Enclosed bus-bar electrical distribution systems for industrial plants

Enclosed bus-bar distribution systems have come into common usage to meet the needs of industry for the greater availability of electrical power in production areas. Beginning in 1927 the automotive industry pioneered the application of enclosed bus-bar systems as a solution to the frequent recurring problem of modifying the electrical distribution system incidental to mass production changes. Since that time there has been an increased utilization of bus-bar systems by all branches of industry.
