What size start capacitor?
Capacitors come in various sizes, your question is to non specific (capacitor for WHAT) for a detailed answer.
What is the differencebetween a run capacitor and start capacitor?
The run capacitor is used when the load is functional while the start capacitor is used to produce the initial torque to drive the load.
What is a split phase motor with relay and capacitor called?
A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".
Can you change a 440 volt 12.5 uF start capacitor with a 370 volt 12.5uF run capacitor?
There are two ways to read this: you have a burned-out run capacitor on your motor and a good start capacitor in your parts box, and you have a burned-out start capacitor and a good run capacitor. If the run capacitor's bad and you want to put the higher-voltage start cap in its place, the answer is yes. This is called derating, and the only thing it does for you is increases the lifespan of the capacitor because you're not working it as hard as it can take. If the start capacitor's bad, don't do this--they used a 440-volt capacitor in there for a reason.
How do you know if start capacitor de-energized after start up?
You can determine if a start capacitor has de-energized after startup by checking for a voltage drop across the capacitor terminals using a multimeter. If the voltage is close to zero or significantly lower than the rated voltage after the motor has started, the capacitor has likely de-energized. Additionally, some systems have built-in indicators or relays that disconnect the capacitor once the motor reaches a certain speed. Lastly, a visual inspection for signs of overheating or damage can also indicate proper function.
What size start capacitor?

Will capacitor size increase if the voltage rating oes up?
Yes.
What happens when start capacitor is slightly over sized?
C=QV it doesnt depend on size.
Can you by-pass a capacitor in an electric motor?
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
Can you use a run capacitor in place of a start capacitor?
No
What is the differencebetween a run capacitor and start capacitor?
The run capacitor is used when the load is functional while the start capacitor is used to produce the initial torque to drive the load.
What are the starting and running characteristics of a capacitor-start motor?
Easier to start up. Running remains the same unless it is equipped with a run capacitor too. A run capacitor uses a little less current during run and probably runs a little cooler too.
What is a split phase motor with relay and capacitor called?

What size capacitor do you need for a 1 ton compressor?
For a 1-ton compressor, you typically need a capacitor rated between 30 to 40 microfarads (µF) for the start capacitor and around 5 to 15 µF for the run capacitor, depending on the specific model and manufacturer. It's important to consult the compressor’s specifications or user manual for the exact capacitor size required. Always ensure that the voltage rating of the capacitor is sufficient for your application, generally around 370 volts or higher for HVAC systems.

How do you connect capacitor to a capacitor start motor?
A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding. A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.
Can a starting capacitor lower a fridge starting draw from 2400 watts to 800 or less without damaging the motor and how can the size of capacitor needed be determined?
If you lower the start cap size it may take milliseconds longer to start so it will still use the approximate same amt of power. Size? search for "appliance repair parts" enter your model number and you may be able to locate the value of the start cap. go from there.
