When the inner shell leaks electricity due to aging of the circuit, a human body contacts with the box body, current is transmitted from the metal conductor to the resistor to the neon lamp to the human body to the ground to form a loop, and at the moment, the neon lamp emits light to remind people of the leakage of the inner shell.

The existing household electric box can automatically trip and disconnect a circuit when overload occurs during use, and the mode can protect the circuit, but direct tripping without early warning also affects the normal operation of other electric equipment, and after tripping, many electric equipment needs manual restarting by personnel, so that the use is inconvenient.
