In a working capacitor ohms will build-up and then fall off (when the capacitor discharges). as a general rule of thumb, electric motor start capacitors can be replaced with a micro-farad or µF or mfd rating equal to or up to 20% higher µF than the original capacitor serving the motor. Many motors use start capacitors to regulate the electrical components of the motor during the start process. Run capacitors typically range in micro-farads from 1.5 to 50µF. A common complaint is slow startup, usually needing a “push” to get it up to speed. Using a motor run capacitor will run the motor with greater efficiency. the uf changes the line voltage to the unit to hold the speed the motor is running. If capacitors are wired in parallel the total capacitance (microfarad rating) is equal to the sum of the individual capacitors. This happens when the start capictor remained engaged too long - perhaps because a centrifugal switch inside the motor did not disengage the starting cap circuit when it should-have. Wear work gloves and use a screwdriver with an … ShreeThank you for helpful question.It takes a much bigger kick or jolt of current to start a motor spinning from being idle than it does to help keep the motor spinning once it is started.

If a failed start capacitor is discovered while troubleshooting, the start relay should be inspected as the possible cause. Where in Korea ? This category contains Motor Start Capacitors. Extra caution should be observed when employing the "one-size-fits-all" and "a bigger capacitor is better" approach to applying a start device. The operation is similar to a split phase in that there is a start switch to take the start winding and capacitor out of the circuit once the motor reaches 2/3 to 3/4 of full speed. This AC motor start capacitor is suitable for single phase submersible pumps by Sta-Rite, Berkeley, Pentek Pentair with capacitor start and capacitor run (CSCR) control boxes. van Roon, Tony, "Capacitors", [online article], retrieved 6/20/14, original source: http://www.sentex.ca/~mec1995/gadgets/caps/caps.html, gives a very detailed history of the invention and history of electrical capacitors beginning with van Musschenbroek's Leyden jar in 1745. Rated capacitance for a capacitor is the capacitance value (electrical energy storage value) for which the capacitor is designed. I have all the ID data on the capacitor which is AERONOX RFFU, 170015, 15mfd 330VAC, 132.
