Guidance is provided on the specification and selection of electrical power, control, instrumentation, and special-purpose cable, as typically used in nuclear facilities. This guide is not intended to be a design document, although many of the problems associated with the specification and selection of cable for nuclear facility applications can be avoided by the use of this guide. It is recognized that there may be other types of cable used in nuclear facilities. This guide should not be interpreted as precluding the use of such cables.
