Electrical Distribution Systems Electrical systems are mission critical to manufacturing operations. These systems include transformers, electrical switchgear, distribution panels and cable structures. Manufacturing operations often produce dust and dirt or corrosive agents that can accumulate on electrical connections and can cause damaging short circuits and arcing. Aging and under maintained systems can overload or short out. Breakdown of electrical systems can frequently mean the loss of income and customers. © 2004 The Hartford Steam Boiler Insurance and Inspection Company.     All rights reserved.
