How do i size up a start capacitor?

Read the capacitor that you remove

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.

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.

What is the fill material in a start capacitor?

oil

Can you replace 1.7 microFarad capacitor with 2 microFarad capacitor of capacitor start motor?

It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.

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

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.
