Use Your Metal

摘要

The failure of a service-entrance bus duct supplying power to a major grocery store data center and corporate facility created a dilemma for store management. Since this facility is the 24-hour support system for all store transactions, maintaining power to the data center and the corporate complex is critical for continued business operation. The long delivery time for a 4,000-ampere replacement bus duct prompted immediate repair by the installation of parallel conductors in a metal wireway, not in a bus duct.
