These "Minimum Circuit Ampacity" values are to be used for sizing the field power conductors. Refer to the National Electric Code (latest revision), Article 310
for power conductor sizing.
Caution: When more than one field power conductor 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°C copper wire. All wiring must conform to the National Electrical Code and all local codes.
Maximum KW that can operate with the heat pump is 10KW for 1-Phase and 9KW for 3-Phase.
Represents Electric Heat only. Electric Control Circuit will lock-out Heat Pump Operation.
