A dwelling's general lighting plus small-appliance/laundry load totals 13,500 VA. Using the standard demand factors (first 3,000 VA at 100%, remainder at 35%), what is the demand?
a.4,725 VA
b.6,675 VA
c.13,500 VA
d.3,000 VA
Giải thích
First 3,000 VA at 100% = 3,000 VA; remaining 10,500 VA at 35% = 3,675 VA; total = 6,675 VA. 13,500 VA ignores demand factors, and the other values misapply them.
