How are high-voltage cables identified in an electric vehicle?

• A. Color coding
• B. Color shading
• C. Labeling with numbers
• D. Metallic coating

Answer: (A)

Visual identification of high-voltage cables in an electric vehicle is done with color coding. The insulation on these cables is typically orange, a bright, distinct color that signals danger and distinguishes HV wiring from the low-voltage system. This standardized cue lets technicians, emergency responders, and even bystanders recognize high-voltage components at a glance, promoting safer handling, proper PPE use, and appropriate de-energizing procedures. Relying on color alone is more reliable than shading, which can be affected by lighting or wear, and it’s more informative than labeling with numbers, which may not convey the hazard level. Metallic coating wouldn’t indicate voltage and could hinder quick recognition.
