An air-conditioning circuit has a 24-ampere compressor and a separate 4-ampere fan motor. Using 125 percent of the largest motor plus the other motor, what ampacity results?

A28 amperes
B30 amperes
34 amperes
D35 amperes

Why C is correct

Apply 125 percent to the 24-ampere compressor and add the 4-ampere fan: 24 × 1.25 + 4 = 34 amperes. Keep units consistent and use only the factors stated; no optional method or unstated demand factor is assumed.
