Planning & EstimatingQuestion 362 of 521
A dwelling calculated load totals 24,000 VA on a 240 V, single-phase service. What is the minimum service ampacity this load demands?
a.60 A
b.90 A
c.100 A
d.125 A
Explanation
Amps = VA ÷ volts = 24,000 ÷ 240 = 100 A. Dividing by 120 or using the wrong voltage produces the other values, so the calculated demand is 100 A.
