The switch tripped, and the socket was connected at home, and the live wire tripped, what happened?

Judging by your description:

1. If the socket is connected to the live wire, the reason may be: there is a short circuit inside the socket or the line in the wall is broken, and the line is broken due to the activity during wiring.

2. The three wires of the general socket: respectively: a live wire, a neutral wire and a grounding protection wire, if the live wire and the grounding protection wire constitute an electrical circuit or the neutral wire and the grounding protection wire are mixed, the switch also trips.

3. Electricity safety is very important, and improper handling will be life-threatening; Therefore, if you don't know electrical technology, you can find an electrician to help you deal with it.

Tripping at home, inspection found that there is leakage between the live wire and the ground wire, the live wire on the air switch and the neutral wire are reversed, the fault disappears, but it trips after a period of time, and can be used normally after closing the power, but it is always repeated like this, how to check, please ask experts to help how to solve it.

1: As long as the live line trips, what's going on?

Answer: This wire connected to the live wire is leaking. (It may be that the line breaks and the skin collides with the wall).

2. I tested it with an electric pen, and the three wires connected to the socket have no electricity?

Answer: As soon as the line of fire was connected, it tripped. Definitely out of power.

The outer skin of the thread buried in the wall may have broken, causing the three threads to mix. Can only be pulled out to check.

The wiring should be colored, and the strong inner wire must be threaded through the pipe into the box, so that it will not be wrong, and use the table to see if the insulation of the wire is damaged.

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.

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.

If the household socket trips, usually, there are three aspects, the first aspect is the fault of leakage, the second aspect, if it is said to be plugged in and tripped, then it is because of the damage to your electrical appliances The third aspect is that the electrical appliances are too large and cause the socket to trip. It is recommended that you check whether the electrical appliances in your home are overloaded.

The empty opening of the socket is always tripped, because the electrical appliances on the socket or the socket itself have leakage. Check:

1. Unplug all the electrical appliances on the socket, close the air open, if the air can be closed, it means that a certain electrical appliance is leaking. Plug in the electrical appliances one by one, and find that a certain electrical appliance is empty and tripped, indicating that the electrical appliance is leaking.

2. After unplugging all electrical appliances, it still can't be closed and opened, which means that there is a problem with a certain socket. If there is a ground plug at home, it should be checked emphatically, because the floor is often mopped, and it is easy for moisture to enter the ground plug, and the floor plug has a high possibility of leakage.

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. The method of selecting the circuit breaker of the socket branch is that 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. Leakage of the socket branch: If the wire of the socket branch has leakage, because the leakage current of 30 mA is not reached, the leakage protector does not trip, but after plugging in the electrical appliance, the current will trip immediately.

Generally, there are two situations: 1. Leakage tripping; When using an electrical appliance, it does not trip at the beginning, and it trips after a while, indicating that the thermal stability of the electrical appliance deteriorates and leakage occurs, causing the socket to trip. 2. Load tripping; If more current is used on the socket line, it will trip to protect the circuit.

The first thing to see if there is leakage? Overload phenomenon, it is recommended to unplug all the external power supply and electrical equipment, and then close to test it, if there is no tripping situation, that is your own external line problem, this suggestion to see if there is any leakage of all the socket socket electrical appliances? However, I would like to emphasize here that it is best to find a professional to help, from the point of view of safety and quality, it is absolutely important.

Dear, there are several situations in which your inquiry leakage tripped:

1. Socket leakage, the gate has a self-protection function, and if leakage occurs, it will automatically trip! It is recommended to replace the socket!

2. Your socket plug is two, not three, there is no ground wire, leakage tripping is a protection function, it is recommended to replace the socket.

Air switch tripping is generally a load short circuit, and the load current exceeds the rated current of the empty open for a long time. The former finds the short-circuit point, and the latter increases the rated current value of the empty opening under the premise that the cross-sectional area of the conductor allows.

Leakage protector tripping is when the load leakage current exceeds 30mA, short circuit, and the load current exceeds the rated current for a long time. The former finds out the causes of leakage and short circuit, and the latter increases the rated current value of the leakage protector under the premise that the cross-sectional area of the wire allows.

There should be some household leaks, which are caused by it, ask an electrician to check it.

Focus on checking the power cord and load of the outlet, if not'Leakage, or overload, if the load is very small, it is basically caused by leakage!

Dear, hello, the tripping treatment method of the socket at home is as follows: 1. Turn off all the switches, and pull out all the electrical plugs, including the basement and other places that you don't pay attention to; 2. Close the main switch to test whether the main circuit is intact, if it is no longer tripped, it means that the main circuit is intact. If it trips, it proves that the problem is in the main circuit, and it is necessary to further disassemble the line partition wide regret domain to find, it is recommended to find a professional electrician.

3. After the main circuit is powered, the power is transmitted one by one, and the interval between each switch is half a minute. After the switch is sent, plug the electrical cords into the wall socket one by one, and each plug is plugged in half a minute apart. If a trip occurs when a switch is closed or an appliance is plugged in, the leakage point has been found.
