Correct answer to question 12022
- B: 5,625 VA
Explanation
Lighting is 2,000 x 3 VA = 6,000 VA, plus 2 x 1,500 VA small-appliance and 1,500 VA laundry gives 10,500 VA (Table 220.12 in 2020, 220.41 in 2023, 220.52). Applying the dwelling demand factors (Table 220.42 in 2020, Table 220.45 in 2023): first 3,000 VA at 100 % plus 7,500 VA x 35 % = 5,625 VA.
