The Impact of IEEE Standard 404 Revisions on Industrial Cable Distribution Systems

Prior to the 1986 revision of IEEE Standard 404, the design proof testing for extruded solid dielectric cables specified in AEIC Standard CS5-82 required testing and test levels that went beyond the scope of IEEE Standards 404 and 48, the joint and termination standards, respectively. As a result, it is perceived that cable accessory performance can be inferior to that of the cable. IEEE 404-1986 is a major step towards matching joint design proof testing with that specified for cable. The effects of the revised standard on cable joint performance and design, expected future industry activities on coordinating cable and accessory standards for consistent performance levels, and the benefits to industrial cable distribution systems are discussed.
