Abstract :
The 1971 edition of the National Electrical Code contains over 500 revisions of the rules in the previous (1968) edition. This paper is confined to a discussion of only those revisions which are of importance to electrical installations in industrial plants. New wiring methods which have been recognized are described along with new requirements for the protection of motors, transformers, services, electrical equipment in hazardous locations, and the installation of temporary wiring.
