Anschlussdose

Anschlussdose is a protective enclosure used to house electrical connections and to terminate and distribute electrical cables within buildings. It provides a safe, accessible point for splices, connections to switches, sockets, or lighting fixtures, and ensures strain relief for conductors. They are used in concealed installations behind walls or ceilings as well as in surface-mounted installations.

Dosen come in various forms. Runddosen and Eckdosen are used in radial wiring; Unterputz-Dosen are set into the wall, while Aufputz-Dosen are mounted on the surface and covered by a lid. In drywall constructions, gypsum board boxes (Gipskarton-Dose) are used. They are typically made of plastic (PVC) or metal and have knockouts for cable entries and clamps or terminals to secure conductors.

They must offer sufficient space for the planned cable cross-sections, connectors, and device terminals, and they provide proper strain relief. The cover or lid must be securely fixable and remain accessible after finishing work. Dosen are designed to comply with relevant standards from VDE/DIN and must be suitable for the installation conditions, including moisture and fire safety in some contexts.

Safety and installation: a grounded or metallic box requires proper earthing; installation should follow local regulations and be carried out by qualified personnel. Dosen should not be used as a permanent concealment for inaccessible splices; only serviceable and accessible connections are allowed.
