maadoitusmerkintä
Maadoitusmerkintä, known in English as the ground symbol or earth symbol, is a standardized icon used in electrical and electronic engineering to indicate a connection to ground or earth potential. This symbol is crucial for safety and proper functioning of electrical systems. It typically appears as a series of horizontal lines stacked vertically, with the lines decreasing in length from top to bottom, or as a diagonal line with perpendicular tick marks.
The purpose of a ground connection is to provide a safe path for electrical current to flow
The specific appearance and placement of the maadoitusmerkintä can vary slightly depending on international standards and
