Evaluation of Fire Hazard in Electrical Installations Due to Unfavorable Ambient Thermal Conditions

Evaluation of fire hazard caused by electrical installations is a difficult and important topic, it limits the possibility loss life or health people, as well occurrence significant property damage. In particular, this was power cables especially photovoltaic (PV) installations. The authors proved that directly exposed to strong solar radiation are likely exceed maximum permissible temperature in unfavorable ambient conditions. Overheated damaged cable insulation can be source electric shock leakage current causing fire. case typical PV connectors (MC4 connectors), main problem poor contact at connections cables. A connection even cause connector melt, shown study. paper, present computer simulation regarding critical thermal points installations, type. It may an indication what should paid attention when designing implementing such This for safety people buildings.
