Correct answer to question 7015
- B: A grounded (neutral) conductor
Explanation
Section 404.2(C) generally requires a grounded conductor at switch locations controlling lighting loads in habitable rooms, bathrooms, hallways and stairways. The neutral allows occupancy sensors and electronic controls to be added later without rewiring.
