<Prevention of electrical accidents in building facilities>
As mentioned above, for example, the power receiving and transforming equipment is equipped with a vacuum circuit breaker, high-voltage load switch (fuse), high-voltage cutout, etc. And prevent electrical accidents. However, a fire has occurred due to insufficient tightening of screws due to deterioration over time or inconvenience of construction, loosening of connection terminals, gaps, incorrect wiring, dust, etc. and poor insulation of the insulation coating, and it seems that it is still insufficient. In addition, a breaker is not usually installed in the extension cord between the distribution board, distribution board and equipment, and equipment, or the junction box for branch wiring connection and the extension cord after that, and it is due to a short circuit or the like. There are also cases of electric fire accidents.
