10 UFD @ 250 VAC is the device specs. It is used as a start capacitor,
function is to lessen the electrical current through the start winding of
the motor. Should be able to appropriate capacitor at any industrial motor
service or HVAC facility. Even able to be ordered off the web if you
google
for "start capacitors".


It depends on the type of motor, but it's purpose is to offset the phase of
the start winding in order to create a rotating magnetic field. It does
limit the current somewhat but that's not it's primary purpose.

I usually get motor caps from HVAC surplus dealers, they're a fraction of
new cost.
