What is the reason for the trip of the electric box?

It may be the cause of overload. Whether empty or missing, it has overload protection function. Overload is easy to understand. If there are many electrical appliances in the line and the current generated is greater than the load of the circuit breaker, the switch will trigger overload protection and trip.

1, switch damage: After many people have electricity problems at home, the first thing that comes to mind is "something is broken", the electric kettle can't be broken, the rice cooker can't be broken, and the switch is broken. Although the service life of qualified circuit breakers can be as high as 10 years or longer, the switch may be damaged.

Check whether the switch is damaged: directly remove the load end of the trip switch and connect it to other circuits. If the switch still trips or cannot be pushed up, it proves that the switch has been disconnected.

Solution: Of course, the best solution to switch damage is to replace it directly. A reminder, before buying a new switch, it is recommended to remove the old switch, or take a photo for the merchant to replace it with an identical one, otherwise the merchant will not know what type of switch you want to buy.

2. Overload: No matter it is empty or leaking, it has overload protection function. Overload is easy to understand. If there are many electrical appliances in the line and the current generated is greater than the load of the circuit breaker, the switch will trigger overload protection and trip. In addition, there is another case where "overheating" triggers the tripping of overload protection, and the basis for judging the overload of circuit breakers is "calorific value". The greater the current, the greater the calorific value, but the resistance increases, and the virtual connection of wires and thin wires will also lead to an increase in calorific value.

Check whether the switch is overloaded: 1. The circuit breaker trips from time to time (or trips after closing for a period of time), and the reset button is not prominent after tripping; 2. Don't start the machine when it is overloaded, and start it normally when the electrical appliances are reduced.

Solution: 1 to reduce power consumption; 2. Re-tighten the loading port of the wharf; 3. Replace the circuit breaker with the correct model and current.
