Summary of inspection items for low-voltage distribution cabinets: 1. Check if all electrical component names and numbers on the distribution cabinet are clear and correct. 2. Check whether all operating handles, buttons, and button positions on the distribution cabinet match the actual situation, whether they are firmly fixed, and whether the operation is flexible. 3. Check if the instrument panel or dial glass of the power distribution cabinet is loose, and if the voltage and current indications operate normally. 4. Check if the on-off signal and other signal indications on the distribution cabinet are correct. The red light indicates that the switch is in the closed state, and the green light is in the disconnected position. 5. Check if the switches and fuses inside the distribution cabinet are secure and there is no overheating phenomenon. 6. Check if the wiring terminals and busbar connectors are tightened and if there are any precautions: 1.
