Anschlusssysteme (connection systems) refer to various technologies used to link electrical power grids, plumbing pipes, or data and multimedia networks.

Elektrische Netzsysteme (Netzformen)

Electrical grid systems define how the protective ground and neutral conductors are configured in low-voltage power installations according to DIN VDE 0100:

1. TN-Systeme: The operational grounding is directly connected to the main ground; subclasses include TN-C (combined neutral and protective conductor) and TN-S (separate neutral and protective conductor). [1]
2. TT-System: The power source has a direct ground connection, and electrical equipment bodies have a separate, independent ground connection.
3. IT-System: An ungrounded (or impedance-grounded) power supply network used where high continuous availability or safety is required.

Rohr- und Sanitär-Anschlusssysteme

Water and heating pipelines are connected using different mechanical or thermal techniques:

1. Pressen: Fast and reliable connection using pressing tools and specialized fittings.
2. Löten / Schweißen: Thermal bonding for permanent, tight metallic or plastic joints.
3. Stecken / Schrauben: Removable or push-fit mechanical joints for quick installations.

Netzwerk- und Multimedia-Anschlüsse

Data and communication technology relies on standardized modular jacks and faceplates:

1. RJ45 / RJ12: Standard multi-pole sockets used for Ethernet data networks and traditional telephone lines.
2. Boden- und Zählerplatzsysteme: Floor boxes and meter panel assemblies designed for orderly cable routing and power distribution.
