Just want to make sure I have this right. I'm getting myself confused on Full-Rated vs. Up-Rated motors. I know how to calculate total horsepower. I'm just not sure which is which.
The motor is going out on my Hayward Super II pump. The current motor is labeled 1.5HP with a Service Factor of 1.33 (1.5 x 1.33 = 1.995). Is this considered a "Full-Rated" motor? And if I get an "Up-Rated" motor, do I then have to get a 2HP up-rated motor?
It also seems like up-rated motors are a bit cheaper than full rated motors. I had read that full-rated motors have more copper. Does this mean that full-rated motors last longer? Does one type of motor (assuming same total HP) use more electricity that the other?
