Code Q&A

Q. Does the Code permit installation of nonmetallic-sheathed cable in a three-story hotel building?

A. Yes, as long as the structure is built of Type III, IV, or V construction and the cable is concealed within walls, floors, or ceilings that provide a thermal barrier of material with at least a 15-minute finish rating as identified in listings of fire-rated assemblies [334.10(3)].
