What are the common causes of small power distribution unit failures?

Common causes of small power distribution unit failures include:

Power supply problems: Unstable power supply, too high or too low voltage may cause the failure of the small power distribution unit.

Wiring problems: Problems such as poor contact, short circuit or open circuit may lead to poor current transmission and affect the normal operation of the meter.

Environmental factors: Environmental factors such as high temperature, moisture, corrosion, etc. may cause damage to the exterior and interior of the small power distribution unit.

Lightning strike: Strong lightning may produce overvoltage on the small power distribution unit, causing meter failure.

Illegal operation: Illegal wiring, disassembly or unauthorized modification of the small power distribution unit may cause it to be damaged or unable to function properly.

Equipment aging: The internal components of the small power distribution unit may age over time, affecting its performance and stability.

Regular maintenance and inspection, and rational use of the small power distribution unit can effectively reduce the probability of failure and ensure the normal operation of the meter. If problems are found, they should be repaired or replaced by professionals in time.
