Distribution boxes are assigned an IP (Ingress Protection) rating, which indicates their resistance to dust and water. You rely on the safety protection function of a low voltage distribution box every day. The low-voltage power supply system at the construction site shall be equipped with a general distribution box, a distribution box and a switch box to implement three-level power distribution. When electrical problems occur—such as short circuits or excessive power draw—the circuit. It functions as the central hub that distributes electrical power from the main supply line to various branch circuits within residential, commercial, and industrial settings.

The proper installation of a distribution box involves placing it at the right height to ensure safety and convenience. (3) Power distribution from tertiary switch boxes to electrical equipment must follow the "one machine, one switch" principle, with no branching allowed. The placement and mounting height of this equipment are governed by stringent regulations, primarily outlined in the National Electrical Code (NEC).
