Electrical Notes
Notes for “Electrical Data Single Point” Power:
1. Unit wire size ampacity (MCA) is equal to 125% of the largest compressor-motor RLA plus 100%
of RLA of all other loads in the circuit including the control transformer.
2. If the control transformer option is furnished, no separate 115V power is required.
3. If a separate 115V power supply is used for the control circuit, then the wire sizing amps is 10
amps for all unit sizes.
4. Recommended power lead wire sizes for 3 conductors per conduit are based on 100% conductor
ampacity in accordance with NEC. Voltage drop has not been included. Therefore, it is
recommended that power leads be kept short. All terminal block connections must be made with
copper (type THW) wire.
5. “Recommended Fuse Sizes” are selected at approximately 150% to 175% of the largest
compressor RLA, plus 100% of all other loads in the circuit.
6. “Maximum Fuse or HACR breaker size” is selected at approximately 225% of the largest
compressor RLA, plus 100% of all other loads in the circuit.
7. The recommended power lead wire sizes are based on an ambient temperature of 86°F (30°C).
Ampacity correction factors must be applied for other ambient temperatures. Refer to the
National Electrical Code Handbook.
8. Must be electrically grounded according to national and local electrical codes.
9. MCA may vary slightly due to fan motor options such as SpeedTrol, TEFC.
Voltage Limitations:
Within ± 10 percent of nameplate rating.
