Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
Based on 75C copper wire. All wiring must conform to the National Electrical Code and all local codes.
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.
* Top outlet supply option is available only factory installed and only on the selected models.
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.
