Electrical Panel Electrical Panels are an integral element of a hospital's electrical distribution system. The frequent cycling on and off of electrical loads creates heating and cooling which can loosen connections in electrical panels and cause electrical arcing (or short circuits). Arcing can damage not just electrical equipment but also result in surges and electrical disturbances that can damage other expensive equipment on premises. Because of the critical function of electrical systems in a hospital and the presence of fragile electronic diagnostic and imaging equipment, hospitals should have an Electrical Preventive Maintenance (EPM) program that includes regular infrared scanning. © 2004 The Hartford Steam Boiler Insurance and Inspection Company.     All rights reserved.
