Red outer coating identifies which cable type?

Red outer coating identifies which cable type?

• A. Fire alarm circuit cable
• B. Data cable
• C. Power cable
• D. Grounding conductor

Answer: (A)

Colors on the outer jacket are used as quick labels to identify the type of circuit a cable carries. Red outer coating is widely used to identify fire alarm circuit cables, which are part of life-safety signaling. This visual cue helps installers and inspectors keep life-safety wiring distinct from data or power cables and ensures the right installation standards and testing apply. Data cables typically have jackets in neutral colors like gray or blue, power cables use other color schemes, and grounding conductors are green or bare. So the red jacket specifically points to a fire alarm circuit.
