Electrical wiring practices and cable color codes in Saudi Arabia strictly conform to International Electrotechnical Commission (IEC) standards alongside local SASO regulations. For single-phase alternating current (AC) power systems, the live wire is colored brown, the neutral wire is blue, and the protective earth or ground wire utilizes a distinctive green-and-yellow combination. For three-phase AC power systems, the three individual phase conductors are designated as brown for L1, black for L2, and grey for L3, while maintaining the blue color for neutral and green-and-yellow for earth. Direct current (DC) and control circuits follow corresponding international harmonized guidelines to ensure absolute safety and uniformity.
