In an EV, what method is used to distinguish high-voltage cables from other wiring?

• A. Labeling with numbers
• B. Magnetic stripes
• C. Insulation type
• D. Color coding

Answer: (D)

Visual cues are used to flag high-voltage cables for quick recognition and safety. Color coding, with bright orange insulation, clearly signals that those wires carry high voltage and should be treated with extra precautions. This at-a-glance indicator helps technicians and first responders know to follow proper safety procedures, such as lockout/tagout and using appropriate PPE. Labeling with numbers can identify cables but requires looking up what each code means, so it’s not as immediate a signal as color. Magnetic stripes aren’t a standard method for indicating high voltage, and while insulation type can vary, it doesn’t provide the universal, instantly recognizable cue that color coding does. That universal color standard makes it the most reliable way to distinguish high-voltage cabling across EV models.
