Why does the main gate of the whole building jump when there is a short circuit in the house?

Common causes and how to fix them:

What needs to be done is to test the insulation resistance of our indoor lighting circuits.

Circumstance. The main purpose of detecting the condition of the lighting circuit is to determine whether there is leakage in our circuit. As we all know, the insulation resistance value of household wires is not allowed to be less, we can use the shake meter.

to measure the insulation resistance value of the wire.

We need to check our indoor circuit for short circuits. In order to check that there is a short circuit in the energy wire, a multimeter is basically used.

to check. The use of the multimeter is to use the multimeter's buzzer file, we put the two hands of the multimeter on the live line and the zero line of the lighting circuit respectively, if you find that the indicator light of the multimeter flashes or beeps, it is basically a short circuit.

Replace with a new air switch.

The type and quality of air switches at this stage are uneven. Therefore, I personally recommend that you buy a better air switch, replace it, and then see if there are any similar problems.

The relationship between the gate and the indoor lighting gate.

The first point is that we need to know the specific role of the main gate of the corridor. Like the current commercial housing, there is a main gate in the corridor on each floor, and the location of this main gate is generally in the pipe well with strong electricity. In addition, the main switch is basically a circuit breaker, rather than an ordinary air switch, which has the protection effect of short circuit, overload and leakage.

The second point is that we know that the lighting circuit in the home is usually an ordinary air switch. The function of the air switch in the lighting circuit is to prevent overload and short circuit in the room, but it cannot prevent leakage.

The third point is that we need to understand the relationship between the outdoor main gate and the indoor switch. The outdoor main gate is generally the control of the electricity consumption of all households on the first floor; The opening of the indoor lighting circuit is to control the electricity consumption of our indoor lighting circuit.

In my opinion, if the home is short-circuited, the whole building will jump the whole building, it means that the line at home and the line of the whole building should be under the same controller switch, so that the home and the whole building will trip, and the normal circuit installation will only be a short circuit at home, but the whole building will still operate normally, and this situation will not occur, because generally speaking, if it is a split switch, this kind of thing cannot occur, only the overall switch, that is, the whole switch, this problem may occur.

There are several possible scenarios for this:

1. Only the main gate of the whole building is equipped with leakage insurance.

2. The leakage insurance of your home is greater than the leakage insurance of the main gate of the whole building.

3. Your home leakage warranty is broken and doesn't work.

4. The tripping delay of your home leakage insurance is greater than the delay of the main gate leakage insurance.

Hope it helps, thank you!

It should be a place where there is leakage, and ask a professional electrician to check it.

Explain that the protection switch tripped, resulting in a widespread power outage.

It is mainly caused by the unreasonable protection of the switch classification and segmentation, followed by the tripping caused by the damage of the branch switch.

This is to be switched, if you install a leakage switch in the whole building, it will trip.

The tripping of the entire building may be caused by excessive electrical load, and it is recommended that you take the following measures:

1.Check whether the load of electrical equipment in the home is excessive, especially high-power appliances, such as air conditioners, electric water heaters, electric blankets, etc., and try to avoid turning on them at the same time when in use.

2.If multiple power strips or extension cords are used, the number of patch strips or extension cords should be reduced appropriately to prevent the circuit from being overloaded.

3.Check whether the connection between the wire and cable and the plug is firm, and whether there is any looseness, aging, damage, etc.

4.If the above methods do not work, it is recommended to consult a professional electrician for inspection and treatment.

In addition, if the power load of the whole building is too large and causes tripping, it is recommended to contact the property or power supply department to increase the power supply capacity under the premise of ensuring safety to avoid affecting the normal power consumption.

If the electrical appliances in your home are turned on and the whole building is tripped, it may be that there is a serious grounding situation in your home, which is the situation of leakage.

The most effective way is to install an air switch with leakage protection at the entrance point of your home. This empty capacity should match the total current commonly used by the meter or device. The advantage is that the failure does not affect others and can be quickly dealt with by yourself!

Kiss! Hello, happy to answer your <>

If there is frequent tripping, you need to contact the local power company in time to find the specific cause and do repairs, so as to ensure the normal use in the later stage. The solution is as follows: 1. Check the electricity meter. Observe whether the electricity consumption of the meter corresponds to the recent electricity consumption at home.

If it is correct, it should be the problem of the air switch. If it doesn't, it may be an overload trip caused by line leakage. This is a more troublesome situation.

2.If it's a problem with the air switch, it may be that the thermal expansion sheet inside is broken. Of course, just change it to another one.

3.If the air switch is fine, it is necessary to consider whether the wiring at home is aging (it must be replaced after more than ten years.) Just replace the aging wiring.

4.Observe whether the meter is metering when the electricity is not used at home (when the air switch is closed). 5.

If the meter is constantly metering, there must be a leakage somewhere. If there is still a problem with the aging circuit, I hope mine can help you <>

Do you have any other questions?

The home often trips for no reason, the reasons are as follows, first of all, we first find out the reason for tripping, because home electricity is very common, we will also have a lot of main switches when installing the distribution box, first find out its problems, and then close the gates one by one to test the electricity, so that you can detect which one of the problems caused it to trip, find out the problem can be repaired to it.

After judging which electrical appliance and circuit is leaking, and then judging the circuit problem. Judging that there is a problem with the electrical appliances, the easiest way is to turn off the switch of the electrical appliances, and then pull on the electric switch, so that if it will continue to trip, it is the leakage of the circuit, unplug all the electrical plugs, and then open the electric switch, if it will not trip, it is the electrical leakage, not the problem of the line, this method is very simple, and it is easy to find out its problem, you must pay attention to your own safety when testing, do not be harmed. Find out the electrical leakage, or the line leakage in the maintenance, when we find out the electrical leakage or the line leakage to detect, if it is the electrical leakage, try to unplug all the plugs one by one, and then plug in one by one if there is no trip is good, just try again and again, if it is to trip, there is a problem with the line, and the line can be replaced with a new one.

If it is a problem with the electrical appliances, it is okay to repair the electrical appliances, when we rule out the tripping caused by excessive electricity consumption. Also consider its own reasons, if the reason for the long-term use of the switch is that its life to change a switch, if there is no leakage in the case of normal use, you can directly replace it with a new one, if there is a leakage warranty, don't use it again, replace it without this function.

Empty tripping is very common, its use is also unstable, so leakage treasure is still very important, leakage insurance plays a very important role in our lives, if there is leakage will trip by itself, if it is leakage of the components in the aging of the element, there will also be the above problems, it is necessary to repair it quickly. Another reason is that the air is too humid will also lead to tripping, because water seepage will cause problems in the circuit, and under this condition there will also be leakage leading to tripping, and if the line is aging, it will also trip, because in some houses with a long time, or second-hand houses will have relatively thin copper wires, which will age in this case of frequent use, and leakage will be life-threatening if the high-power switch is replaced, at this time we have to find a professional person to overhaul us.

Are you saying that the trip is irregular, and it has nothing to do with the electrical appliances, it is recommended to replace the circuit breaker, not yet, see if the leakage indication at the time of tripping jumps out, recall to check whether it is recently, ** water leakage, something has been moved, has there been an increase in power consumption, for example, the air conditioner used to turn on refrigeration, and now turn on heating.

There should be a leakage phenomenon in electrical appliances, and the leakage electrical appliances can be found out by the elimination method, and they can be used after replacement or maintenance!

1. The line is short-circuited and leakage, this phenomenon is relatively easy to judge, because as long as the machine is turned on, it will trip immediately. If you find that the line is short circuit or leakage, you should ask an electrician to deal with it. After checking for faulty shunt problems, power is sent after the fault is successfully repaired.

2. If the electrical equipment is leaking, you can use the voltage tester to check whether the metal shell of the equipment is leaking and find out the fault.

3. The line load is too large, and for large household appliances, such as air conditioners and washing machines, they must be routed separately, otherwise it is easy to trip during use.

4. The line is under-voltage, as early as the installation did not connect the lead wire firmly, and long-term loosening will cause the pile to heat up, oxidize, and burn out the wire, resulting in the line undervoltage.

There is always a trip at home for no reason, which means that your switch is fusing current or the setting is very unreasonable, or it may be that your pipeline line is in a place with grounding or short circuit.

Possible reasons, the wire diameter is too thin, the load is too large, the air switch load is too thin, the wire is damp, the insulation layer of the wire is damaged, and the wire is not connected ,...

That is the UMC phenomenon with unknown causes and indefinite times! It is not caused by the aging of the meter.

You can change the fuse to a thicker one, and then see if your home meter is small amps or the electrical power at home is overloaded!

If all of a sudden, there may be a problem with the fuse. You can ask an electrician to come and check the repair.

It may be that the line is aging, and there is no way to overload the electrical appliances, and the tripping situation is overpower protection, so it is better to find an electrician. At present, try not to use relatively large household appliances.

Causes of tripping at home.

It may be that the load is too large. The upper limit fuse is too thin to withstand such a large load. If it causes a fuse, the power goes out.

Hello, if you often trip for no reason, it is recommended to check the switch or find the person in charge of the power grid to check.

It may be that there are some places where the skin is worn and leaked, and the leakage will also trip.

The load factor is too low, and there are too many high-power appliances.

It is estimated that the voltage of some electrical appliances is unstable, and it is necessary to check them one by one.

If the electricity is normal, it is likely that there is a problem with the trip switch, and that one also needs to be replaced. It's not always and it's not bad.

The home trips at every turn, and sometimes it trips without electricity, and the old electrician explains the reasons for the trip in detail.

You still have a place to reconnect or connect to electricity, otherwise there will be no tripping for no reason, so you have to find a professional electrician to check the line for you.

Change to a high-power trip.

Many people have such an experience, the electric switch at home suddenly tripped, checked for a long time, and did not know if it was the first problem, why it tripped, mainly for the following reasons:

1.The switch does not match the load.

After buying a new high-power electrical appliance such as an air conditioner and water heater at home, you should check whether the switch matches the rated power, if not, you can ask a professional electrician to replace the matching switch.

2.Electrical appliances or lines leakage and short circuits.

Leakage and short circuit are one of the important reasons for tripping, it is recommended to cut off the circuit, ask the electrician to check the safety of the electrical circuit one by one, and eliminate potential safety hazards in time.

3.Aging lines.

After the line is aged, the load degree itself will be reduced, and when encountering hot and humid weather, the insulation is prone to failure, which will cause tripping, and a professional circuit technician should be asked to check the situation.

4.Aging of switches.

The leakage switch at home has been used for a long time, and the parts may be aged, which is easy to cause tripping for no reason, and a professional should be asked to replace the new switch to ensure the normal operation of the switch.

That's because the appliances in your home are overloaded!

First of all, check whether the voltage at the incoming end is normal, if the voltage is too high at this time, it is very dangerous, you must find a professional electrician for maintenance. You can also use the elimination method to carefully check which household appliance is short-circuited, check the short-circuited live wire and neutral line, measure the insulation resistance, check the short-circuit, and then take the correct way to deal with it.

What to pay attention to when using household appliances.

1. The use of household appliances is very important, first of all, we must first understand the switches of these appliances and understand how to use them. For example, if the washing machine is in use, turn on the power when it is in use, and turn off the power in time if it is not in use to avoid leakage in the wet.

2. If there is moisture on your hands, you must not touch the surface of the electrical appliance, it is very dangerous. Try not to bring electrical appliances into the bathroom, as moisture can get into the sockets and be dangerous when using them.

3. If the electrical appliance is burning, sparking or smelling, the first thing to do is to cut off the power supply in time.

4. If the electrical appliance is not used for a long time, it is best to unplug it, which can not only save electricity, but also ensure safety. Especially in thunderstorms, it avoids accidents such as electric shock or even fire in household appliances.

5. When using lamps and lanterns, cotton cloth and other combustible items cannot be placed under the lamp, because the temperature of the bulb will rise when the power is on, and it is possible to burn cotton cloth, towels and other items.

6. Switches and sockets are most commonly used, its quality is critical, and the switches and sockets used in the family must be purchased, the quality is only the best, and you can rest assured when using.

Summary: The above is about what to do if the home is short-circuited and tripped, I believe everyone understands! It is very common for short circuits to trip in the home, so in order to ensure your own safety, you must pay attention to the safety of electricity.
