What is the difference between 370 vac and 440 vac capacitors?
Txtoolgirl
The difference is that the 440 vac capacitor has a 70 volt-amp-current higher output than the 370. Capacitors must always be replaced with the same size micro-farads or you'll damage the device, such as a motor. The vac rating can be changed with a capacitor with a higher rating but not lower.
Example: 15mfd at 370vac can be replaced by a 15mfd at 440vac, but not the opposite.

Will a 370 VAC motor run using a 440 VAC capacitor?
If the motor is rated at 370 v and the supply is 370 v, the capacitor needs to be rated at 370 or more volts, so a 440 v capacitor will be OK.
Why don't they just use 440 vac capacitors for all condensers and get rid of 370 vac capacitors?
Because when a fan motor (or compressor), is designed to operate on a 370 VAC run capacitor, that will be its optimal efficiency operating design. We're talking about capacitors used on an A/C in a typical 230 volt power supply to a residence or business. If you substitute a 440 VAC run cap in place of the 370 cap, the motor will seem to operate just fine. However, if you put an amprobe on the motor, you will find an increase in the amps it is drawing. This translates to increased heat in the windings, and some motors can handle a small heat rise while others have a problem with it. It partly depends on the airflow over the fan motor along with the quality of the motor, but in any event, you are decreasing the life of the motor along with paying for the electrical current you're wasting, and also, not using the specified cap the motor calls for, in most cases, will void the motor's warranty. The worst place to substitute a 370 VAC cap with a 440 VAC cap is on a compressor. The increased heat load in the windings causes an increase in head pressure and on some compressors already operating at high head pressure and heat load, the compressor can trip off and will stay off until the shell cools down. Of course, the additional amp draw in the compressor will really drive up the power bill. Bottom line, use the cap the motor specs call for. If you have to substitute to get-by because you don't have the right one on your truck, go back the next day and put the right one in. George Henne--Retired A/C Tech----
Why 440 volts running capacitor if my ac is 230 volts?
The 440 volts listed on the cap is the maximum allowable voltage the capacitor can handle. You could actually use a 370 volt cap on 230 volts. ANSWER; 230 volts AC can it actually be 644 volts peak to peak . It is 44ov because it must be rectified and sees only 324 volt peak which is withing the 440 volt capacitor handling voltage

Will a 370 VAC motor run using a 440 VAC capacitor?
If the motor is rated at 370 v and the supply is 370 v, the capacitor needs to be rated at 370 or more volts, so a 440 v capacitor will be OK.

The air conditioning work in 230 volt why the compressor use capacitors of 370 and 440 volts if he only need mfd to start?
An AC capacitor is composed of two DC capacitors with the foil ends (-) connected together and the center ends (+) connected to the outside. There are variations to the connections. Each capacitor has to have the voltage rating required by the application -- and there are two capacitors in series in an AC capacitor. A 230V AC capacitor, depending on manufacturing design standard, may not be suitable for starting a 230V air conditioner.

What is the difference between the number of inches in a quarter mile and the number of inches in 880 yards?
880 yards is half a mile so the difference between the two distances is a quarter of a mile. 1/4 mile = 1/4*1760 yards = 440 yards = 440*36 inches = 15840 inches.
