In the appliance demand calculation example, what percentage factor is applied to the sum of appliance ratings?

• A. 50%
• B. 100%
• C. 125%
• D. 150%

Answer: (B)

The key idea is how the appliance portion of the load is determined in the demand calculation. In this example, you take the sum of all appliance ratings and apply a factor to that sum. Using 100% means you use the full, unadjusted total—the appliances are considered capable of reaching their combined rated load, with no reduction or increase. This baseline approach keeps the appliance load equal to the simple sum of ratings. If you used a lower factor, it would imply some diversity or simultaneous-use reduction, and a higher factor would overstate the load beyond the sum of the ratings. Since the example demonstrates using the full sum without any adjustment, the correct factor is 100%.
