I hope that someone can help answer this question;
When calculating the required size of a dwelling unit using the "general" method of calculation to comply with 430.24 the largest motor in FLC is increased by 25%.
Can anyone point me to a hard and fast rule about whether or not an air-conditioner should be used at this step (if the air conditioner was not omitted) per 220.60?
I have taken several exams and have always used the air conditioner if it was indeed the largest motor in FLC and didn't get omitted per 220.60. Now I never did get to see which questions were answered right and which were wrong, but I always passed the exams using this method.
I am now having differences of opinion with other instructors as they say that an air conditioner can't be used for this step as it is technically a hermetic refrigerant motor-compressor and not a "motor". I say it's a motor just a motor of a different type which should be used for the 25% increase rule if not omitted.
What say you?
