Revision Standard - Active.
Metal-enclosed (ME) bus assemblies for indoor and outdoor use are discussed in this standard. The types of assemblies covered are nonsegregated-phase bus, cable bus, segregated-phase bus, and isolated-phase bus. Rated maximum voltages of ac ME bus assemblies range from 1058 V through 38 kV with continuous-current ratings of 600 A through 26 000 A for self-cooled ratings and up to 50 000 A for forced-cooled ratings. Rated maximum voltage levels of dc ME bus assemblies range from 300 V through 3200 V with continuous-current ratings of 600 A through 15 000 A. Service conditions, ratings, temperature limitations and classification of insulating materials, insulation (dielectric) withstand voltage requirements, test procedures, and application are discussed. A guide for calculating losses in isolated-phase bus is included.
