Maadoituslanka

Maadoituslanka, also known as ground wire or earth wire, is a crucial component in electrical safety systems. Its primary function is to provide a low-resistance path for electricity to flow to the ground in the event of a fault or short circuit. This prevents dangerous voltages from accumulating on metal components of electrical equipment, which could otherwise pose a serious shock hazard to users.

In typical wiring systems, the maadoituslanka is connected to the grounding terminal of electrical outlets and directly to the metal chassis of appliances and other electrical devices. This wire is usually green or green and yellow in color, although its color coding can vary by region. When a fault occurs, such as a live wire touching the metal casing of a washing machine, the maadoituslanka immediately directs the excess current away from the appliance and into the earth.

This flow of current to the ground typically triggers a circuit breaker or blows a fuse, disconnecting the power supply to the faulty circuit. Without a properly installed and functional maadoituslanka, any electrical fault could result in the metal parts of an appliance becoming live, creating a severe risk of electric shock. Therefore, ensuring the integrity and correct installation of maadoituslanka is paramount for electrical safety in homes and workplaces.
