Question 203Electricity & Electronics - QMED

The correct answer is B) 1.15. The service factor, as shown in figure "A" of the illustrated motor nameplate, represents the multiplier that can be applied to the motor's rated horsepower to determine the maximum safe operating load for the motor. A service factor of 1.15 indicates that the motor can be safely operated at up to 115% of its rated horsepower without exceeding the motor's design limits. The other answer choices are incorrect because: A) 1.00 would represent the motor's rated horsepower, not the service factor; C) 17.5 is not a typical service factor value; and D) 89.7 does not correspond to the information provided in the illustration.
