What is the reason for the old tripping of the leakage protection switch at home, and the old trippi

Friend, you first solve the socket of the two live wires, if the leakage switch is still tripped, then I suggest you change the leakage switch to try it, I estimate that your problem is that the leakage switch protection circuit is faulty or your leakage switch capacity is too small, I suggest you change a slightly larger one. If it is still the same, then the main check whether there is any leakage of your equipment load, if there is still no leakage of equipment and load, then you disconnect the load at home to try it, this method is very practical, you may wish to refer to it.

In summer, the electricity consumption is relatively large, if the possibility of leakage of household appliances is ruled out. In general, there are two possibilities: one leakage protection switch is small, (the simplest algorithm, multiply the power of all household appliances by 2, and then multiply by 4, which is the size of the number on the leakage switch.)

For example, 16a or 32a and the like) two weather reasons and then add wire insulation problems, (insufficient insulation) resulting in intermittent tripping. To sum up, if it is convenient, find a professional electrician to see, and then replace it with a leakage that is a little larger than the original leakage.

That's right, roughly 1kw is equal to 2a).

It is very likely that as you said, the wet weather causes the wire to leak, but it cannot be ruled out that the power consumption is large, and the leakage switch can not be loaded to cause tripping.

1. The wire is damp. There are always a few months of the year when it is humid, which means that the humidity in the room will also be high, and the wires are likely to leak due to moisture. Especially in a humid space such as the bathroom, if the wires are constantly in a damp state, it is very easy to leak electricity, so we need to check the circuit regularly.

Leakage due to moisture in the wires is the first reason why household leakage protectors often trip.

2. Improper installation leads to tripping. In addition to tripping the household leakage protector due to moisture, if it is not installed properly at the time of installation, the household leakage protector is also likely to trip. For example, if the lead wire of the pile head is loose, if it is not found, the pile head may heat up and burn the lead, which will also lead to the tripping of the household leakage protector.

Therefore, when installing a leakage protector, it is important to check it carefully to ensure that there are no problems.

3. The power supply voltage is too high. For any kind of household appliances, they have a scope of application, if beyond this range, it will complete damage to the electrical appliances, and even lead to some irreversible consequences. If the voltage is too high, the household leakage protector has a great chance of tripping, once the leakage protector trips, then the electrical appliance is burned out is a trivial matter, and the disaster will be troublesome.

1. The leakage protector is not in place when it is installed, so that it has poor contact, which leads to the undervoltage of the circuit and trips the protector. 2. When purchasing the leakage protector, I did not pay attention to its quality, and bought three no products, which made the quality of the product itself not up to standard, and there was a tripping situation 3. The leakage protector does not match the load, if the current of the load has been greater than the rated current of the leakage protector itself, there will also be a tripping problem. 4. If there is leakage or short circuit in the line, it will also cause similar problems.

5. When the power supply enters the line, the voltage is too high, which makes the leakage protector appear in this situation.

I hope it can help you, and if you are satisfied, give it a thumbs up! Your support is my biggest motivation to move forward. Thank you! I wish you a happy life and a happy day. ❤️

Four reasons. 1. Poor installation of leakage protector If the terminal posts of the leakage protector are not firmly connected during installation, it will often lead to heating and oxidation of the terminal post for a long time, so that the wire insulation layer will be scorched, and accompanied by the smell of ignition and rubber and plastic burning, resulting in undervoltage of the line and tripping the leakage protector. Second, the leakage protector itself has a problem when buying the leakage protector, should try to buy it from a reputable designated manufacturer or store, and do not try to buy the "three no" leakage protector from some self-employed individuals at a low price, which often outweighs the loss.

3. Mismatch between leakage protector and load With the increasing popularity of household appliances, the load current of many families has far exceeded the rated current of the leakage protector on the line, resulting in the tripping of the leakage protector. This situation generally occurs in the use of high-power household appliances such as air conditioners and electric kettles, and the problem can be solved as long as a matching leakage protector is replaced. 4. Leakage and short circuit of load or lineIf the leakage protector is tripped due to leakage or short circuit of the load of household appliances, as long as the faulty household appliance plug is unplugged, the power can be re-transmitted; If it is a leakage or short circuit in the line, it is relatively tricky, and some simple faults can be solved first, so that some lines can be temporarily restored to power transmission.

1. The installation process is not in place, and there is poor contact. 2. There are certain problems with the product itself. 3. There is a mismatch between the leakage protector and the load.

4. There is a leakage and short circuit in the line. 5. When the power supply enters the line, the voltage is too high. In the above situation, it is very easy to cause the leakage protector to trip.

Explain that there is a leakage of electricity, especially in the kitchen, some places are damp, it will trip, find an electrician to check.

There are three main reasons why the leakage protection switch always trips, the first is that the electrical equipment leaks, so the switch trips; The second is that the line joint has poor contact, and it will also leak and trip; The third is that there is a problem with the quality of the leakage itself, and the wrong detection of the electrical signal leads to tripping.

It may be that the installation is poor, because the lead wire is loose in the middle of the way, and if it is left unchecked, the pile may heat up and burn out the lead, and it needs to be firmly struck. If the power supply voltage is too high, if the switch trips because the voltage is too high, it is very dangerous, and the new color burns out the electrical appliances in serious cases, which will cause accidents such as fires and endanger life safety.

It may be that there is a possibility of leakage in some part of the home, otherwise his leakage protection switch will not trip, you have to observe what is the leakage caused by the home.

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

Leakage switch and load mismatch: 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.

Electrical appliances or lines leakage and short circuit: 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, you can send power. If a leakage or short circuit is found in the line, an electrician must be called to deal with it.

The voltage of the power supply incoming line is too high: this is very dangerous, and it generally occurs in residential buildings with three-phase four-wire power supply. Do not forcibly close the low-voltage circuit breaker, otherwise it will burn out the electrical appliances at least and cause a fire at worst.

If there is a problem with the quality of the leakage circuit breaker: check the quality of the leakage circuit breaker first. One is to check the leakage tripper, generally with the test button to test, when pressing the test button, because of the I1 shunt, so that I1 and I2 are not equal, that is, the phasor sum is not zero, therefore, the leakage circuit breaker should act, requiring the trip sensitive; The second is to check whether the leakage circuit breaker can be closed in the no-load state, if it cannot be closed, the leakage circuit breaker is faulty, can not be used, and should be replaced (self-repair is not recommended).

Leakage circuit breaker wiring error: check whether the phase wire of a certain electrical equipment is connected to the front of the leakage circuit breaker, so that part of the load does not pass through the leakage circuit breaker, so that the leakage circuit breaker n line current is greater than the phase line current, so that it trips, or even can not close the switch.

In this case, there may be leakage or poor contact faults; It is also possible that the main gate capacity is small and trips when the power consumption is overloaded.

There are generally two reasons for tripping, one is leakage tripping (if you have a leakage protector installed in your home), and the other is overload tripping, so you have to pay attention to it first

1. If you usually do not jump and trip or are easy to trip when using an electrical appliance, it means that the electrical appliance has a leakage or a place with poor insulation; 2. If a certain line is used as long as it is used, that is, a certain line jumps once it is supplied with power, it means that there is a leakage of this line; 3. If an electrical appliance does not jump at the beginning when it is used, but jumps after a while, it means that the insulation of the electrical appliance is aging, and the thermal stability deteriorates and leakage occurs; 4. If it is when using electrical appliances with relatively large power consumption or more electrical equipment in use at home, it trips at this time, it means that the rated current of the tripped air switch (PVC air switch or leakage protector for household) in your home is small, and you should replace it with a suitable leakage protector with a relatively large rated current.

The leakage total protector trips, and there is only one situation, that is, there is a leakage in your home, which is usually inexplicably tripped, and it is likely to be because of the socket in the wet place of the bathroom or kitchen. Leakage caused by moisture in the internal wiring. It is recommended that you check the electrical sockets in the bathroom or kitchen.

Hope mine is helpful to you, hope.

Load or line leakage and short circuit: If the leakage protector is tripped due to leakage or short circuit of the load such as household appliances, as long as the faulty household appliance plug is unplugged, the power can be re-transmitted; If it is a leakage or short circuit in the line, it is relatively tricky, and some simple faults can be solved first, so that some lines can be temporarily restored to power transmission.
