Household distribution box trip:

1. Check the air switch control for damage. The power distribution cabinet distributes the electric energy of a circuit of the upper power distribution equipment to the nearest load. This equipment shall provide protection, monitoring and control of the load. According to the electrical wiring, the switchgear, measuring instruments, protective electrical appliances and auxiliary equipment are required to be assembled in closed or semi enclosed metal cabinet or on the screen to form a low-voltage distribution box. In normal operation, the circuit can be connected or disconnected by manual or automatic switch. Switch cabinet is an electrical equipment. The external line of the switch cabinet enters the main control switch in the cabinet first, and then enters the sub control switch. Each branch circuit is set according to its needs. For example, instruments, automatic control, motor, magnetic switch, various AC contactors, etc., some of them are equipped with high-voltage room and low-voltage room switch cabinet, with high-voltage bus, such as power plant, and some are also equipped with low cycle load shedding to ensure the main equipment.

2. Check whether the air switch wiring is correct. Incorrect, should be reconnected.

3. Check the insulation of the line at the load side of the air switch. If there is no short-circuit grounding, we need to eliminate the system fault before the normal closing can be realized.

In case of power transmission trip of household distribution box, it indicates that the line is short circuited to ground.

1. A button on the leakage protector will pop up after starting, and it can be closed by pressing it again.

2. It is a place with electric leakage, and its investigation. At the same time, there are also many with air leakage protection switch, you see where the power and short circuit.

3. The leakage protector is broken. My family is also a problem, that is, we are like this. All the sockets at home are divided into two leakage protectors, but as a country, students often trip. Later, I connected all the lines of this to another switch, and never skipped it. And the bad, even if they do not form a current to pass through, will also inexplicably trip for a period of time.

4. Select the standard distribution box to the right.
