A: = Common C because its Not all motors use start/run caps; Double run capacitors can power two motors such as a fan and compressor and are ideal for heat pump units and larger air conditioners. In our capacitor testing and wiring sketch above and in our explanatory table below, you note we use the letters S, C, and R to identify the usual terminals to which a start/run capacitor is wired. 2. A refrigerant is a cooling fluid residing in an AC's coils. The capacitor is wired between the power source and the compressor. A start device matched with an appropriately sized capacitor to cover the range of compressors for the intended application (one size does not fit all). Sorted by: 1. This is usually indicated by a battery symbol. 2. Wire - Wires are usually represented by solid lines. Due to the combined gas law (a combination of Boyles Law, Charles Law, and Gay-Lussacs Law), which states that if pressure increases so does its temperature, when you compress the refrigerant, it will heat up. Most capacitors range from 5 MFD (microfarads) to 80 MFD. Once you have the required information, you can wire the capacitor in series with the AC power supply. [1] "The E Class Advantage", Supco (op cit), describes the company's advanced start/run capacitor products.
