I'd bet dollars to donuts it's a PSC (permanent split phase capacitor)
motor. This has two windings. A capacitor is switched from one winding to
the other which will make the motor reverse even while running. See

It's a good choice for this service. It could also be a cap start, cap run,
but they are harder to stop and reverse.

Could be 120 or 240 if the two breakers are locked together so opening one
opens the other. You don't need a grounded line if the motor is 240V. What
does the nameplate say?
