摘要：

Electrical fire occurs due to various causes such as short circuit, overcurrent, poor contact, and tacking. In addition, when a fire from poor contact progresses, the coating of wire is damaged inducing secondary short circuit or ground, which could lead to complex electrical accidents. Therefore, in this study, to investigate the overload mechanism of an electrical fire due to the poor contact of the screw-type connector of a circuit breaker, the temperature characteristics, surface, and composition of the poor contact wire of the circuit breaker were analyzed depending on series arc, and the possibility as a method for electrical fire prevention was examined.
