Which color is orange for innerduct?

• A. Blue
• B. Red
• C. Orange
• D. Green

Answer: (C)

Color coding helps you quickly identify what kind of cables are housed in innerduct and keeps power and communication cables separate. Orange is the color commonly used to designate data/communications networks, including fiber optics, inside innerduct. That visual cue helps installers and technicians know the duct is intended for network cables rather than electrical power, reducing the chance of mixing types. Other colors may be used for different services or can vary by manufacturer, but orangeon innerduct is the standard hint for data/fiber content.
