The following sections provides the formulas and the data to calculate the Minimum Circuit Ampacity (MCA) and the Maximum Fuse Size (MOP) for your specific unit configuration. Please note that the UCA Select software can also be used to calculate the electrical data for the VertiCool Aurora units�There are a variety of unit configurations. Please make sure to use the correct formulas per your configuration.It must be noted that the formulas refer to the largest motor amps� This typically is the compressor (RLA), but it can also be one of the blower motors (FLA)�The data provided will cover the majority of available unit configurations. However, it should be noted that additional combinations may be available and the factory can be contacted for this data�Examples have also been provided for each configuration.

RLA = Compressor Rated Load Amps FLA = Full Load Amps (Used for Blower Motors and Electric Heaters) MCA = Minimum Circuit Ampacity (Calculated value) MOP = Maximum Fuse Size (Calculated value)
