What is the minimum-calculated demand load for a dishwasher rated at 1800 VA, a water heater at 6000 VA, and a room C at 1600 VA?

9400 VA
8000 VA
7500 VA
10000 VA

The correct answer is: 9400 VA

To find the minimum-calculated demand load for the listed appliances, you add the rated loads of each appliance together. For the dishwasher, the rated load is 1800 VA. The water heater has a rated load of 6000 VA, and room C contributes 1600 VA. Adding these values together gives you: 1800 VA (dishwasher) + 6000 VA (water heater) + 1600 VA (room C) = 9400 VA. This calculation reflects the total maximum demand on the system from these devices when all are potentially in use. Therefore, the minimum-calculated demand load for this scenario is 9400 VA, making it the correct answer. In terms of the other choices, 8000 VA, 7500 VA, and 10000 VA do not accurately represent the total load based on the provided ratings. This confirms that the correct calculation of 9400 VA is crucial to adhere to proper electrical design and safety standards.
