What is the maximum voltage rating for the capacitors mentioned?

The maximum voltage rating for the capacitors referenced in residential air conditioning systems is 370VAC. This rating is significant because it indicates the highest voltage these capacitors can safely handle in alternating current (AC) applications without risk of failure or damage.

Using capacitors with a voltage rating lower than the system's voltage can lead to overheating, dielectric breakdown, or catastrophic failure, which can be both dangerous and costly. In most residential systems, components like compressor start and run capacitors are often specifically rated at 370VAC, designed to work efficiently under typical operating conditions.

Other voltage ratings like 440VAC or 600VAC are typically used in different applications or commercial settings where higher voltage capacities are needed, while 220VAC rating is insufficient for most residential air conditioning systems, which usually operate at higher voltages. Hence, 370VAC is the most appropriate rating for typical residential air conditioning capacitor use.
