samleledninger

Samleledninger is a Norwegian term used in electrical engineering to describe a set of conductors that gather currents from multiple circuits into a common line. The concept can apply to different structures, most often to trunk feeders or busbar arrangements in distribution systems. In many installations, samleledninger are realized as a dedicated conductor assembly or as a section of a main feeder that collects several branch circuits before feeding a switchgear, transformer, or distribution panel.

Construction and arrangement vary by use. They may consist of thick conductive bars (busbars) or insulated cables arranged in a cabinet, cable tray, or duct, with appropriate insulation, spacing, and protective enclosures to handle the expected currents and short-circuit conditions. Thermal management and protective devices are important, since aggregation raises current and heat.

Applications include power distribution in buildings, industrial facilities, and substations, where multiple feeders must be collected into a common supply path. In residential installations, terms like main feeder or trunk line might be used to describe the same function in a simplified way.

Safety and standards: installation should follow relevant electrical codes and standards, such as local regulations and international standards (for example IEC 60364 or national equivalents), with attention to current ratings, clear labeling, proper grounding, and overcurrent protection.

Etymology and translation: samlet means "to collect" in Norwegian, and samleledninger are the conductors that perform the collection. In English, terms such as busbars, trunk cables, or feeder conductors may be used depending on context.
