Correct answer to question 12009
- A: 5
Explanation
For counting branch circuits the dwelling unit load stays at 3 VA per ft2 (120.13): 2,600 x 3 = 7,800 VA. Each 15 A, 120 V circuit carries 1,800 VA, so 7,800 / 1,800 = 4.33, rounded up to 5 circuits. The 2 VA value of 120.41 applies only to service and feeder calculations.
