Planning & EstimatingQuestion 382 of 521
Using the optional method, a dwelling's 220.82(B) other loads (general lighting, appliances, etc., excluding heating/AC) sum to 40 kVA. What is the calculated demand for that portion?
a.40 kVA
b.16 kVA
c.22 kVA
d.18 kVA
Explanation
Apply 100% to the first 10 kVA and 40% to the remainder: 10 + (30 × 0.40) = 10 + 12 = 22 kVA. Taking 40% of the entire 40 kVA (16 kVA) skips the first-10-kVA block.
