NOTES:
1. Compressor RLA values are for wire sizing purposes only and do not reflect normal operating current draw.
2. Compressor LRA values for part winding start are for the first winding.
3. Unit wire sizing amps are equal to 125% of the largest compressor-motor RLA plus 100% of RLA of all other loads in the circuit
including control transformer. Wire size amps for separate 115V control circuit power is 11 amps.
4. Single point power supply requires a single fused disconnect to supply electrical power to the unit.
5. Supplemental overloads are used in conjunction with standard inherent overload protection. The supplemental overloads:
• Reduce wire sizing amps
• Add additional protection
• Lower compressor amperage
6. Part Winding Start is a special option on 460 and 575 volt units.
