CalculationsCâu 30 / 110
A commercial building has a 30,000-VA receptacle load. Applying the demand (first 10 kVA at 100%, remainder at 50%), what is the demand load?
a.30,000 VA
b.20,000 VA
c.15,000 VA
d.25,000 VA
Giải thích
First 10,000 VA at 100% = 10,000; remaining 20,000 at 50% = 10,000. Total demand = 20,000 VA.
