What is the primary purpose of color-coding wiring during inspection?

• A. It helps verify correct circuit identification and reduces miswiring.
• B. It provides decorative appeal.
• C. It marks manufacturing batch.
• D. It indicates wiring length.

Answer: (A)

Color-coding wiring during inspection is about quick, reliable circuit identification. Standardized colors let technicians know at a glance what a wire’s function or source is, so they can verify that the right wire is connected to the correct circuit, device, or power point. This makes it much easier to trace paths, confirm terminations, and catch mismatches before they cause faults, shorts, or damage. The other options aren’t the purpose: color is not used for decoration, batch marking, or indicating wiring length—those attributes are handled by separate labeling or documentation practices.
