## Questions & Answers

**Q: What does "708-850 uF" mean?**
A: "708-850 µF" in a motor run capacitor spec means it has a capacitance range of 708 to 850 microfarads (µF), determining its ability to store electrical energy. This range should match the motor's requirements for optimal operation.

**Q: Can I replace a Motor Start Capacitor with a Motor Run Capacitor?**
A: Start capacitors give a large capacitance value necessary for a motor to start for a very short period of time (usually seconds long). A start capacitor can never be used as a run capacitor because it cannot handle current continuously.

**Q: I've installed the Capacitor, but my machine is still not functioning properly. What's the issue?**
A: There might be several reasons for this such as: Incorrect installation, faulty motor, capacitor compatibility or other electrical issues. If the issue persists, please don't hesitate to reach out. We're here to help.

**Q: Can a motor start capacitor rated 110-125 volts be hooked up to a 220 volt line input? Will it just burn out?**
A: No. The voltage rating of a capacitor indicates the maximum voltage that it can handle safely. If you put a 110-120 capacitor where a 220V is required, it may start the motor a couple of times but will fail very soon.

**Q: Can I repair the faulty Capacitor?**
A: Capacitors are typically not designed for repair and are considered disposable components. We recommend you to replace by a new one.
