A single household electric clothes dryer is rated 4 kW. What value is used for the service/feeder demand calculation?
a.4,000 VA
b.3,000 VA
c.2,000 VA
d.5,000 VA
Explanation
Per 220.54, each dryer is calculated at 5,000 VA or the nameplate rating, whichever is larger. Since 4 kW is below the 5,000 VA minimum, 5,000 VA is used; 4,000 VA and the lower values ignore the minimum.
