Abstract
Although fires caused by heat generation due to Cu<sub>2</sub>O breeding in wire connections are well-known among fire investigators, there are few papers on the analysis and introduction of fire cases by heat generation due to Cu<sub>2</sub>O breeding. This study analyzed fire statistics caused by heat generation in electrical connections and the phenomena and features of heat generation due to Cu<sub>2</sub>O breeding. Then, a fire which occurred in the wire connection in a university lab by heat generation due to Cu<sub>2</sub>O breeding was analyzed in more detail. This fire case could reach a conclusion that heat generation due to Cu<sub>2</sub>O breeding caused a fire in the wire connection through the fire pattern investigation of fire origin, the visual investigation of wire connection, 3D CT, power-on-test, and stereoscopic microscopy, SEM and EDS analysis.
