I want to know something a circuit it is a DB with switches what is confusing is how the load was calculated and what formulas are used.

All switches have Amp shows 10 A to 20 A on 240 Supply line ( LT line is 220 – 240 V )
Detail of switches
10 of 10A
5 of 20A ( For Air Conditioners )
3 of 15A ( for power sockets )
Total No. of switches 18
Total load is calculated and given is 18.80

How did they calculate it.
