Subpart S does not define “cable” or “cord.” However, the National Fire Protection Association (NFPA) which publishes a consensus standard, on which Subpart S is based, but which OSHA does not enforce, offers guidance on the meaning of these terms. Specifically, NFPA 79-2012(1) provides the following definitions: Flexible Cable – A cable or special cable manufactured with flexing or constant flexing properties. Cable – A combination of conductors insulated from one another with a common covering that is not a cord. Cord – Two or more flexible insulated conductors enclosed in a flexible covering that provides mechanical protection.
