11 Electrical Data 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. 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) Cooling Only: Package Unit NOTE: Largest motor amps may not always be the compressor. MCA = (1.25 x largest motor amps) + the sum of the remaining motors MOP = (2.25 x largest motor amps) + the sum of remaining motors Condensing Section w/ Compressor(s) NOTE: Largest motor amps may not always be the compressor. MCA = (1.25 x largest motor amps) + the sum of the remaining motors MOP = (2.25 x largest motor amps) + the sum of remaining motors Evaporator Only Section MCA = (1.25 x Evap.

Electric Heat On equipment with multiple modes of operation (i.e. cooling or heating), each mode shall be evaluated and whichever load condition provides the highest value shall be used. Use the larger of the following: MCA = (1.25 x largest motor amps) + the sum of the remaining motors or MCA = (Heater FLA + Evap. Motor FLA) x 1.25 MOP = (2.25 x largest motor amps) + the sum of the remaining motors or MOP = (Evap. Blower Motor x 2.25) + Heater Amps Evaporator Only Section Electric Heat MCA = (Heater FLA + Evap. Motor FLA) x 1.25 MOP = (Evap.
