It is widely recognized that arcing faults in switchboards contain large amounts of power and can create significant damage including melting switchboards, destroying substations, disabling ships, and causing human fatalities. While arcing faults occur with a fairly high frequency, electricity is so ubiquitous in our lives that most engineers are not personally associated with a major arcing fault. The navy has invested twenty five years investigating the causes, behavior, and prevention of arcing failures in low and medium voltage switchboards. Laboratory testing used to help understand the behavior of arcs in switchboards is presented. That data is then used to analyze actual switchboard arcing events and thus to determine the root causes of the events. Additional testing used to confirm the cause of each event is discussed.
