I have a Hayward pool pump where the start cap is 161-193 uf. How can you have a range of capacitance. Hayward is an american company. so maybe it can run on 110v or 240v. (just a guess). The other issue is ceiling fan caps, now these are start/run caps and I know from past experience that you can burn out the motor by fitting too high a cap eg was 2.5uf only had a 3.0uf in stock (goodbye fan). But yesterday I had a 1.8uf bad cap & fitted a 2.0uf . The customer is now saying that there is a smell when on high speed. Why are the ratings of fan caps so critical when on other induction motors ie pumps,washing m/c motors you can fit 30uf instead of 25uf with no ill effect.
Thanks Mack.
