Fires in the fire switchboard are constantly occurring and efforts are being made to improve them. Most of the causes of fire in switchboards are due to poor contact at terminals, dust and water inflow. Among them, we have checked the possibility of fire caused by water inflow through fire cases, installation status, and combustion experiments. We have also confirmed that there are no specific criteria regarding electrical equipment, although the technical standards of the Ministry of Trade stipulate that “the structure would not allow water to permeate into the distribution box.” Therefore, this study warns of fire hazard caused by water inflow switchboard through the results of fire reproducibility experiment, and it expects that the supplementation of laws to improve the environmental factors that bring moisture into switchboard. We hope that the fire investigation will develop from the center of ignition source and factor to the center of fire prevention measures and contribute to fire prevention.
