Three fixed appliances: Dishwasher 1800 VA, Water heater 6000 VA, Room C 1600 VA. What is the minimum calculated demand load for all appliances?

Explanation:
When calculating the minimum calculated demand load, fixed appliances are added by their rated VA because there’s no factor applied unless otherwise specified. So you simply sum the VA of each fixed appliance: 1,800 + 6,000 + 1,600 = 9,400 VA, which is 9.4 kVA. This makes 9.4 kVA the minimum calculated demand load for all the appliances. The other numbers would require applying a demand factor or different assumptions not provided here.
