Calculations第 8 / 110 题
A dwelling has four fastened-in-place appliances (dishwasher, disposal, water heater, compactor) totaling 6,000 VA. What is the demand load after applying the fastened-appliance demand factor?
a.6,000 VA
b.3,000 VA
c.7,500 VA
d.4,500 VA
解析
Where four or more fastened-in-place appliances are on the same feeder, a 75% demand factor may be applied: 6,000 x 0.75 = 4,500 VA.
