Why do you keep jumping the main gate? Why is it tripping

Measure it with a clamp meter and trip frequently.

The switch will be known.

If the current has not yet reached the calibration current of the switch.

Just tripping, that's the switch problem. If the current is too large and trips, it is necessary to check which one is using too much electricity.

However, according to your description, there is no increase in the use of electrical appliances, and the wiring of the switch is normal, the easiest thing is to directly replace the switch (**big brand). Let's take a look.

According to the situation you said, it didn't trip before, but now it always trips, it is recommended that you change it to an empty opening, and it is recommended to change the A number slightly larger, because no matter what the empty opening is, it also has a life.

It should be the main gate overheating protection and drop off. If the terminal is not loose and heated, it is good to change to a larger circuit breaker under the condition that the power line is not overloaded.

The main gate of the distribution box is empty open, and the opening is leaky, why do you always jump the main switch? I see.

It is estimated that the wire of that house may be aging and leakage

You should find a power company to jump the main gate, right?

Here's why:1. The connection of the lead wires of each pile head in the electric gate is not firm, resulting in a short circuit of the line and causing tripping.

2. The household electrical load is greater than the rated current of the circuit breaker.

3. The electric switch trips due to leakage or short circuit of electrical appliances or lines.

The principle of electric switch trippingThe reason why the electric switch trips is to play a protective role, because the line with excessive voltage is very dangerous, if people touch the leakage place, an electric shock accident may occur, so the electric switch will trip itself to cut off the power supply.

Then its principle is that when the voltage is too large, the output current is greater than the input current, there will be an induced voltage formed, once the induced voltage is formed, the force that pushes the electric switch will appear in the fine structure of the electric switch, so that the switch trips.

If it trips frequently, there must be something wrong with the circuit and needs to be repaired. Causes of tripping of household appliances.

1.Due to the heavy load of household appliances, exceeding the rated load is an overload protection trip.

2.Because some appliances are grounded, leakage protection trips. You can gradually plug in the power or turn on the appliance. When you turn on an electrical appliance and it trips, the first thing to check is whether this is suspected of leakage, whether it is a high-power electrical appliance, and the cumulative load exceeds the rated load.

3.Check if the leakage can be turned off or unplugged from all other appliances, and turn this one on separately. If it is turned on normally, it means that there is no leakage. If it also trips, the problem is with this device.

4.If the device is not leaking, it is a load issue. You can first look at how big your on-load is (also pay attention to the allowable load of the meter), and then calculate the total power of the appliances you use when you turn on (whether you calculate the power of the refrigerator and air conditioner when it is started by the compressor).

If there is indeed an overload that cannot be adjusted and avoided, it is necessary to consider the problem of expanding the meter and replacing it.

5.Finally, if none of the above problems exist, then replace it with a new one of the same capacity and see if the empty one is invalid or allergic.

The reasons for the old tripping are as follows:1. The tripping caused by the short circuit of the electrical appliances can be checked one by one, and the damaged electrical appliances can be repaired to solve the problem;

2. The circuit load is too large, when multiple electrical appliances are used at the same time, it will cause overload, and the meter switch will automatically trip, and you can buy a higher power meter;

3. Voltage instability, voltage instability is very common, and only need to buy a voltage regulator to solve it.

1. The line is short-circuited. The air switch can be used for a period of time when it is pulled up, and the situation occurs is that the air switch trips, but the leakage protector does not work. So this kind of is a conditionally triggered short-circuit.

2. The air switch does not match. This circuit uses high-power electrical appliances (air conditioners, washing machines, water heaters, bath bombs, etc.), but it is easy to trip if the load is equipped with low power and empty opening. If the total power exceeds the rated range for the empty opening, then tripping is also possible.

At this time, it is necessary to replace the air opening with higher load power.

3. Loose wiring or poor contact of the wire. This situation is also one of the common reasons for air tripping, you can break all the air opening, check the air opening wiring one by one with a screwdriver, and tighten one by one, just in case.

4. Circuit breaker damage is rare, you can disconnect the circuit breaker to remove the load first, if it still can't be closed, it means that the circuit breaker is damaged, then you can replace the same type of circuit breaker.

The reason for the circuit tripping.

1.Large electrical appliances such as water heaters and air conditioners: For electrical appliances with large power, they must be wired separately when decorating.

Otherwise, it will be very easy to trip in later use. 2.Load line short-circuit:

If the load line is short-circuited, it will trip at the moment of power on or the moment of opening the empty opening, that is, it will not be powered at all.

3.Air opening problem: This is the rated load power, and it is an ordinary C-type circuit breaker (see if the tripped switch has the word "C16"?) What is the maximum power of air conditioner heating? If it is close to or greater than 3 52, it means that in the heating process, the current flowing through the switch is too large, and after a few minutes, the switch is overheated, and it will automatically trip with a delay.

Should be. The line is grounded or short-circuited or over-incompatible, and the amount of electricity is relatively large, which will lead to tripping careful maintenance of the circuit, and then replace some matching wires, do not overload so that it will not be unable to trip.

The reasons for tripping are excessive load, short circuit in the indoor wiring, leakage of electrical appliances and damage to the switch itself. To check the cause of the trip, you need to cut off the power or find a professional electrician, pay attention to safety.

If the power is large, the input current exceeds the rated current of the switch, or there is the possibility of mixed electricity, it will generally trip old.

There are many reasons for the leakage switch tripping, such as electrical short-circuiting, wire damage, leakage switch damage will cause tripping, it is recommended that you do not understand or find a professional to troubleshoot the fault for maintenance.

Line leakage, short circuit, excessive power consumption, switch rated current is too small, switch failure and other reasons will trip.

Why did the old trip trip? There may be various reasons, one is that the line worn in the line during the decoration is too thin, and the other is that it may be connected to the electricity? So it's good to keep tripping.

The old tripping is due to the aging of the line, damage or poor line contact, resulting in excessive current load tripping.

Hello: The electrical equipment you are using is too powerful, and the air switch (over-current protection is too small).

Short circuits, leakage, and overload are all possible.

Why do you trip at every turn? What are the causes of tripping? Here's what the old electrician had to say.

A short circuit or a large amount of power.

Frequent tripping of household circuit breakers is mainly due to the following reasons:

1. Poor installation: the lead wire of each pile head is not firmly connected and loosened for a long time, which will cause the pile to heat and oxidize, burn out the outer insulation of the wire, and emit sparks and burnt smell, resulting in undervoltage of the line and air switch action.

2. The leakage switch does not match the load: the actual electrical load of the household is greater than the rated current of the low-voltage circuit breaker on the line. It generally occurs after the installation or addition of high-power household appliances such as air conditioners and electric water heaters. The matching air switch must be replaced.

3. Leakage and short circuit of electrical appliances or lines: When it is found that the electrical appliances used are leaking, as long as you unplug the electrical appliances with leakage faults, and then close the low-voltage circuit breaker again. After the low-voltage circuit breaker jumps open, first disconnect all the branches, and then close the power transmission one by one.

Tripped the method of restoring electricity:

You should check the wiring and electrical appliances first, generally there is a small twist on the panel of the leakage protection, it will bounce up when the leakage protection action, press it back first, and then close the switch.

Another thing to pay special attention to is that if it is a trip caused by electrical overload, we must first power off the relevant electrical appliances so that they can be restored.

Electricity is needed everywhere in our daily life, and if the electrical circuit in our home often trips, it will have a great impact on our daily life. When the home circuit trips, when we are carrying out maintenance, we usually need to determine the cause of the circuit trip at home, and carry out targeted maintenance treatment, so what is the cause of the total trip of the circuit at home? Next, I will briefly introduce to you what the total trip is.

1. The total trip of the circuit may be due to the problem of short circuit of the wire, once the wire has a short circuit problem, the empty switch will trip instantly, so as to protect the safety of home appliances. If the wires at home are short-circuited, you can first unplug all the electrical appliances at home, and then plug in the electrical plugs in turn, find the fault point, and finally repair the wires.

2. The total tripping of the circuit at home may also be caused by the mismatch between the total power of the wires and the electrical appliances. If the size of the wire we use is too small, the current it carries is also small, and when multiple electrical appliances are used at the same time in the home, it is easy to cause the wire to overload and trip. When we buy wires, we should choose the right wire products according to the total power of the electrical appliances in this circuit, and the power carried by the wires is slightly larger.

3. The total tripping of the circuit at home may also be due to the leakage of the line caused by the failure of the electrical appliance, and the line will automatically trip when the air is opened to detect the leakage of the line. We can unplug the damaged electrical appliances and ask professional maintenance personnel to repair the electrical appliances and troubleshoot the fault. The total tripping of the circuit at home may also be caused by the instability of the voltage at home, which may cause the illusion of high-power load of the wire, resulting in empty tripping, we can use a voltage regulator to stabilize the voltage, or report to the local power bureau.

Many trips are caused by leakage protection, and a few are caused by overload or short circuit. A very small number of leakage protectors are caused by the wrong installation and wiring, first disconnect all the electrical appliances in the home, do not use all the sockets, and then connect them one by one until you find the problematic appliances, which can be solved. If it is not leakage, overload, short circuit fault, or leakage of dark wires in the wall, you have to find the help of an electrician.

There are many kinds of tripping: one is overload tripping, and the power of the electrical appliances used exceeds the empty opening capacity; The second is short circuit and leakage tripping, indicating that the line or electrical appliance fault causes tripping; The third is the aging of the empty opening, which causes its own problems and cannot be closed.

The trip may be that the voltage is unstable, and it is best to ask someone to take a look and solve other problems by the way.

1.The first step is to check the switch or leakage protector in the distribution box.

1) Look at the situation in the subject's home, and the total gate trips every time.

2) We first inspect the main switch, the easiest way to do it.

3) If it still trips after replacing, then it is excluded.

2.The second step is to check the condition of the household appliances in our home.

1) This step is more troublesome, so you have to check us one by one.

2) The most likely problem with the electrical appliances in our home is:

3) Then other household appliances follow this method.

3.Step 3: Check that there is a problem with the wiring in your home.

Home circuits always trip, what are the reasons for tripping? Thanks to the experience sharing of old electricians, the knowledge is increased.

1. It is best to find an expert to check the leakage switch, if there is a fault, it must be replaced with a new one, which is the most important protection for residential electricity, and you must not be careless.

2. If there is no problem with the leakage switch after inspection and it always trips, it means that there is a grounding position in your electrical circuit or electrical appliance Zheng He, which has nothing to do with electricity consumption.

3. If the light is turned on, it will trip. If it is not a problem with the leakage switch, it is likely that the neutral line in your home circuit is damaged or there is a grounding point due to other reasons, and it is recommended to find an electrician to check the neutral wire.

4. The leakage switch can't be turned on The leakage switch tripping is that the leakage current of the home appliance is a little large, resulting in leakage, and the leakage current of the general household leakage switch is less than 30mA. If you don't jump, then there is a security risk. If you skip:

You first knock down all the other switches, and then send the leakage switch (if you can't send it, the leakage switch is broken), and then send it all the way, if you send it to that jump, it is the electrical leakage under the control of the switch, check what the problem is.
