Why does the meter box make abnormal noise?

Abnormal noises in the meter box may be caused by a variety of reasons. One possibility is that excessive current due to poor circuit connections or faulty electrical equipment produces arcs or sparks, causing the noise. Another possibility is that the meter box itself is loose or damaged, causing abnormal sounds when components rub or vibrate. In addition, environmental factors such as temperature changes, moisture, etc. may also cause the components of the meter box to expand or contract, causing friction noise. Others may include aging of the electrical equipment inside the meter box, entry of foreign matter, etc. No matter what the cause of the abnormal noise is, it needs to be checked and dealt with in time to ensure the normal operation and safety of the meter box. If abnormal noise is found in the meter box, it is recommended to contact professionals for inspection and maintenance in time to avoid possible safety hazards.
