Which NEC Article covers Instrumentation Tray Cable?

• A. NEC Article 725
• B. NEC Article 727
• C. NEC Article 760
• D. NEC Article 780

Answer: (B)

Instrumentation Tray Cable is the type of control and instrumentation wiring used in industrial settings mounted in cable trays for fixed installations. In the NEC, cables are organized by their application, and the article dedicated to this wiring type specifically addresses Instrumentation Tray Cable—its construction, ratings, and how it may be installed. That makes it the best fit when the specification calls for ITC, because the article defines what ITC is and lays out the exact rules for its use. Other articles cover different families of circuits—one focuses on power‑limited Class 2 and Class 3 circuits, another on fire alarm systems, and others cover different cable types—so they don’t apply to Instrumentation Tray Cable. When working with ITC, you refer to the article that explicitly names Instrumentation Tray Cable to understand the requirements for its conductors, insulation, jacket, and installation in cable trays.
