Based on the NEC color-coding requirements, ground conductors must be designated by _____ and neutral conductors by _____.

Based on the NEC color-coding requirements, ground conductors must be designated by _____ and neutral conductors by _____.

• A. green, white
• B. green, black
• C. green, red
• D. green, blue

Answer: (A)

Ground conductors are identified with green to indicate the protective earth path, making it easy to recognize the grounding connection and keep it separate from live conductors. Neutral conductors are identified with white (or gray), which distinguishes them from hot conductors that use colors like black, red, or blue. This color coding helps ensure safe wiring and troubleshooting by clearly showing which wire is the return path for current and which is the safety ground. So the standard pairing is green for ground and white for neutral. Using other colors for neutral would confuse the system and could lead to dangerous mix-ups with hot conductors.
