This article is a study to identify the various causes of electric fire that could occur at the terminal stage, such as poor contact and the risk of fire due to over-current. First, the fire hazard was tested for poor contact, over-current, or single cause, and then the thermal characteristics of the tightening torque changes were tested, assuming that the two causes occurred simultaneously. The experiment showed that the thermal characteristics of the terminals were significantly more apparent when the two causes worked in combination, and that the risk was higher.
