These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electric 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 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 Electric Code and all local codes.
