Planning & EstimatingQuestion 388 of 521
A dwelling's total calculated load is 44,000 VA on a 240 V service. What is the smallest standard service rating that will carry this load?
a.200 A
b.150 A
c.175 A
d.225 A
Explanation
44,000 ÷ 240 = 183 A, so the service must be at least 183 A; the next standard size up is 200 A. A 150 A or 175 A service would be undersized for a 183 A demand.
