example =2.1   

 
 solution for (a)   
connected load = 8X100W+2X60W+2X100W=1120W
 
 solution for (b)   
 
 total wattage at different times is   
	60W
	220W
	0W
	120W
	520W
the maximum demand is 520W
 
 solution for (c)   

demand factor =0.464286
 
 solution for (d)   
	300Wh
	440Wh
	0Wh
	1080Wh
	3120Wh
total energy consumed during 24 hours =300Wh+440Wh+0Wh+1080Wh+3120Wh=4940Wh
 
 solution for (e)   

if all devices are used throughout the day the energy consumed in Wh is 26880Wh 
		26.88kWh
