distributionstavler

Distributionstavlar, commonly translated as distribution boards or distribution panels, are electrical assemblies that receive power from a single source and distribute it to multiple outgoing circuits within a building or installation. They provide centralized protection, switching, and control for the circuits they feed, helping to organize wiring and improve safety and fault isolation.

A distributionstavle generally consists of an enclosure, one or more main protective devices, busbars or a busbar system to carry current, and a collection of circuit breakers or fuses. Additional components may include residual current devices (RCDs/RCBOs), a main disconnect, neutral and earth bars, meters, and labeling for each circuit. Many distributionstavlar are mounted on DIN rails and are designed to be modular, allowing easy addition or replacement of protective devices as circuits change or expand.

Types and configurations vary by application. In residential settings, a main distribution board typically serves as the central point for all household circuits. In commercial or industrial environments, sub-distribution boards are used to split power to different floors or areas. Some boards integrate metering or remote monitoring, and they can be designed for low-voltage systems with specific fault-current ratings and short-circuit withstand capabilities.

Standards and regional differences govern construction, labeling, and safety requirements. Common reference points include low-voltage switchgear and controlgear assemblies standards and electrical installation codes that specify enclosure rating, protection against electric shock, and proper insulation and grounding practices. Distributionstavlar must be installed and maintained by qualified personnel in accordance with local regulations.

Safety and maintenance are essential: never open an energized enclosure, and ensure that circuits are de-energized and properly locked out before work. Regular inspection of labeling, insulation, and protective devices helps maintain reliable operation.
