What is the total nameplate load (in kW) of three ovens rated 6 kW, 8 kW, and 3.5 kW, plus a cooktop rated 6 kW?

• A. 23.5 kW
• B. 27 kW
• C. 23 kW
• D. 24 kW

Answer: (A)

Adding the maximum power ratings of each appliance gives the total nameplate load. For these devices, sum the kW ratings: 6 + 8 + 3.5 + 6 = 23.5 kW. So the total nameplate load is 23.5 kW. Rounding to 24 kW would lose precision, and the other numbers don’t match the exact sum. In practice, this sum is used to size feeders or service, though simultaneous usage may be less due to diversity.
