A service calculation contains 84 amperes of noncontinuous load and 32 amperes of continuous load. Ignoring other demand factors, what calculated current results?

124 amperes
B116 amperes
C145 amperes
D105.6 amperes

Why A is correct

Apply 125 percent only to the continuous portion: 32 amperes times 1.25 equals 40 amperes. Add the 84-ampere noncontinuous portion to obtain 124 amperes.
