1. Calculate the estimated demand load in Volt-Amperes and amperes at 240V for residence having
the following characteristics: 2800 sq ft of living space
30 general use receptacle outlets in unfinished areas
3 small appliance branch circuits supplying the kitchen areas
1 laundry circuit
2 dedicated branch circuit supplying outside receptacles
1 Dishwasher: 1/3 hp pump motor, 1000 W dryer element.
Microwave hood: 10 A , 115 V
Refrigerator: 10 A, 115 V
Counter mounted cooktop 5.5 kW, 230 V
Wall mounted oven: 6 kW, 230 V (supplied from same circuit as cooktop)
Air conditioning unit: 30 A, 230 V
Solution
kva = V* I
V is given 240 v
i is calculated for individual householg
i =p/v
