[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, unique technical performance, fixed location, unique configuration functions, lack of site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. The numerous parameters displayed on distribution box data generally indicate that low-voltage circuits are constructed according to electrical wiring requirements, assembling switching equipment, measuring instruments, protective electrical devices, and auxiliary equipment in enclosed or semi-enclosed metal cabinets or panels to form a low-voltage distribution box. During normal operation, circuits can be connected or disconnected using manual or automatic switches.

[0003] In existing distribution boxes, multiple wires are connected to the residual current device (RCD) inside the box. When the connection between the RCD and the wires becomes loose, sparking can easily occur at the connection point, causing the wire insulation to break. When the detached wire core comes into contact with the distribution box, the box will become energized, posing a safety hazard. Utility Model Content
