The main faults that may occur during the use of lighting electrical ready board boxes include:

Environmental temperature impact: The surrounding air temperature is too high or too low, exceeding the normal working range of the equipment. It is necessary to improve the electrical ready board box environment to ensure that the temperature is within the specified range (such as the upper limit not exceeding 40 ℃, the lower limit not lower than -5 ℃ or -25 ℃).

Electrical component failure: such as circuit breaker failure to close, contactor burnout, etc., may be caused by product quality issues or improper installation. Reliable quality products should be selected and reasonably set and installed.

Circuit problems: such as wire aging, overload, short circuit, etc., it is necessary to regularly check the condition of the wire to avoid overloading and ensure the safety of the circuit.

In summary, the fault analysis of lighting electrical ready board boxes needs to comprehensively consider multiple factors such as environment, equipment, and wiring.
