suojamaadoitusvärin

Suojamaadoitusväri refers to the specific color used for protective earth conductors in electrical installations. In many countries, this color is standardized to ensure easy identification and prevent accidental misconnection. The purpose of protective earthing is to provide a safety path for electrical current to flow to the ground in the event of a fault, thereby preventing electric shock. The distinctive color of the protective earth wire allows electricians and maintenance personnel to quickly and unambiguously distinguish it from live conductors and neutral conductors.

The most commonly used and internationally recognized color for protective earth conductors is green and yellow. This combination is specified in standards such as IEC 60446 (now largely superseded by IEC 60445). The green and yellow striped insulation serves as a universal visual cue for safety. In some older installations or specific regional variations, other colors might have been used, but the green and yellow scheme is the current prevailing standard for new installations and in situations where wiring is being modified or extended. Adherence to this color coding is crucial for electrical safety and compliance with regulations.
