My friend s air switch tripped, why did the main air switch at home trip?

There are two reasons for the tripping of the switch circuit breaker, one is overload, the other is a short circuit, the overload is that the power is greater than the capacity of the switch itself, it will trip after a long time, and the switch with a larger capacity needs to be replaced at this time, the short circuit is the phenomenon that the zero line and the live wire are in direct contact with the household appliances or the line, and the fault of the short circuit is that as long as the electrical appliances are opened, the switch will trip, I have read your description, I preliminarily determined that there is a contact short circuit somewhere in the line, The contact short circuit phenomenon is that there is contact but sometimes the contact can not be returned, so the switch you use sometimes jumps back and sometimes does not jump, when it is turned on for the first time, it will jump, and the second time it will not jump back, it is a short circuit when you open it once, and the contact point is arced by the current at the same time as the switch trips, so when you turn on the second time, the arcing point will not contact the energized, so it will not trip, the above is the analysis of your description, for reference only, the actual situation also needs to be checked by an electrician.

Try to put the incoming wire on 40 amps, put the socket on 32 amps, generally speaking, the rated current of the incoming circuit breaker should be the largest, and the others are selected according to the size of the loop current, as for why the first time to pick the second time not to jump should not be a short circuit or leakage, if it is a short circuit or leakage the second time should also jump, it may be that the size of the circuit breaker is wrong or the circuit breaker is broken, try another one.

The air switch was changed. Something is wrong with the load module.

There are basically three situations when the air switch trips, the first is short circuit, the second is leakage, and the third is overload.

You can turn off the sub-switches first, and then you should be able to push the main switch (you can't push it is basically the main switch is broken), and then the sub-switches are closed one by one, and the main switch trips when you close the sub-switch, so you can know which route there is a problem, and then check the electrical appliances on this switch, or unplug some electrical plugs to see if there is a problem. This kind of problem is generally caused by sockets or lights, or it is caused by household appliances.

If your air switch is protected from leakage, then it may be caused by leakage in the electrical shell.

If your air switch is tripped for a period of time, then the possibility of overload is very large, first touch the shell, whether you feel the heat, and then you can turn on a few less appliances to see if it will trip, the best way is to use a current clamp to measure the current of the load connected to the air switch, if the actual current is greater than the rated value of the air switch, then it must be overload tripping.

It is estimated that the insulation of some old electrical equipment is greatly reduced, and there are many leakage tripping phenomena. For example, more than 10 years old washing machines, old refrigerators, and so on, ......

It is possible that this phenomenon of blindness isBecause of the leakage or short circuit phenomenon in the wiring at home, Zichun is pure, because the current air switches have these protection functions.

1. The current switches at home have the function of leakage protection, and when there is leakage, they will tripAt this time, it may be because there is a problem with the electrical appliances at home, you can unplug the electrical appliances from the plug and try it. 2. There is also the phenomenon of short circuit due to aging of the wiring at home, which needs to have a certain circuit foundation to be solved.

If you have no way to analyze the problem, you still have to ask a professional electrician to test and repair, which is safer!

There are several reasons why an air switch in your home trips:

1.Overload: When the number of electric orange pacemakers used at home is too large or the power of some electrical appliances is too large, it will cause the circuit to be overloaded, and the air switch will automatically trip in order to protect the circuit.

2.Short circuit: When the wire of an electrical appliance in the home is short-circuited, it will cause a short circuit in the circuit, and the air switch will automatically trip in order to protect the circuit.

3.Floor leakage: Floor leakage refers to the leakage of electrical appliances in the home, causing the current to flow to the ground, which will trigger the air switch to trip automatically.

4.Failure of the air switch itself: A failure of the air switch itself can also cause tripping.

If you are not sure about the specific reason, it is recommended to find a professional Yuanxiang electrician to check and repair. At the same time, in daily life, we should pay attention to the safety of electrical appliances, do not overload electrical appliances, and repair and replace old electrical appliances in time to ensure family safety.

The air switch trips to protect against dangers such as leakage and overcurrent. Tripped, carefully check the electrical facilities. It is the importance of life safety.

Hello, when there is a short circuit in the electrical equipment or wiring at home, the switch will trip.

1.Because household appliances are heavily loaded, exceeding the rated load 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 open the electrical appliances, when opening a certain electrical appliance tripping, you must first check whether there is a suspicion of leakage, or high-power electrical appliances, the load has accumulated to exceed the rated load.

3.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.

4.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.

5.Finally, if none of the above problems are the above, then change to a new empty open with the same capacity to see if it is caused by empty opening failure or allergies.

There are two reasons for the load at home to cause tripping, the first side is missing return, overload, and overload is an important reason for tripping! The second thing is leakage, when our load leaks, it will cause tripping!

It shows that the arrangement of the cloth sedan car in the home socks electrical wiring is not scientific and reasonable. For example, there is a phenomenon of poor insulation aging between the wires and the equipment being used in the home, or the mismatch between the electrical load and the operating current allowed by the excitation ......of the air and liquid sail can cause trouble when used
