The "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 (1) 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) conductors are in a raceway.
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.
Maximum KW that can operate with the heat pump on is 10KW. Full heat available during emergency heat mode.
Based on 75°C 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.
