When a grounded conductor is connected to a terminal, the identifying color must be which of the following?

• A. White or Silver
• B. Black
• C. Green
• D. Red

Answer: (A)

In electrical wiring, colors tell you what each conductor is for. The grounded conductor, which is the neutral path, is identified by white or gray insulation. This coloring differentiates it from hot (live) conductors, which are typically black or red, and from the equipment grounding conductor, which is green (or green with a yellow stripe). Using white or gray for the grounded conductor helps ensure you’re returning current through the neutral and not accidentally touching a live or grounding conductor. So when a grounded conductor is connected to a terminal, the identifying color should be white or gray (often described as silver in some contexts).
