Which topic is covered by neutral conductors in NEC?

• A. Phase conductor routing
• B. Neutral conductors
• C. Grounding electrode requirements
• D. Transformer impedance

Answer: (B)

Neutral conductors are the return path for current in electrical circuits. In NEC, the rules that apply to neutral conductors focus on how they carry the current back to the source, including proper sizing to handle the load and correct identification (such as color coding). This distinguishes them from topics that deal with routing hot (phase) conductors, requirements for the grounding electrode system, or transformer impedance. So the topic covered by neutral conductors is their role as the current-return path and the related sizing and identification requirements, not the other areas referenced by the other topics.
