What do WHITE wires signify?

What do WHITE wires signify?

• A. DC grounded conductor
• B. AC grounded conductor
• C. equipment grounding conductor
• D. externally powered conductor

Answer: (B)

In AC wiring, white is used for the neutral conductor, which is a grounded conductor. It provides the return path for current and is bonded to earth ground at the service panel to establish a reference and aid fault clearing. That’s why white wires signify an AC grounded conductor. The equipment grounding conductor is green or bare and is a separate safety path, while DC systems don’t typically use white for a neutral in the same way.
