NOTES:
1. RLA - Rated Load Amps are calculated as per UL1995.
2. MCA - Minimum Circuit Ampacity is: [ 125% of the RLA of the largest compressor motor plus 100% of the RLA of all other concurrent motors and/or electrical loads].
3. MOP - Maximum Overcurrent Protection or Max.Fuse Size is rounded down from: [ 225% of the RLA of the largest compressor motor plus 100% of the RLA of all other concurrent electrical loads].
4. Recommended Dual Element Fuse Sizing: Rounded up from 150% of the RLA of the largest compressor motor plus 100% of the RLA of all other concurrent electrical loads.
5. LRA - Locked Rotor Amps are instantaneous starting amperage per compressor.
6. Module internal wiring is per NEC.
7. Voltage Tolerance Range
208-230V / 60 Hz: Min. 187V Max. 253V
460V / 60 Hz: Min. 414V Max. 506V
575V / 60 Hz: Min. 518V Max. 632V
8. MOP Device or Recommended Fusing Device for Module Power Wiring supplied by others. These are recommended values for electrical power protection of Modules selected.
9. Disconnect Switch for Module Power Wiring supplied by others. These are recommended values for electrical power protection of Modules selected.
