Tripping electrical circuits at home? What s the deal with frequent tripping of electrical circuits

The trip you are referring to is the trip after a few minutes after turning on the air compressor, which is the overcurrent trip of your leakage switch, not leakage or short circuit. Leakage or short circuit trips in just 1-2 seconds. The air compressor has high power and high electric current.

The tripped switch couldn't withstand it, and finally tripped. If you didn't trip before, maybe this switch is at the critical point of tripping or your power is not so large. Hope it helps.

It shouldn't be a loophole, if it's a loophole, it keeps tripping and can't close. "Signs of a little melting of the wire", maybe even if it was normal before, maybe the circuit is overloaded, but it is not reflected, now the wire has been used for a long time, so that the life of the wire is shortened, the phenomenon of aging, the long time is the wire heating, if this is the case, for the sake of safety, change the wire to try.

1.Check that the main power supply wire has the phenomenon of heating when the air compressor is turned on, 2Check whether the input and output are loose.

3.Check whether the air compressor is short of oil, resulting in an increase in current.

4. Use the method of eliminationTurn off the air compressor first, check whether it trips, and then turn on the air compressor alone, 5 wires may be aging, and finally 4 square VRV cables, it is not easy to have joints in the middle.

Hope it helps.

If the current is overcurrent, measure the current.

The place where the switch wiring is in poor contact.

Check the terminals and clean the heat dissipation part of the air compressor.

The load is too heavy, why do you install an air compressor at home?

1. The load of electrical equipment is too high.

Large electrical equipment such as air conditioners, refrigerators, and water heaters have a large input power, so they must be routed separately when transforming the circuit and cannot be shared with other electrical appliances, otherwise it is easy to trip and lose power when it is turned on at the same time.

2. Short circuit of load line.

If it is a short circuit, it will trip at the moment of turning on the machine or the moment of turning on the air switch, that is, it will not be able to send power at all.

3. Load leakage.

This phenomenon is similar to the previous one, there is generally a leakage switch in the distribution box at home, and if leakage occurs, it will automatically trip.

4. Air conditioning problems.

For example, in the heating process of the air conditioner, the current flowing through the switch is too large, and after a few minutes, the switch heats too much, and it will automatically trip with a delay.

5. Poor installation.

If the lead wire of each pile head is not installed firmly and is loose for a long time, it will cause the pile to heat and oxidize, and burn out the outer insulation layer of the wire, resulting in sparks and burnt smell, resulting in undervoltage of the line, resulting in empty tripping.

First, the line is overloaded, and large household appliances are not wired separately.

Many families will want to save lines and money when decorating, and put high-power sockets such as air conditioners and water heaters and ordinary sockets together to run the line, which is a very serious problem.

If the reserved number of wires is sufficient, then there is no need to replace the wires, and directly replacing the larger air switch can solve this problem.

Second, there is a short circuit at the load end, which will jump as soon as it is sent or jump after a while.

That is to say, there is a short circuit on the electrical end, such as water heaters, kettles, refrigerators, air conditioners, these household appliances will have a short circuit.

For example, the working mechanism of the refrigerator is to power on for self-check, after the self-test is completed, it can be preheated, and then the compressor starts to work, if the compressor is short-circuited, it will trip only when the compressor is working, which is why it will trip after a while, and the same is true for air conditioners.

3. The load end is grounded, and there is leakage.

There is also a situation of leakage of household appliances, which is also more common in the family, because of the high humidity in summer, the switch box of many families has not been sealed, and the water flow and water vapor are easy to flow into the switch box through the wall, and then there is a leakage short circuit to the ground.

Don't worry about this situation, first disconnect all the air opening, and then send power all the way to the experiment, that all the way to jump away is which way there is a problem, disassemble the switch box in a power failure, use a hair dryer to dry, cover the switch box, and then glue and seal it to continue to use.

Fourth, the air switch itself is a problem, and the contact is poor.

There is also the quality problem of the air switch itself, so it is recommended to try to use the best and big brand household appliances when selecting materials for decoration to avoid problems and need to be replaced.

It may be the cause of leakage and undervoltage, but there is also a possibility that the circuit breaker itself is broken. Therefore, if the circuit breaker trips frequently, you can start to find the cause from these aspects, in order to solve the fault as soon as possible and restore the power supply.

Hello, the frequent tripping of the circuit at home is generally because the input power of large household appliances is too high, so when installing the circuit, large electrical appliances at home must be wired separately, such as refrigerators, air conditioners, etc.; If the home is equipped with a leakage protection switch, the load line will trip once it leaks; When the lead wire is loose, it will cause oxidation or even heat generation of the wire, resulting in frequent tripping of the circuit.

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

Frequent tripping of electrical circuits at home is caused by short circuits.

For example, if the rice cooker is poofed, water enters the plug, causing a short circuit in the rice cooker, water entering the circuit of the washing machine, and there may be an aging of the wiring, resulting in a short circuit in the wire. These are all possible. It is necessary to carefully check the circuit to rule out the cause, and then close the brake without a problem.

The circuit in the home trips frequently, so it is very likely that the line is leaking in some places. If you can't find it yourself, you should find a professional electrician to fix it.

Each switch joint is inspected for a piece, and the contact is poor due to the oxidation of the wire head, and it is reinstalled after rust removal; Second, some low-quality air openings are poor, the plastic is aging or the terminal is seriously rusty. It is recommended to change the brand to open empty, and it will not take much money.

If the circuit in the home trips frequently, you should first check whether the switch is loose, and be sure to tighten the air switch.

It is estimated that there are short-circuits in some places. You find a professional master to check it carefully.

There are three reasons for the old tripping of the electric switch: 1. Caused by overload; 2. Caused by short circuit; 3. Caused by leakage.

caused by overload. In the use of some electrical appliances, for example, the wire is a square lighting wire, but it is used in high-power appliances. The power of the appliance greatly exceeds the load on the wires. At this point, the safety device of the switch is activated, causing a trip.

Caused by short circuits. At the interface where the wires are connected, sometimes they are not connected firmly, or if they become loose after a period of use, which can cause a short circuit. At this time, the safety protection device is opened, and the power is tripped and the power is cut off to prevent fire.

3. Caused by leakage. There will be a leakage protection device for household electricity, and as long as the current difference of the fire zero line exceeds 30 milliamperes, it will touch the safety protection and cause tripping.

The old trip must be a fault in the outgoing circuit of the home, which touches the protection device. Therefore, it is important to find a professional to find out the cause and solve it in time to ensure safety.

1. The air switch amount copy fixed current selection error BAI, that is, the line and DU air switch do not match.

For example, a normal line should not exceed 6A, but the air switch used for DAO is disconnected at 4A, and the other is that the normal line should not exceed 6A, but the air switch will be disconnected at 8A, resulting in circuit fusing or even fire.

Second, the electrical placement does not conform to the indoor circuit planning, for example, the indoor was originally divided into four power supplies, each of which is 6A, and the design of high-power electrical evenly distributed on each road, but the user himself used a variety of high-power electrical appliances, and on the same road, resulting in overload.

If the location of the appliance cannot be changed, either it is not turned on at the same time, to.

Change the indoor circuit.

If the wire diameter is enough, there is a problem with the brake, and the lower end of the brake screw is not tightened, and the socket will trip if it is deformed for a long time, and the contact is poor.

If not, turn on the equipment separately whether the equipment trips, or not: change to a larger switch or pull a separate route to the device. If the above reasons are ruled out, it may be that the local voltage is unstable due to frequent tripping during a certain period of time.

It may be leakage, see if your gate is with a leakage switch.

It is also possible that you have too many electrical appliances and the current is too large, so change to a switch with a higher current.

It's time to change the wires. Because the line also has an old time.

Electricity leakage is caused by checking all the appliances in your home.

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. 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, 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 finding out the problem of faulty shunting, it will be repaired and then sent to power.

4. The incoming voltage of the power supply is too high.

This is very dangerous and generally occurs in residential buildings with three-phase four-wire power supply. 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.

5. There is a problem with the quality of the leakage circuit breaker.

Check the quality of the RCB first. One is to check the leakage tripper, generally with the test button to test, according to the test to press the hidden 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 weighing bureau state, if it cannot be closed, the leakage circuit breaker is faulty, can not be used, should be replaced (do not advocate self-repair).

6. The wiring of the leakage circuit breaker is wrong.

Check whether the phase wire of a certain electrical equipment is connected to the front of the leakage circuit breaker.

You can unplug some electrical appliances that are not urgently needed to reduce the load on the circuit. If the wire is damaged and trips, you need to find a professional electrician to repair it. If there is a short circuit in the load line in the home, or if the high-power appliances such as water heaters and air conditioners are turned on at the same time and cause tripping, you can unplug one of the appliances.

1. You can unplug some electrical appliances that are not urgently needed to reduce the load of the circuit.

2. If the wire is tripped due to damage, you need to find a professional electrician to repair it.

3. If the load line at home is short-circuited, or if it trips due to high-power electrical appliances such as water heaters and air conditioners being turned on at the same time, you can unplug one of the electrical appliances.

1. If you are the only one who trips and has no power, first check whether the leakage protection switch at home and the air switch under the meter are damaged. If there is no damage, send the air switch by yourself, and it will be electrified;

If you will not check the line, or you have checked yourself and confirmed that it is the fault of the power supply company's property rights, you can call the service of the power system **95598 or report for repair through the power company's Weibo and interaction**.

2. If there is a power outage in many households around, you can immediately call the service of the power system **95598 to report for repair, and the power company will check the fault repair record and report for repair in time.

<> "1. What should I do if the circuit at home always trips?"

First of all, you need to find the cause of tripping, if the leakage protector can't be pushed, it means that the leakage protector is not normal, and this situation needs to be replaced with a new one. If the leakage protector continues to trip not long after pushing it on, it indicates that the line is faulty and you need to contact a special electrician to come and repair.

Second, what is the reason why the circuit at home keeps tripping?

When actually dealing with the trip problem, it is necessary to find the specific cause, and then prescribe the right medicine, the following are some common problems.

1. Due to the high power of large household appliances, the rest of the circuits cannot be connected when connecting the circuits, and a separate wire needs to be configured, otherwise there will be frequent tripping.

2. If there is a short circuit in the line of the load, it will also trip when we turn on the electrical appliances for use, and there is no way to send power.

3. Load leakage is similar to the previous situations, but only when there is leakage, it will trip, if the distribution box at home is pz30, the leakage will trip, because this distribution box is with a leakage switch.

4. The air opening is abnormal, if the rated power is close or even exceeded, the problem of tripping will occur due to excessive current.

5. When workers install the circuit, if the slag stool line is not stable, once it is used, it will become more and more lax, so that the electrical appliances will be oxidized.
