Red outer coating identifies which cable type?

Red outer coating identifies which cable type?

• A. It identifies fire alarm circuit cable
• B. It identifies power conductors
• C. It identifies shielded cable
• D. It identifies grounding conductors

Answer: (A)

Color coding in limited-energy cabling helps you quickly identify the function of a cable. A red outer jacket is used to identify fire alarm circuit cables, which carry life-safety signaling for devices like smoke detectors, pull stations, and notification appliances. This helps distinguish them from power conductors (which are typically black or another color used for mains), shielded cables (which show shielding in addition to jacket color), and grounding conductors (which are green or bare). So the red coating signals that this cable is part of the fire alarm system and must meet the related standards and routing requirements.
