Why does the socket trip as soon as it is connected

There are generally two reasons for this situation, one is that the electrical appliance has been damaged or leaked, and you can try to replace it with another good electrical appliance. The second is that the wire in the socket is connected incorrectly. Generally, the neutral wire and the protective ground wire are connected incorrectly, and it can be reconnected.

1.You don't need to change the wire connected to the socket, you can tighten the screws of the three fixed wires.

2.After confirming the tightening, do you plug in other electrical appliances to see if they trip? For example: hair dryers, chargers, etc.

3.If it doesn't jump, it means that there is a problem with the appliance you plugged in before, and it may be internally short-circuited or grounded.

If it jumps, it means that you have a problem with this socket, change the socket, if it still jumps, then it may be that there is a problem with the leakage switch, tighten the wires on the leakage switch, and replace it if it doesn't work.

Generally, this is not a line problem.

1.Check the plug board, there is something wrong inside. 2.The three wires can not be connected randomly, if the electrical appliance is a two-end bolt, you can leave the ground wire in the middle empty. But you can't just plug two holes.

However, you have a problem with electrical appliances, or your socket may be short-circuited in the internal wire. It's best to replace the socket and you're good to go.

The correct connection of the power cord is the left zero and the right fire, and the ground wire in the middle of the top cannot be connected wrongly.

Are you plugged with wet water? There is also a short circuit inside the appliance you are using.

Dude, don't fool around, what are you going to do with electricity. It must be the wrong answer, find an insider to take a look, this little thing in a class is not your money.

The socket is broken, let's change it.

There must be a short circuit in the socket.

It could be that the appliance you plugged in is leaking.

You can change an electrical appliance to give it a try, if it doesn't trip, it means that the original electrical appliance is leaking and needs to be repaired;

If it still trips, the socket is broken, and the socket is replaced.

It may be because the power of the electrical appliance is too large, the current generated is too large, or the fault of the appliance itself, thank you for reference.

1. The electrical appliance connected by the plug is short-circuited or leakaged. 2. The electrodes or wiring in the socket are loose, and there are sundries in the socket 3.

It is possible that there is water inside, or there is a leakage of electricity. Stay safe. The leakage protector will trip automatically.

1. The socket is wired incorrectly, which may cause tripping when using.

This is usually the case when a newly installed socket, such as the neutral and ground wires are reversed. If the upper circuit breaker is a leakage protector, it will be judged as leakage tripping when it is used.

2. There is a short circuit or leakage fault inside the electrical appliance, and it will also trip when plugged into the socket.

The leakage protector plays the function of overload, short circuit and leakage protection. If the electrical appliance used has a short circuit or leakage fault, it will cause the circuit breaker to trip when it is used.

3. Overload tripping.

For example, the circuit breaker of the branch is a 10A air switch, if the power of the electrical appliances on this branch exceeds it, the empty opening will overload and trip when it is used.

Suggestion: Circuit breaker selection method for socket branch: There are too many electrical appliances in the socket branch, and it is best to use a leakage protector. P total 220 = i total, the rated current of the circuit breaker can be selected as the total number of i.

4. The line of the socket branch is leaking.

If there is leakage of the wire of the socket branch, the leakage protector does not trip because the leakage current of 30 mA is not reached, but after plugging in the electrical appliance, the current will change and trip immediately.

It may not be a problem with the socket, check whether the plugged electrical appliances or the lines connected to the socket are less than 3 trillion ohms, and use a 500 volt shake meter to detect it after the power is off. It is also possible that the empty opening or missing warranty itself is a faulty part, and it will be fine after replacement.

The socket will trip after a while, and in the face of this situation, it is necessary to observe according to the actual situation: after the circuit breaker trips, observe the state of the circuit breaker. If the reset button of the circuit breaker is prominent, it proves that the circuit breaker is tripping due to leakage; If the reset button does not protrude, it is due to an overload trip.

Answer: Generally, it is now equipped with or has the function of leakage protection, and the old tripping will generally be due to two reasons, 1. Because the heavy load exceeds the rated load, it is an overload protection trip, 2. Because some electrical appliances have grounding phenomena, they trip due to leakage protection. You can gradually plug in or turn on the electrical appliances, and when you turn on an electrical appliance and trip, you must first check whether there is a suspicion of leakage in this one, or a high-power electrical appliance that has accumulated to exceed the rated load. Check whether there is leakage can turn off or unplug other electrical appliances, turn on this one separately, if it is turned on normally, it means that it does not leak, if it will also trip, it means that the problem is on this equipment.

If there is no leakage equipment, it is a load problem, you can first see how big your air opening is (also pay attention to the allowable load of the meter), and then convert the total power of the electrical appliances you turn on in use, (refrigerator and air conditioner to compressor start whether the power is calculated), if it is indeed overload, it is impossible to adjust and avoid the problem of meter expansion and air replacement should be considered. If it is not the above problem, then change to a new empty open with the same capacity to see if it is caused by empty opening failure or allergies.

It may be a faulty contact in the socket, and the temperature of the socket will rise after a while, and the leakage will trip.

The socket trips as soon as it is used, first of all, look at whether the wiring in the socket is connected, whether there is a short circuit, in fact, it is very likely that the capacity of the socket is relatively small.

1. Check whether there is leakage.

2. Turn off the socket, and if the brake does not jump, it is the problem of the socket.

3. If the gate is still jumping, change to a new gate.

Summary. The reason why the socket power supply often trips: there are generally two situations, one is leakage tripping, and the other is overload tripping.

1. There should be many household appliances on the socket line at home, and part of the current load is generated during normal operation, and the current tolerance of the line itself is limited, and when the trip current limit is reached, there will be a trip situation. 2. If it usually does not jump and trips or is easy to trip when using an electrical appliance, it means that the electrical appliance has a leakage or a place with poor insulation. 3. 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.

4. 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.

My socket in my house has been 11 years this year, and now there is nothing, and it will trip by itself after a while, what is the reason for you?

It should be empty and small, overloaded, change an air switch to send electricity to use, after a while, trip, first of all, you can directly eliminate short circuit and leakage, why? Because a short circuit or leakage of a wire trips directly, not after a while. The second reason is:

Air opening leakage quality problems or aging, check whether the damage method, the leakage protector has a button to press once a month, after pressing can trip normally, it means that the air leakage leakage protection is no problem, if there is no response after pressing, it means that the leakage protector has been damaged. The third reason is wire overload, with an 80% and 90% chance of being due to overload. Generally speaking, if the wire is overloaded, it will overheat, and when the heat reaches a certain temperature, it will trip.

In the case of tripping, we can touch the leakage protector with the back of the hand, if you can feel the temperature, it is the tripping caused by overload, the fourth situation is due to the loose wire end of the empty leakage protection or the wire joint is not firm, resulting in virtual connection, and the virtual connection will produce overheating, causing the tripping of the leakage protector. The fifth situation is the aging of the wire, it will form a decrease in the insulation value between the wires and the wires, and a faint short circuit or leakage will be formed, this situation is not very obvious, it cannot be measured with a multimeter, we can use a megohmmeter to measure the insulation resistance between the wires, if it is greater than the megohm, there is no problem.

Fault Details:

1. When the neutral wire of the socket and the live wire are reversed, if the upper circuit is a leakage protector at this time, it will be automatically judged to be leakage protection and cause tripping when it is used. At this time, the power supply should be cut off immediately, and then the neutral wire and the live wire should be replaced back to the correct wiring, and if there is a burned line, it should also be replaced in time.

2. When there is a short circuit or leakage of the electrical appliances used, if the socket is used at this time, it will cause the leakage protector to break and trip. You should cut off the power and check the electrical appliances immediately, and of course you can contact the maintenance master in time.

3. The situation that the line load exceeds the rated power is because several electrical appliances used are high-power electrical appliances, and when used together, the rated power of the circuit will be exceeded, resulting in empty opening tripping. It is advisable to minimize the amount used when using electrical appliances.

4. The leakage phenomenon of the branch line is because the leakage current of 30 mA is not reached at this time, so the leakage protector will not trip, but after plugging in the electrical appliances, the current will become larger and trip immediately.

If the air switch trips, this situation is basically caused by excessive power consumption.

Check whether the leakage switch reset button is reset. Close normally after pressing the reset button. 2.

Check whether the leakage switch is wired correctly. If it is incorrect, it will need to be rewired. 3.

Check the line insulation on the load side of the leakage switch, if it is short-circuited and grounded, it needs to be troubleshot before it can be closed normally. 4.If it is an indoor power distribution room, turn off the lighting.

Dial the electrical equipment on the socket and send power to each circuit of the indoor distribution box one by one, and you can conclude that there is a fault along the way. Such as: short circuit, leakage, electrical burnout, grounding, etc.

In this case, it is very likely that the socket is in poor contact with the plug and overheating and the socket is tripping, and there is also a possibility that the socket is overloaded and the socket is overheated.

The socket trips after a while for the following reasons.

In the case of power failure, check whether the terminal of the socket is burned out, and secondly, measure whether the power supply voltage of the socket is normal? Measure whether there is a short circuit in the neutral live wire?

It is because the power of the appliance used exceeds the power experienced by the outlet.

The consumption rate of electrical appliances is too large, and the current is too large, resulting in overcurrent (overheating) protection action. Thus tripping.

The situation you are talking about is most likely caused by a short circuit on the socket or an excessive load on the socket. First of all, if you rule out overload or leakage, then it is a problem with the electric switch.

The switch hardware is generally fine, look at the parameter setting of 1000A air opening, 1000A is the shell current or the rated current, if it is the rated current, what is your long-delay setting current (IR)? Whether the IR current value is adjusted too low, or the IR time is too short, the parameter setting of general motor protection must avoid the motor starting current.

Check that there is no compression between the wire and the circuit breaker.
