Correct answer to question 12025
- A: 19,280 VA
Explanation
General loads at nameplate: 6,000 VA lighting (3 VA/ft2) + 4,500 VA small-appliance and laundry + 12,000 + 5,000 + 1,200 + 4,500 = 33,200 VA (220.82(B)). The first 10,000 VA count at 100 % and the remaining 23,200 VA at 40 %, giving 19,280 VA.
