    Capacitor under sized



    I have a 575 volt single phase condenser fan motor with a 370 volt capacitor.This comes O.E.M. from Carrier.It periodically blows the capacitor,in neighbouring units too...
    Any thoughts?

    A capacitor must always be correct sized and even beterr oversized.
    I should contact Carrier for this because this is a warranty case.

    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

    Re: Capacitor under sized

    Its a run capacitor,the motor voltage is 575v.
    I am wondering if the capacitor only sees one leg of the 575 voltage,which would be approxiamately 347 volts?
