Kopplingsbox

A kopplingsbox, often translated as a junction box or connection box, is an enclosure used in electrical installations to protect and provide access to electrical connections. Its primary function is to safely house wire splices, terminals, and other electrical components, preventing them from being exposed to the environment or physical damage. Kopplingsboxes are essential for ensuring the safety and integrity of electrical circuits.

These boxes come in a variety of shapes, sizes, and materials, depending on their intended application and the environmental conditions they will be exposed to. Common materials include plastic, metal (such as steel or aluminum), and sometimes specialized composites. The choice of material often depends on factors like fire resistance, corrosion resistance, and the need for electrical grounding.

Kopplingsboxes are designed to be easily accessible for maintenance, inspection, or modification of the electrical wiring. They typically feature knockouts or threaded entries for conduit or cable glands, allowing for a secure and protected entry of electrical cables. Internal components might include terminal blocks, wire nuts, or other splicing connectors. The lid or cover of the kopplingsbox is usually secured with screws or a snap-fit mechanism, providing a seal against dust, moisture, and other contaminants. Proper installation and sealing of a kopplingsbox are critical to prevent short circuits, electrical fires, and electric shock hazards.
