[AC] Replaced capacitor, now unit tripping plug breaker?
Run capacitors do not hold a charge when the compressor is off, they discharge themselves through the motor windings of the compressor. When not in the circuit, a motor winding is just an electric resistor. If you get shocked by a run capacitor or it ever does have a spark then there is usually something wrong with the motor it''s hooked up to.

A little more info: When the relay applies the 230 volts to the motor the sound from the motor is a buzzing sound for a second or two before the breaker trips. It does not sound as if the motor is trying to spin at all even though the start capacitor checks out fine.

What is a capacitor trip device?
Capacitor trip devices are commonly used in switchgear to provide trip circuit power and to provide voltage sag ride through capability for digital relays. CTD is not commonly used for closing applications as it is expected that the normal control power will be available when closing is desired.
What is the voltage of a CTD capacitor?
Voltage on capacitor will be the peak voltage of input AC waveform. For 120VAC input, output voltage will be 120*sqrt (2) = 120*1.414=169VDC. For DC input CTD, output voltage will have the same magnitude voltage as input. Can CTD be used as a DC power supply?
What is CTD capacitance?
CTD capacitance could be anywhere from 330uF to 4500uF with larger capacitance translating in to more stored energy and more trip operations. When AC input is lost, DC power is immediately available to load as there are no relays or switches in CTD. On initial energization, DC power is immediately available even before capacitors are fully charged.
What happens if a capacitor is charged before energization?
On initial energization, DC power is immediately available even before capacitors are fully charged. Capacitors are typically charged to 90% voltage in less than 0.5s when CTD is turned ON from a discharged state. In figure 2, Thermistor ‘T’ is used to protect against short circuits and overloads.
What is the function of capacitor 'T' & diode 'D1'?
Capacitors are typically charged to 90% voltage in less than 0.5s when CTD is turned ON from a discharged state. In figure 2, Thermistor ‘T’ is used to protect against short circuits and overloads. Diode ‘D1’ performs half-wave rectification along with capacitor ‘C’.
