The kettle at home is leaking or short-circuited. It was found that the home leakage idle speed did not jump, and the main brake downstairs tripped. What happened?

First of all, the configuration size of the main brake is appropriate and within the normal working range.

Secondly, at least one of the home leakage protector and air switch is abnormal, which may be broken. You can check the air switch by checking its test button. In addition, these two may be configured too much, leading to action. More likely to be bad. It usually lasts for more than ten years.
