A one-family dwelling has 2,000 ft² of habitable floor area. Using the standard method, what is the general lighting and general-use receptacle load?
a.6,000 VA
b.4,000 VA
c.9,000 VA
d.3,000 VA
Giải thích
Dwelling general lighting is calculated at 3 VA/ft², so 2,000 ft² × 3 VA/ft² = 6,000 VA. 4,000 VA would use 2 VA/ft² (wrong value), and 3,000 VA is only the small-appliance/laundry portion, not general lighting.
