One line at home always trips, refrigerator, computer, air conditioner, computer line. That small circuit breaker is C25. The residential property electrician said it was too small.

1. First, analyze the reasons. There are two cases of tripping, one is leakage and the other is overload.

2. Before, you said that the circuit breaker is C25, which is too small and wrong.

3. The meaning of air conditioning letters is:

C curve: the tripping current is (5~ 10)In, which is suitable for protecting distribution lines, lighting lines and motor circuits with large switching current;

D curve: the tripping current is (10~20)In, which is suitable for protecting equipment with large surge current, such as transformer solenoid valve;

Simply put, C is suitable for lighting circuits.

D is suitable for power supply circuit.

You should choose the power circuit breaker, because the surge current is relatively large when the electrical appliance is started.

5. The other 60 seems a little too big. This should be selected according to your electrical appliances. Generally, D32 is enough for home use.

220 volts, your power multiplied by 8 is ampere.

6. Finally, I suggest you check for short circuit and leakage.
