Lighting circuit load calculation
WebLighting load = Area × unit load = 16,000 × 3 VA per ft.2 = 48,000 VA 210.52 (B) and 220.52 (A) Small-appliance load = 2 × 1,500 VA = 3,000 VA 220.52 (B) Laundry load = 1,500 VA Total lighting load = 48,000 + 3,000 + 1,500 = 52,500 VA Table 220.42, Demand factors for dwelling units Total lighting load = 52,500 VA WebWith a voltage of 120/240, the general lighting load is 48 amperes (5,775 ÷ 120 = 48). To find the minimum number of 15-amperes, 2-wire circuits, divide 48 by 15 (48 ÷ 15 = 3.2 = 4). Because this result is three and two-tenths circuits, the number must be rounded up. At least four 15-amperes, 2-wire circuits are required (see Figure 3).
