This standard provides requirements for the design and installation of safety related electrical cable systems@ including associated circuits@ in nuclear power generating stations. Also provided are requirements for the design and installation of those nonsafety related cable systems that may affect the function of safety related systems. NOTE: The term associated circuits is not repeated throughout the text; however@ all requirements for the design and installation of cable systems for Class lE circuits shall apply equally to associated circuits unless it can be shown by test or analysis that the associated circuits cannot affect the performance of the Class lE circuits. Purpose The purpose of this standard is to identify existing standards and to establish requirements pertaining to safety related cable systems in nuclear power generating stations. Solutions are recommended for areas of concern such as fire protection@ raceways@ separation@ cable performance requirements@ and installation acceptance testing and documentation.1
