IEC Wiring Color Code Standards
These standards specify particular colors for wires to identify electrical conductors in both AC (Alternating Current)
The mandatory colors for power wiring in the National Electrical Code (NEC) are Green, Bare, or Green/Yellow (a yellow stripe or band on green) for the protective ground (PG), and White (or alternatively Gray) for the neutral wire. Many countries, including the UK (BS-7671), China, Russia, Hong Kong, Singapore, Ukraine, Belarus, Kazakhstan, Turkey, Israel, South Africa, Argentina, Malaysia, Saudi Arabia (KSA), and the UAE, have adopted the IEC wiring color codes. We will also examine the wiring color codes used in other. olor-coding. All circuits, raceways, and conduits shall be color-coded, labeled, and sized to match the appropriate t Colo er drawings. If the conduit size is not given on t...
