NOTES:
1. 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.
2. Single point power supply requires a single fused disconnect to supply electrical power to the unit.
3. Multiple point power supply requires three independent power circuits with separate fused disconnects. (Two compressor circuits,
one control circuit) and is a factory special.
