For AC inductive loads (such as solenoids, contactors coils, etc.) the re-
duction factor corresponding to cos(p.f.) (cosine of the power factor) is
multiplied by the rated current in order to identify the maximum allowable
current. This approximation is not valid for loads with high inrush cur-
rents such as electric motors or fluorescent lamps.
