NOTES:
1. Unit wire sizing amps are equal to 125% of the largest compressor-motor RLA plus 100% of the other compressor RLA's.
2. Multiple point power supply requires a separate fused disconnect for each circuit to supply electrical power to the unit.
3. External compressor overload option is only available for units with 140° F maximum leaving condenser water temperature.
4. Wire sizes shown above are for standard ambient temperature and short runs of wire.
