These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electric Co
de (latest version), Article 310 for power
conductor sizing.
CAUTION:
When more than one filed power conductor circuit is run through one conduit, the conductors must be derated.
Pay special attention to Note * of T
able 310 regarding Ampacity Adjustment Factors when more than three 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 (NEC) and all local codes.
