The reasons for the fire in the electric meter box are complex and diverse, mainly including the following aspects:

Electricity overload: When the capacity of the meter box is insufficient or high-power electrical appliances are used, or multiple electrical power sources are turned on at the same time, the equipment is prone to overload operation, causing overheating, short circuit, and ultimately leading to fire. Especially during peak electricity consumption periods such as summer, this phenomenon is more common.

Equipment aging: As the usage time of the meter box increases, components such as wires and electrical components may age due to long-term disrepair, resulting in poor operation, reduced insulation capacity, and causing problems such as short circuits, arcs, and electric sparks, ultimately leading to fires.

Improper installation and maintenance: The installation of the meter box does not comply with regulatory standards, or regular maintenance and testing are not carried out, which may also lead to safety hazards. For example, equipment with fire resistance was not used during installation, or aging, damage, and other issues were not detected and addressed in a timely manner during use.

Environmental factors: Dampness and rainwater infiltration may also cause damage to the electrical components inside the meter box, increasing the risk of short circuits and fires. In addition, some residents in residential buildings illegally pile up flammable materials such as debris and old furniture around the electricity meter box, which can also pose safety hazards.

In summary, in order to prevent the electric meter box from catching fire, it is necessary to regularly check the usage of the electric meter box to ensure that it is not overloaded, aging, installed in a standardized manner, and to maintain the cleanliness and safety of the surrounding environment. At the same time, when a fire is discovered, the power should be immediately cut off and appropriate firefighting measures should be taken.
