Diagnose the fault in a low voltage distribution box by checking for overheating, loose connections, and using voltage testers for safe troubleshooting. Leakage fire: The so-called leakage of electricity means that the insulation ability of the wire or the bracket material decreases due to some reasons (natural or man-made reasons, such as wind and rain. Outdoor low-voltage power distribution boxes (hereinafter referred to as "distribution boxes") are low-voltage distribution equipment used in 380/220V power supply systems to receive and distribute electrical energy. If there is no leakage and the line is tightened, the neutral line burns badly, then the neutral line return current is too large! For example, on the same working circuit, when installing wires, several live wires will be pulled to various devices, while the neutral wire only shares one.
