Identification of insulated and bare conductors by colours

This document establishes a comprehensive framework for the identification of insulation colors and marking of bare conductors used within electrical systems. It provides detailed specifications regarding the color codes applied to wires and cables to ensure consistent visual communication across various applications. The guidelines cover the standardization of colors for live conductors, neutral lines, and protective earth circuits, aiming to enhance safety by reducing the risk of misidentification during installation and maintenance. By defining specific hues and their associated electrical functions, this specification facilitates uniform practices in the design and execution of low-voltage and medium-voltage wiring installations. The approach ensures that technicians and engineers can reliably interpret the visual signals presented by different wiring configurations, thereby promoting operational safety and efficiency in electrical projects. It addresses the requirements for marking and labeling to maintain clarity and prevent errors in complex electrical networks.
