IEC 61439-3:2024 Low-voltage switchgear and controlgear assemblies - Part 3: Distribution boards intended to be operated by ordinary persons (DBO) IEC 61439-3:2024 defines the specific requirements for distribution boards intended to be operated by ordinary persons (abbreviated DBO. The guide lists the process of design, assembly and documentation of a low-voltage switchgear assembly in the order of the necessary steps and at the same time assigns to these steps the relevant sections from the standard IEC 61439 / EN 61439. This section concentrates upon commonly used power distribution equipment: Panelboards, Switchboards, Low-Voltage Motor Control. Consequently, this series of standards has often been criticized and considered as difficult to understand and implement. The hub distributes electrical power from a single input source to various circuits throughout a building. It stipulates requirements for enclosure materials, installation dimensions, the mandatory "one equipment, one switch, one RCD" rule, mechanical structure, earthing systems.
