The latest edition (Edition 7.0) introduced several important changes:
Note: In the latest 2021 edition, the provisions concerning the exact colors designated for specific conductors were elevated from mere recommendations to mandatory requirements. 3. Key Updates in IEC 60445:2021
| Conductor Type | Mandatory Color | Applicable Exception | | :--- | :--- | :--- | | | Green-and-Yellow | None. This dual-color combination is exclusively reserved for safety grounding. | | Neutral (N) | Light Blue | In cases where the cable has more than 5 conductors, numbering may be used, but ends must be marked blue. | | AC Phases (L1, L2, L3) | Brown, Black, Grey | Note: The standard provides these colors but does not rigidly assign which phase gets which color (this is often handled by specific regional harmonization documents). |
