which proves that there is a problem with the electrical equipment, and the same test. If it doesn't work, it's the neutral line of the socket itself or the main circuit.

Then there must be something wrong with the electrical appliances! Is your so-called normal the test all have electricity? Normally, one plug-in pen light will turn on and the other won't!

Look for the zero line in **broken, if you can use it now, there are too many electrical appliances for the power strip, the thermal protection switch jumped open, and the zero live wire of the socket is reversed.

The plug-in has two wires, one of which is broken, and it is enough to replace it with one wire.

You are the zero line of your socket is broken, just connect it from the moment.

It's good that the zero line is broken, and it's good to find it.

There is electricity in both holes of the socket, which means that there is a problem with the power wiring of this socket in your home! The most typical fault is the zero line break, or the hidden danger of poor contact caused by dripping!

Under normal circumstances, only the hole of the live wire will be electric when tested with a voltage tester! And the zero line has no electric display!

It is based on this characteristic of the line of fire and the line of zero that people can easily determine who is the line of fire and who is the line of zero!

Therefore, you only need to check very carefully whether the wiring from the power supply to the socket, including every screw, is loose? Is the gap between the copper sheets inside the socket too large? Has it caused the occurrence of poor exposure?

In particular, we should focus on checking the zero line, and we will definitely be able to find the problem!

Remember: be sure to pay attention to safety when inspecting and repairing!

Both jacks of the socket are live, that is, it belongs to the phenomenon of neutral line live. When the neutral line in the socket is live, the main switch should be pulled down immediately, that is, the gate that controls the circuit in the distribution box, and then come to check, and never use it again. One is that there is a possibility of damage to electrical appliances, and the other is that there is a possibility of electric shock.

When a problem is found, a "protective zero" is required. If the electrical equipment using protective grounding is damaged, the short-circuit current generated by the "phase" to "zero" is much larger than that of the protective grounding method, so it can promote the action of the fuse or automatic air switch in a relatively short time and quickly cut off the power supply; Since the neutral line and phase line are generally laid in parallel, it is safe and convenient to use protection to connect to zero.

The two jacks of the socket have electricity, which can be divided into two situations: 1. If the socket can be used normally, it belongs to the induction electricity generated.

2. If the socket cannot be used normally, it is a fault of the zero line disconnection; Find the broken part of the zero line and re-establish it.

There is "electricity" in both jacks of the socket, indicating that the neutral line is disconnected!

Just check the wiring, find the disconnection, reconnect it, or replace it "like a fuse"! aqui te amo。

The zero wire and live wire of the socket are electrified, and most of this situation is related to the virtual connection of the zero wire, and the zero wire can be tightened on the zero wire row.

Both jacks of the socket are electrified, the first one is to see if the two are live wires, the second live wire is broken, the zero wire is powered, and both are electrified.

Disassemble and overhaul, the inside may be connected to electricity or the neutral wire may be disconnected.

It should be a problem with the zero line, check that it may be that the zero line has a broken circuit fault.

In the case of the normal start of the socket in your home, we need to use an electric pen to detect it, only the hole on the right, in fact, is the zero line of the live wire, and the electric pen will light up. The hole on the left is the zero line, and the electric pen generally will not have light, and the ground wire will not be bright. But now such a question arises:

What is the matter with household sockets, both of which are electrified?

The socket in everyone's home, whether it is a three-hole or a five-hole socket, when they deal with the socket, the one on the left is connected to the neutral wire, and the one on the right is connected to the neutral wire of the live wire. In that case, only the neutral line of the live wire can be electrified, in fact, when the electric pen is used to test, the electric pen will be lit, and the hole of the zero line will generally not be lit.

In the case of our current measurement with an electric pen, both holes will make the electric pen bright. That means that both the neutral and neutral wires of the live wire are electrified. In household electricity, if the hole of our electric pen to measure the zero line is also electrified, it means that this and the zero line have also become the zero line of the live wire, and there is a current and voltage close to 220V to the ground.

In fact, there is only one main reason for the working voltage of the neutral line to ground, that is, the disconnection or serial power of the neutral line.

When the zero line in the circuit of the socket we detect is disconnected or connected to the phenomenon, the phenomenon of poor contact. At this time, there are other electrical products inserted in the circuit, in this case, it may cause the zero line and the zero line of the live wire to be connected, and it is very impossible to generate a circuit back to the distribution cabinet. At this time, this kind of zero wire is quite the same as this live wire, so it is charged at this time.

After the zero line in the socket is electrified, we must immediately pull off the electric switch, which is actually the gate that controls this circuit in the distribution cabinet, and then carry out safety inspections, and must not be applied again. One is that it can destroy household appliances, and the other is that there is also a possibility of electric shock accidents.

In fact, it is not very difficult to check the live method of the zero line, and after we disconnect the switch of this circuit, use a multimeter. It is to accurately measure whether the zero line in this circuit is unobstructed through the buzzer file of the multimeter. When a digital multimeter beeps, it indicates that the neutral line is on and is not disconnected; If the DMM does not reflect, it is said that the neutral line is blocked, and the neutral line at a certain point in the route is disconnected.

Then we have to test the segments in this circuit with a multimeter to find the disconnection and find the neutral disconnection position. The zero line is disconnected or connected, basically appears in the connection line of the socket or in the distribution cabinet, everyone is the first to check these, if you do not find it, and then check whether the cable is disconnected.

Now when we use an electric pen to measure, both holes will make the electric pen bright. That means that both the live wire and the neutral wire are electrified. In household electricity, if the hole of the zero line of our electric pen is also electrified, it means that this and the zero line have also become the live wire, and there is a voltage close to 220V to the ground.

So there is only one reason why the neutral line has voltage to ground, that is, the disconnection or virtual connection of the neutral line. When the neutral line in the circuit of the socket we measure is disconnected or virtually connected, and the contact is poor. At this time, there are other household appliances plugged into the circuit, in this case, it may cause the live wire to be connected to the neutral wire, and the loop back into the distribution box cannot be formed.

The reason why both holes of the socket are live is that the neutral line is broken or the moisture insulation is poor. The solution is to replace the neutral wire or tighten the loose wiring of the neutral wire of the safety seat.

The reason why both holes of the socket are live is that the neutral line is broken or the moisture insulation is poor. In the process of using household appliances, it is best to use an electric pen to measure, which is also designed to better facilitate people's lives.

The socket has power in three holes and has no power in two holes? A five-pin socket, there is electricity on the three holes and there is no power on the second hole, the socket is broken or the product is unqualified. Inside the five-pin socket, the three-hole live wire copper sheet is connected with the two-hole live wire copper sheet (the same L terminal), and the three-hole neutral wire copper sheet is connected with the two-hole copper plate (the same N terminal).

In the actual product, it is made of the same copper sheet and will not be connected by wires. The contact copper part of the five-hole socket cannot be disassembled (sealed injection molded, broken can only be replaced directly.)

In the installation of wires, we should know the principle of left zero and right fire in the middle, red is the live wire, blue is the neutral line, and the yellow and green two-color wire represents the grounding wire.

There are several scenarios for reference:

1.The switch of the socket controls the zero wire, there is no control live wire, the two feet of the socket are connected to the live wire and the neutral wire respectively, and the socket can be used normally; If the two wires of the socket are charged with a voltage tester, one is bright and the other is dark, it means that the wire insulation is poor, or the grounding of the zero line of the power supply system is not good, and it needs to be repaired urgently. The lamp controls the zero line, and the live wire is directly connected to the bulb and returns to the switch through the bulb, so the light switch has electricity, the bulb is turned off, and the lamp head has electricity, if there is electricity in one foot, there is no electricity; If the light switch is turned on, the light is on, the light switch is not powered by the voltage tester, the power supply line is normal, pay attention to safety.

If both feet have electricity, one is bright and one is dark, it proves that the power supply line is not well grounded, and find the property or power supply department to repair it as soon as possible.

2.The switch of the socket controls the live wire, there is no control of the zero wire, the two pins of the socket are connected to the live wire and the zero line respectively, and the socket can be used normally; If there is electricity on both legs of the socket, check whether the zero line contact is good, from the entrance line to the socket, if it is intact, there is a problem with the power supply line, find the property or power supply department for maintenance; If there is only electricity, it is normal. The light should be on or not, and the light switch should be electrified.

If the light switch is turned off and the two feet of the switch are electrified, it proves that the zero line is in poor contact or the line is faulty and must be repaired; If there is electricity in one foot, it is normal.

The zero line of the power supply system is not properly grounded, which has nothing to do with the user, and needs to be solved by the power supply maintenance department or the property department.

The switch of this lamp and other lamps controls the zero line, so that the two binding posts of the lamp holder are electrified, if it is a threaded lamp head, it will be electrocuted when it touches the thread when changing the bulb; For example, the socket should be measured with a multimeter, and it is 220 volts to use it with confidence. It is generally known that the electric pen is bright, but there are many cases that can make the electric pen bright, sometimes the humidity and oil smoke can make the insulating part show "electricity", and it is normal for not to be skilled in judging the electrified condition.

It may be inductive electricity, which cannot be measured with an electric pen, or it may be that the zero line contact is not good.
