What is CIC Circuit Integrity Cable used for?

• A. It is standard wiring for general lighting circuits
• B. It is a shielded coax used for video signals
• C. It is fire-resistant wiring meant to keep functioning during a fire up to 2 hours
• D. It is a power cable for heavy machinery

Answer: (C)

Circuit Integrity Cable is fire-rated wiring designed to keep critical life-safety circuits operating during a fire. It resists high temperatures and maintains electrical continuity for a specified period, typically up to two hours, so systems like fire alarms and emergency communications can function when normal power may be compromised. This distinguishes it from ordinary wiring for lighting, shielded video coax, or heavy machinery power, none of which are built to preserve operation in fire conditions.
