*kW does not include motor watts.

Ampacities and over current protection based on largest air handler motor load. Refer to specific name plate for exact ampacity and overcurrent protection size. 

Minimum wire ampacity values are used for sizing field power conductors.  Refer to the National Electrical Code (latest version), Article 310, for sizing conductors. When more than three current-carrying
conductors are in the same conduit, the conductor’s ampacity MUST be derated. See Note 8 of Table 310 for ampacity adjustment factors. 

Maximum size fuse or HACR-type circuit breaker for field wiring protection.

Wire size based on 75°C copper wire with no more than three current-carrying conductors in the same conduit. All wiring MUST conform to the National Electrical Code and all local codes.
