Why do household leakage protection switches trip frequently?

Why does the leakage switch trip frequently? There are several reasons for this:

1) Poor installation. If the lead wire of each pile head is not firmly connected and loosened for a long time, it 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) There is a problem with the quality of the leakage switch itself.

Mismatch with 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 new installation or new use 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, you can send electricity. If a leakage or short circuit is found in the line, an electrician must be called to deal with it.

After the low-voltage circuit breaker jumps open, first disconnect all the branches, and then close the power transmission one by one. When a certain circuit is closed, the low-voltage circuit breaker cannot be powered, that is, the shunt is faulty, and this road should be disconnected and other shunts should be closed for power transmission. After the problem of faulty shunting is detected, the power is sent after repair.

4) The incoming voltage of the power supply is too high. This is very dangerous and generally occurs in the "three-phase four-wire power supply of residential cuddles." At this time, see if both wires are electrified; Second, see if the left and right neighbors also trip; Three, use a multimeter to measure the incoming line voltage.

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.

Senior electrician Qingdao Lao Zhu shared his experience.

Here's why:

1. The power of the electrical equipment is too large, exceeding the load capacity of the leakage protector 2, the line is short-circuited or leakage, and the line is checked for damage.

3. If the electrical equipment is leaking or damaged, use a multimeter to measure whether its insulation is normal.

4. The use environment is too humid.

5. The leakage circuit breaker is damaged.

There are 9 reasons for the leakage trip, and the old electrician will analyze it in detail, and he will be able to find the fault himself in the future.

Frequent tripping of leakage protection switches is also a common problem, and many people don't know what causes it, so we have to find out the reason. 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 point in your electrical circuit or appliance in your home, and it has nothing to do with electricity consumption. 3.

If it trips as soon as the light is turned on, my personal analysis is that if it is not a leakage switch, it is very likely that the neutral line in your home circuit is damaged or other reasons cause a grounding point. It is advisable to find an electrician to check the neutral line. 4.

Air switches can be purchased in general electrical equipment stores.

1. Leakage protectorLoad

If a leakage switch with a rated leakage current of 30mA has a leakage current of more than 25mA in the load, the leakage switch will trip. Since it is safe for a current of 25mA to flow through the human body, no electric shock death will occur; In the same way, there will be no danger to the line or electrical equipment, and the operation of the electrical equipment will not produce abnormal phenomena.

2. Poor installationIf the terminal posts are not firmly connected during the installation of the leakage protector, it will often lead to the heating and oxidation of the terminal posts 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.

3. There is a problem with the leakage protector itselfWhen the user buys the leakage protector, he should try to buy it from a reputable designated manufacturer or store, and do not buy the "three no" leakage protector from some self-employed people at a low price, which often outweighs the loss.

4. The leakage protector does not match the loadWith the increasing popularity of household appliances, the load current of many households has far exceeded the rated current of the leakage protector on the line, causing the leakage protector to trip. 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.

5. Line leakage and short circuit: If the leakage protector is tripped due to leakage or short circuit 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.

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

1.Short circuit, due to the aging of the wire, or the human accident to connect the live wire and the wire directly together without passing the load. Phenomenon: instantaneous tripping, that is, as long as there is a short circuit, the air will be automatically disconnected at the first time.

2.Overload, due to the advent of summer, too many household appliances, and the load of the air switch and the wire diameter of the wire is too thin, resulting in the air opening due to overload and disconnection. Phenomenon: Delay, tripping after 5 minutes of electricity.

Reason] You can look at high-power electricity: electric kettle, air conditioner, whether you have turned on a few air conditioners, induction cooker, garment steamer, vacuum cleaner, these are all high-power household appliances. If you open it together, the line will trip if it can't stand it.

Solution]1 . You can properly turn off a few appliances that are not urgently needed.

2.In the case of Lu Yun, replace the air opening with higher power, if the wire diameter is not enough, and you want to replace it, then the wire is thicker.

Hope it helps! Have a great day! If you think it is helpful to you, please give it a thumbs up.

Question: The circuit is empty and can't be pushed.

Second, there is the possibility of overload and short circuit.

Third, the leakage reset button popped up.

Fourth, the leakage protector is broken.

The leakage protector trips as long as the power is sent, and it can't be closed at all, and the old electrician teaches you to analyze the trip fault.

After replacing the leakage switch, it is normal, which is obviously the poor performance of the original leakage switch, which leads to malfunction.

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.

1) Poor installation. It may be because the pile head lead is loose, if left unchecked, the pile may be hot, burned out of the lead and other phenomena, it needs to be connected firmly.

2. The power supply voltage is too high. Use a multimeter to detect the voltage of the power inlet, if it is really because the voltage is too high caused by the switch tripping is very dangerous, it will burn out the electrical appliances, and serious will cause accidents such as fires, endangering life safety.

3. The wire leaks due to moisture and other reasons, causing tripping. In the wetter season, pay attention to whether the electrical circuit at home will be affected by the humid weather. In addition, in the bathroom, where there is more water vapor and higher humidity, will the line leak due to moisture.

It is necessary to do a good job of drying the circuit.

You changed the circuit yourself, right?

If so, did you not add a sleeve when pulling the wire, nor did you use a double-sheathed wire, and it was embedded in the wall?

If so, there may be leakage on the wall in the line, causing the leakage protection switch to trip.

If it is not for the above reasons, you can see if there is a neutral line connected to the lamp head of another switch, and if there is, it will also trip.

None of the above is the case, that is, there is leakage of electrical appliances connected, or in the three-phase socket of the wall switch, the neutral line and the bottom line are reversed.

It is estimated that the aging belt motor and other products in the family for more than ten years have unqualified insulation performance, resulting in leakage. For example, we have a refrigerator, air conditioner, and ......
