Which statement about multiple conductors under a single terminal is true?

• A. They must be capped with tape
• B. They must be labeled and marked
• C. They can be left unmarked
• D. They should be twisted together

Answer: (B)

When more than one conductor shares a single terminal, you must identify each wire so you can tell what it connects to and what function it serves. Labeling and marking the conductors keeps you from mixing up wires during testing, maintenance, or future work, which helps ensure the right circuit is tested or repaired and prevents cross-connections that could cause a fault or false alarm. In practice, you’d place durable markings or tags on each conductor at the terminal to show its destination or zone, so anyone servicing the system can follow the wiring accurately. Taping alone isn’t a reliable identification method, and leaving conductors unmarked invites confusion and mistakes. Twisting conductors together at a terminal is not appropriate—it creates an unstable connection and obscures which wire goes where, compromising safety and system performance.
