The power distribution box itself will not cause an electrical fire as long as no illegal operations are carried out.
Power distribution boxes generally provide low-voltage power (such as 380V three-phase power, 220V single-phase power), and the spacing between the internal copper bus bars should be conforms to national standards and circuits. Circuit breakers and other switches must be configured. The equipment has a protective function. Additionally, the exterior of the electrical distribution box must be insulated and protected by the chassis. Therefore, as long as the enclosure door or insulation board is not opened. illegal operations are carried out, there will be no electric shock accidents, let alone ignition accidents such as arcing.
