Maintenance issues:


Regular Inspections: Regularly inspect wires, cables, outlets, and circuit breakers to look for fraying, hot spots, and loose connections.

Clean the small power distribution unit: Clean the box regularly to prevent the accumulation of dust, corrosion or insulation materials.

Hot Spot Detection: Use an infrared thermal imaging camera to detect potential overheating issues and fix them promptly.





Follow safety regulations: Follow all electrical safety regulations and use appropriate personal protective equipment.

Emergency preparedness: Make sure you have a fire extinguisher and emergency power-off equipment.

Professional maintenance: Ask professional electricians to perform regular inspections and maintenance to ensure the safety and reliability of the system.


Proper installation and maintenance can reduce the risk of electrical accidents and ensure the normal operation of the power system. Always consult a professional electrical engineer if you have concerns or questions.
