Capacitor burning up right away on 220 Volt compressor

I'm putting together a 220 volt compressor. I have a 3 hp motor with 2 capacitors. I wired the motor direct without a load and everything ran great at first. The next day ,when testing a new garage cut-off/breaker I started getting smoke from one of the capacitors. installed a new one with same specs and the new capacitor smoked immediately the motor purrs and spins for a while when the power is cut, seems like the bearings are fine. I don't know what the problem is.Any suggestions?

check the centrifugal starter switch. If it hangs the motor stays in the start windings and will burn your capacitor within a few seconds.

What is the motor? Which cap?
