As power source electric has served in various fields of production and life and cause a new kind of disasterselectrical fire. In present prosperous economy situation of cities and towns day by day, the damage caused by electrical fire has gown with each passing day.In highrise building, all kinds of electrical and electronic systems with wires in length and breadth densely covered are so plex that chance of fire is high. Electrical equipments and wires have been main burning source in highrise building. Electrical fire has many direct reasons including overload, shortcircuit, aid contact failure.This thesis analyzed design and construction reasons of electric that cause the electrical fire aid found out weak links of power supply and distribution systems of highrise civil buildings. This thesis based on several theories including generating heat and calcula
