jarðleiðari
A jarðleiðari, often translated as earth wire or ground wire, is a crucial component in electrical safety systems. Its primary function is to provide a low-resistance path for electrical current to flow to the earth in the event of a fault. This prevents dangerous voltages from accumulating on exposed metal parts of electrical equipment.
In most electrical installations, the jarðleiðari is colored green, green and yellow, or brown. It is connected
Without a properly installed jarðleiðari, a fault could leave the metal casing live, posing a severe risk
