Installationsjordledningar, often referred to as grounding conductors or earthing conductors, are essential components in electrical installations. Their primary purpose is to ensure safety by providing a low-resistance path for fault currents to flow to the earth. This prevents dangerous voltages from appearing on conductive parts of electrical equipment, such as metal casings, which could otherwise pose a shock hazard to users.

These conductors are typically colored green and yellow for easy identification and are connected to the protective earth terminal in the electrical panel. From there, they run to all points of the installation where electrical equipment is connected. In the event of an insulation fault, where a live conductor accidentally touches a metal part, the installationsjordledning allows a large current to flow. This high current will quickly trip a protective device, such as a circuit breaker or fuse, disconnecting the power supply and mitigating the risk of electric shock.

The size of the installationsjordledning is determined by the rating of the overcurrent protection device protecting the circuit. It is crucial that the grounding system is continuous and properly connected throughout the installation to be effective. Regular inspection and testing of installationsjordledningar are recommended to ensure their integrity and the overall safety of the electrical system. Without a properly functioning installationsjordledning, electrical installations would be significantly more dangerous.
