The air switch in the corridor has been tripping. What should I do?

The main switch in the corridor is usually an air switch, and the size of the air switch is determined by the national electrical standard. In other words, we can't change the size of this air switch. Because it is consistent with the cable in the upper area. Because the switch configuration in the household distribution box is only determined according to the household electricity load, the size of the air switch in the corridor is not considered. Finally, it can be seen that the size of the switches in the household distribution box is greater than the total number of air switches in the corridor. This phenomenon appears in the decoration process of many decoration companies. So we use high-power appliances, the switch in the household distribution box will not trip, the salary will trip, and the air switch in the corridor will jump.

When this happens, we should observe the overall size of the air switch in the corridor. For example, the corridor main air switch 40A, our household electrical load can not exceed 8800W at most. We can reasonably arrange the use of household appliances according to this electricity load. When you say corridor, you mean the stairs or the middle passage up and down your house, right? As I am at home, I know whether I will trip or jump when using high-power household appliances for no reason. The open working principle is to act as the protected electrical equipment first. Once the heavy current is overloaded, it will jump. When I was making a circuit board, the 220V filter capacitor exploded and became empty. Because it's a joke. Jumping is normal.

When the total power in air combat does not exceed the positive turbulent force in air combat, the leakage problem is eliminated and random jump occurs. This problem may fail at the miss distance, and the spring or clamp may fail. Sometimes it takes several times to make a button. The spring inside will make the bullet roll back and forth. Once stuck, it will only be elastic and have no sense of editing. I will walk back and forth several times. If you can't correct it, you can only change something else.

If there is leakage, it can be seen that the leakage is caused by tripping. For example, the line from the main switch to each branch switch in the corridor leaks electricity, or some furniture leaks electricity, but his room has no leakage and is directly exposed to the main leakage insurance place. In another case, the indoor leakage risk is 30 mA, and the general specifications of the total leakage risk are relatively large. For example, in the case of 50 mA, there are three indoor leakage places, and the average leakage current is only 20 mA, so the total leakage current adds up to more than 50 mA, and the total leakage insurance trips, and the indoor leakage insurance fails to meet the tripping standard. Someone stole electricity from the line, the uncontrolled current was large, and the air switch was overloaded and tripped. This is a common phenomenon of public power. I handled two cases of real estate theft in just three months. Cut off the current of the induction wire with caliper gauge, find the branch with considerable current, narrow the suspicious range, and then check the abnormal outside line.
