    I have an old chipper/shredder that has a drum motor. it does have capacitor, which I believe to be a run capacitor because there is no centrifugal switch in the motor. the 4 wires coming from the motor are black, blue, pink and green/yellow stripe. From what I understand this motor is Swiss made. Am I wrong to think that this is a RUN capacitor? Also what is the difference between a "start" and a "run" capacitor. While I'm at it, the capacitor that is installed on the motor is a 80uf 250 vac 60hz. So would it be ok to install a 80uh with a higher voltage rating like a 480 volt cap.

    The answer to start/run capacitor was already posted in the post you responded to but somehow completely missed the very clear definitions at the beginning of the post.

    and yes a higher voltage cap should not be a problem here.

    Sorry for my ignorance. Sense the motor has no centrifugal switch, then i can assume the the cap is a "run cap"?
