To get the Total RLA s for multiple module units, multiply the single module the Total Rated Load Amps of one module by the numbers of modules. 2. 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. 3. 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. 4. Recommended Fuse Sizes are selected at approximately 150% to 175% of the largest compressor RLA, plus 100% of all other loads in the circuit. 5. Table based on 75 C field wire. 6. A HACR breaker is a circuit breaker designed for use on equipment with multiple motors. It stands for Heating, Air Conditioning, and Refrigeration. 7. 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. 8. Total Rated Load Amps includes all compressors and fans. Figure 3, Field Wiring Diagram The wire gauge should be sized accordingly to the power consumption of all the Modules.
