Notes:

Data shown for packaged unit installation, with single point power supply.
For split installation with separate evaporator motor power supply, calculate MCA and MFS as follows -
Min. Circuit Ampacity ( MCA ) = 1.25 X Largest motor amps (FLA or RLA) + sum of the remaining motor amps

Max Fuse / Cct. Bkr Size ( MFS ) = 2.25 X Largest motor amps + sum of the remaining motor amps

Select next smallest NEC listed fuse size from calculated value

NOTE:

1. At higher evaporator airflows and wet bulb conditions, condensate carry-over may occur. Adjust airflow downward as necessary.
2. Values include pressure drop from wet coil and clean filters.
3. Shaded areas indicate oversize motors
4. Adjustment limits of standard factory-installed drives are indicated by bold borders. (See pulley data on Pg. 17)
