A 7 storey building has a floor area of 35,000sq.ft on each storey. On the ground floor 11KV electrical sub-station is to be erected. A load of 3kw for every 400sq.ft (p.f is 0.8) is proposed for each floor. fire pump 7.5hp, water pump 5hp, lift 2 nos, each 10hp and 20shop load of each shop is 5kw. calculate a. load each floor b. total load of building c. L.T feeders for aech floor and from transformer to main. d. distribution diagram e. capacity of sub-station/capacitor bank f. line diagram
