Electrical Data The following sections provide the formulas and the data to calculate the Minimum Circuit Ampacity (MCA) and the Maximum Overcurrent Protection (MOP) for a variety of unit configurations. The formulas refer to the largest motor amps. Typically this is the compressor (RLA) but it can also be one of the blower motors (FLA). Please note that the UCA Select software program is also available to calculate electrical data and provide unit submittals, drawing reports and pricing information. Cooling Only: NOTE: Largest motor amps may not always be the compressor. MCA = (1.25 x largest motor amps) + the sum of the remaining motor amps MOP = (2.25 x largest motor amps) + the sum of the remaining motor amps Note: Round calculated MOP value down to the nearest 5 amp increment. Packaged OmegaAir Unit - Water-Cooled (can be single or dual compressor) EXAMPLE 1: EXAMPLE 2: 2 Ton Water-cooled, 208/230-3-60 6 Ton Water-cooled, 460-3-60 Single Compressor RLA = 8.3 Dual Compressors RLA = 6.0 each Evap Blwr. Motor (1/4 HP) FLA = 1.3 Evap Blwr. Motor (3/4 HP) FLA = 1.5 MCA = (1.25 x 8.3) + 1.3 = 11.7 MCA = (1.25 x 6.0) + 6.0 + 1.5 = 15.0 MOP = (2.25 x 8.3) + 1.3 = 19.98 calculated MOP = (2.25 x 6.0) + 6.0 + 1.3 = 20.8 calculated MOP = 15 (rounded down to nearest 5) MOP = 20 (rounded down to nearest 5) Split-system OmegaAir, matched w/ Indoor Ducted Air-Cooled Condenser (can be single or dual compressor) EXAMPLE 3: 8 Ton OmegaAir, 208/230-3-60 8 Ton Indoor Ducted Condenser, 208/230-3-60 Dual Compressors RLA = 16.0 each Cond Blwr. Motor (3 HP) FLA = 8.8 Evap Blwr. Motor (1 HP) FLA = 4.0 MCA = (1.25 x 16.0) + 16.0 + 4.0 = 40.0 MCA = (1.25 x 8.8) = 11.0 MOP = (2.25 x 16.0) + 16.0 + 4.0 = 56.0 calculated MOP = (2.25 x 8.8) = 19.8 calculated MOP = 55 (rounded down to nearest 5) MOP = 15 (rounded down to nearest 5) Cooling with Electric Heat: On equipment with multiple modes of operation (i.e. cooling and heating), each mode must be evaluated and whichever load condition provides the highest value shall be used. NOTE: Largest motor amps may not always be the compressor. Use the larger of the following: MCAclg = (1.25 x largest motor amps) + the sum of the remaining motor amps MCAhtg = 1.25 x (heater amps + evap motor FLA) MOPclg = (2.25 x largest motor amps) + the sum of the remaining motor amps MOPhtg = (2.25 x evap motor FLA) + heater amps Note: Round calculated MOP value down to the nearest 5 amp increment. MOP must be greater than MCA. If the rounded MOP is less than the MCA, then the MOP is equal to the MCA value rounded UP to the next 5 amp increment. Subject to change without notice. 18
