suojamaadoitusjohtoa
Suojamaadoitusjohto, often referred to as a protective earth conductor or grounding wire, is a fundamental component of electrical safety systems. Its primary function is to connect exposed conductive parts of electrical equipment to the earth. This connection provides a low-resistance path for fault current to flow to the ground in the event of a fault, such as a live wire touching the metal casing of an appliance. Without a suojamaadoitusjohto, this fault current would instead flow through a person who touches the appliance, leading to a potentially fatal electric shock.
The suojamaadoitusjohto is typically colored green and yellow in many regions, a standardized color code to
