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.

Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.

Based on 75°copper wire. All wiring must conform to the National Electrical Code and all local codes.

Maximum KW that can operate with the heat pump on is 9KW. Full heat available during emergency heat mode.

Maximum KW that can operate with the heat pump on is 10KW. Full heat available during emergency heat mode.
NOTE: The Maximum Overcurrent Protection (MOCP) value listed is the maximum value as per UL 1995 calculations for MOCP (branch-circuit
conductor sizes in this chart are based on this MOCP). The actual factory-installed overcurrent protective device (circuit breaker) in this
model may be lower than the maximum UL 1995 allowable MOCP value, but still above the UL 1995 minimum calculated value or
Minimum Circuit Ampacity (MCA) listed.
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.
