Riser cable is suitable for running in which locations, with a fire coating meeting building codes?

• A. Riser cable is suitable for running in air ducts and spaces between the floor and ceiling with a fire coating that must comply with building codes
• B. Riser cable is used only for outdoor installations
• C. Riser cable is a type of coaxial cable
• D. Riser cable is obsolete

Answer: (A)

Riser cable is designed for vertical runs inside a building—through risers, shafts, and the spaces between floors. A fire-resistant coating or jacket that meets building codes is required so that, in a fire, the cable resists ignition and helps limit flame and smoke traveling upward along the vertical path. This is why describing its use in vertical interior spaces with a code-compliant fire coating best captures what riser cable is for. It isn’t about outdoor installations, it isn’t a specific coaxial cable type, and it isn’t obsolete.
