IEEE 628-2001

This standard contains the requirements for the design, installation and qualification of raceway systems for Class 1E circuits external to electric equipment and components for nuclear pwoer generating stations. Since aging and radiation have no known detrimental effects upon metallic raceway systems, and since non-metallic raceway systems are limited to underground or embedded applications, these two environmental conditions are not considered in this document. The embedments or structural members to which a support is attached are beyond the scope of this document.
