What happens when there is no electricity in some of the sockets in my home?

The reason why the lights are on at home, but the socket is out of power:

The lights are not powered by the socket on the same branch, they are controlled by two air switches. So, when the switch of the control socket trips, although the socket is out of power, the light is still on.

The electrode in the socket is detached from the connection wire, causing the wire to have electricity, but there is no power on the electrode, and the appliance cannot work when plugged in. Produces the phenomenon of lights on but no power at the outlet.

The power supply wire of the socket is in the wall, and the wire is broken due to the qualitative change of the house, such as the cracking of the wall, etc., which eventually leads to the lack of power in the socket.

Solutions to the above problems:

If the lamp and the socket are controlled by two air switches, and the switch of the socket trips, it is possible that there is a serious short circuit in the electrical appliances inserted into the socket, at this time, the short-circuited electrical appliances can be unplugged from the socket and the socket can be supplied with power separately to restore the socket to normal operation. And if the appliance is damaged, you can ask a professional to repair it. When the electrical appliances plugged into the socket exceed the capacity of the switch, it should be unplugged in time, used according to the requirements of power use, and replaced with a large-capacity power supply socket.

The electrodes in the socket are detached from the connection wire, which is usually caused by the loosening of the fastening screws of the wire joint, and this situation is very dangerous. Because when loosening, a large resistance is generated locally, so that the sudden heat increase of the current will exceed the original temperature by hundreds of times, and fire accidents are easy to occur. Therefore, when installing the socket, be sure to tighten the screws of the terminal to ensure that the connection between the wire and the electrode is tight.

The phenomenon of wire breakage caused by the qualitative change of the house needs to be reported to the property, and the property electrician will carry out timely emergency repair to avoid electric shock accidents due to exposed wires.

Precautions: water, fire, electricity ruthless and fierce as a tiger, when encountering problems with the circuit at home, it is recommended that users without electrician foundation do not repair privately to avoid electric shock accidents. If a fire occurs caused by a power line, do not use water to extinguish the fire, but cut off the power supply (pull the brake) as soon as possible before extinguishing the fire and call for help in time**.

Sockets, also known as power sockets, switch sockets. A socket is a socket through which one or more circuits can be plugged in, through which various wiring can be inserted.

This makes it easy to connect with other circuits. Through the connection and disconnection between the line and the copper part, the connection and disconnection of the circuit of the circuit can be finally achieved.

The contacts inside the socket are copper sheets, and the copper sheets are connected in one row or even more rows.

1. It is because of the deformation of the copper sheet in the plug board, which makes it impossible to make close contact with the plug.

2. Frequent plugging and unplugging, and inconsistent plug specifications, resulting in copper breakage.

3. On the jack without electricity, whether the copper sheet is consistent with other jacks with electricity (discharge deformation).

4. Disassemble the plug board to check whether there is any fracture or loose joint.

In order to further standardize indoor wiring, reduce potential safety hazards and waste of repeated disassembly and assembly, and work with enterprises to create a consumer environment with good consumer peace of mind and good market order, the National Electrical and Intelligent Cooperation Alliance invited electrical experts to jointly launch a series of suggestions on "electrical appliances are delivered safely to the home", giving consumers detailed and effective knowledge from various aspects such as material selection, wiring, switch and socket design, and network TV line design. And guide consumers to choose the right home improvement company for themselves and how to communicate with designers in the home improvement process.

According to what you said, the main line (thick wire) that supplies power to the socket is in poor contact or loose, or the empty opening of a pipe socket jumps, or the socket wire in the junction box in the indoor line is loose.

Find the incoming switch box of this house, there should be a row of empty inside, about three or four. Some are tube lighting, some are tube sockets, and it is good to push them up directly if they jump. If you don't jump, use an insulated wire cutter to tighten all the open incoming and outgoing wire ends.

Pay attention to safety and do not get electrocuted (wear insulated gloves and stand on the wooden board, etc.). In that case, the problem should be solved.

If this doesn't work, it should be loose on the wire box, this is not something you can get, you go to the maintenance master.

It is determined by the inlet cast of the power cord and the air switch connection of the control socket circuit. If the inlet head is not in good contact, or if it falls off, or even if the wire is oxidized, the socket will run out of power.

2. The air switch trips. If there is a problem with one of the circuits in the home, causing the air switch to trip, the sockets and switches in the home will not have electricity. Usually, the causes that cause the air switch to trip are circuit short circuit, circuit overload, leakage, etc.

3. The wire inside the socket is broken. Inside the socket there is a neutral wire and a live wire, if one or both of these two wires are installed.

Some of the sockets in the home are out of power, and some of the power is caused by the line breaking or the branch switch tripping.

1. Check whether the branch switch is tripped or damaged.

2. Check whether the branch power supply line is open.

Here's how to fix it:

The first method: break the switch of the socket in the kitchen and bathroom, and then close it.

The second method: check the distribution box at home, and use a test pen or multimeter to check it out.

The third method: check the corresponding air opening, whether there is electricity in or out, whether there is electricity in and out, if there is no in and out, that is, the air opening is broken. If there is electricity at one end of the empty opening, that is, the line is broken, and you can use an electric pen to find the corresponding empty opening.

1. There may be a power outage, this situation is also more common, we can directly call the power supply company, report the fault, request maintenance, it will not take long, maybe you will be able to call.

2. It is also possible that the leakage protector at home has tripped, and once tripped, all the sockets in the home will be out of power.

3. It is also possible that the socket at home is damaged, and once the socket is broken, it will also lead to the problem that it will not be powered on.

Summary. Some sockets have electricity, and some sockets have no power1, because of the deformation of the copper sheet in the plug board, resulting in close contact with the plug. 2. Frequent plugging and unplugging, and inconsistent plug specifications, resulting in copper breakage.

3. On the jack without electricity, whether the copper sheet is consistent with other jacks with electricity (discharge deformation). 4. Disassemble the plug board to check whether there is any fracture or loose joint. It is also possible that the wiring is not the same wire in the first place.

There is no electricity in the living room and bedroom sockets, and there is electricity in the kitchen, bathroom, and dining room.

Some sockets have electricity, and some sockets have no power1, because of the deformation of the copper sheet in the plug board, resulting in close contact with the plug. 2. Frequent plugging and unplugging, and inconsistent plug specifications, resulting in copper breakage. 3. On the jack without electricity, whether the copper sheet is consistent with other rock-sensitive jacks with electricity (discharge deformation).

4. Disassemble the plug board to check whether there is a break or a loose joint. It is also possible that the thick wiring is not the same wire.

It could be a trip or a line fault. 1. Check the power distribution box at home, confirm whether there is a multi-stage air switch with room or function, and check whether it is a buried ruler brake if there is. After closing, see if there is electricity in the study bedroom.

2. If the power distribution box does not have a multi-stage air switch with room or function, the line is faulty. a. Check whether there is any false reputation connection or ablation in the power box; b. Check whether there is a junction box on the line of the buried piping, and open it to check whether there is no false connection or ablation bending height; Corresponding processing is carried out.

The reason why the lights are on, but the sockets have no power, is mainly because the sockets and lights at home are not in the same circuit, so they will not be affected. If there is a problem with the switch that controls the socket at home, such as a tripping situation, it will cause the socket to have no power, but the light is on.

1. When encountering this kind of problem, first of all, we should check whether the wires connected from the switch of the control socket circuit to each socket are not in good contact, falling off and oxidation, and whether the connecting screws of the thread head are tightened. If this happens, just tighten the places where the contact is not good and the screws are loose.

2. If there is no problem with the socket itself, we can also check whether the switch has tripped. As long as the plug is unplugged first, and then try to close the switch, if it still jumps, it means that the line has a short circuit; If it doesn't jump, it means that the line may be overloaded, or some household appliances are leaking.

Precautions for wiring household switch sockets:

1. Pay attention to distinguishing wires.

As we all know, there are three kinds of wires, namely live wire, neutral wire and ground wire, if it is connected wrongly, it is easy to have electrical safety problems, especially when the socket is wired, these three wires have a specific connection point, generally the L port is connected to the live wire, that is, the red or brown wire, the N port is connected to the neutral wire, which is the yellow wire, and the E port is connected to the wire, which is a two-color wire.

2. Pay attention to the installation height.

When installing the switch socket on the wall, we should pay attention to the installation height, the height of the general switch is relatively unified, and the height of the socket is inconsistent, and it should be installed according to the use of electrical products, for example, the height of the air conditioning socket can not be too low, its height can not be lower than the meter, the bathroom concealed socket can not be less than the meter, and the kitchen and bathroom socket can not be lower than the meter.
