These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest version), Article 310
for power conductor sizing. CAUTION : When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special
attention to note 8 of Table 310 regarding Ampacity Adjustment Factors when more than three (3) current carrying conductors are in a raceway.
k
Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.

Maximum KW that can operate with the heat pump on is 9KW. Full heat available during emergency heat mode.
m
Maximum KW that can operate with the heat pump on is 10KW. Full heat available during emergency heat mode.
n
Based on 75°copper wire. All wiring must conform to the National Electrical Code and all local codes.
IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses and conductor wires in
accordance with the National Electrical Code and all local codes.
