Solution

Hello ,

I have gone through your problem and giving you aproximate solution for your load demand:

Load for 24 geneal receptacles : 24 X 90 VA=2160 VA

This will not be continues load so :     2160 X 0.75 = 1620

Load for 2 laundry   7000 VA IF WE CONSIDER cONTINOUSE LOAD THAN IT WILL BE APROX 1500 VA.

:2 X 1500VA ( considering Continues ) = 3000 VA

Load for6 dedicated load :6 X 1500VA= 9000 VA    FOR cONTINUES

IT WILL BE 9000 x 1.25 = 11250  

Total Other Loads:840 + 1200 + 1320+ 720 + 7500 + 850 + 4700 + 4560 = 21690VA

Total load : 37560 VA

IN KW : 37110 X 0.8 = 30048 == aprox 30000 W = 30 KW

30 KW
