What color is acceptable for high-voltage cables?

Explanation:
High-voltage cables are colored to signal a clear, serious hazard so workers know to use special precautions. Orange is the standard color used to designate high-voltage conductors, making it immediately recognizable as equipment that must be de-energized and handled with appropriate PPE and procedures. This consistent signaling helps prevent accidental contact with live HV circuits and reduces confusion with other wiring that serves different purposes. Green is generally reserved for grounding, while blue and red have their own typical uses in various systems, so sticking with orange for HV cables keeps hazard recognition unambiguous.
