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
Dual
Compressors RLA = 19�2 each
Evap
� Blower Motor FLA = 4�8
Cond
� Blower Motor FLA = 9�2
MCA
= (1.25 x 19.2) + 19.2 + 4.8 + 9.2 = 57.2
MOP
= (2.25 x 19.2) + 19.2 + 4.8 + 9.2 = 76.4
